REST API

Complete technical guidance on how to work with the Foundations REST APIs

The Foundations REST API will in-time replace our existing REST and SOAP web services, however, the existing REST and SOAP web services are not at this time being deprecated and will continue to operate side-by-side until appropriate notice given.

Introduction

The Foundations API is organised around REST. Our API has predictable resource-oriented URLs using standard HTTP response codes and verbs. All requests and responses, including errors, are JSON-encoded.

You can immediately start testing our APIs in sandbox mode by using our Interactive API Explorer. Please see our help page for support and information on preview / upcoming changes.

Service base location

Description

Authentication service

https://connect.reapit.cloud/

All other platform services

https://platform.reapit.cloud/

The current version of our APIs is 2020-01-31 - please include it in your api-version request header. For more information, see our versioning information

Our Platform is in beta and we'll be continually building new features during this phase. Please see our help section to view our milestones or to submit a feature request or bug.

REST

Request methods

Our APIs present a uniform interface for performing CRUD (create, retrieve, update, delete) operations. Each endpoint adheres to REST guidelines to map the correct verb to the operation being performed.

Our APIs support the following HTTP request methods:

Method

Action

GET

Retrieve a resource or collection of resources

POST

Create a new resource

PATCH

Partially update an existing resource by only including the fields to replace in payload

DELETE

Soft delete an existing resource

Response codes

We use standardized HTTP status codes to indicate the outcome of a request. Below is a listing of the codes our APIs may return and their meaning.

  • Codes in the 2xx range indicate that the request was fulfilled successfully.

  • Codes in the 4xx range indicate an error caused by the information provided.

  • Codes in the 5xx range indicate an error with our APIs which will be logged and investigated.

Code

Description

200 OK

The request has been fulfilled.

201 Created

The request has been fulfilled and a new resource has been created.

204 No Content

The request has been fulfilled but there is no need to send any data back.

400 Bad Request

The request was not understood by the server. This is generally due to bad request syntax.

401 Unauthorized

The provided authentication credentials are incorrect or not present. Generally, this is due to the lack of an "Authorization" header

403 Forbidden

The authentication credentials request do not provide sufficient scope to fulfill the request

404 Not Found

The requested resource was not found.

412 Precondition Failed

422 Unprocessable Entity

A validation error has occurred. The error response body will provide additional information on the failure(s).

429 Too Many Requests

The request was not accepted because the application has exceeded the rate limit.

500 Internal Error

The request triggered an unexpected error which will be logged and investigated.

Errors

In addition to the relevant response code, unsuccessful requests will return a JSON encoded error response as outlined below:

Attribute

Description

statusCode

The integer response code issued by this response

dateTime

UTC formatted timestamp of when error response was issued

description

Human readable message providing details about the error.

errors

A collection of validation issues with the provided payload. Only populated for 422 Unprocessable Entity responses.

All responses are issued with a unique request id, regardless of whether they were successful or not. You can find this in the x-amzn-RequestId response header. If you report a bug be sure to include this id to allow us to examine your problem in greater depth.

Rate limits

We apply rate limits on the API calls an application can make within a given time period. If this limit is exceeded the app will be throttled and API requests will fail.

  • 20 requests can be sent per second

  • 5 maximum concurrent requests at any time per customer

  • 250,000 maximum requests per day

If your application exceeds these limits, your app will be presented with 429 Too Many Requests responses.

Authentication

The Foundations platform uses OpenID Connect for authenticating requests. OpenID Connect is a protocol for authenticating users, built on top of the OAuth 2.0 specification.

Registering your app

Submitting your application to our AppMarket is the first step for it to be able to interact with our clients data. After you have successfully submitted your app, you will be issued with a client id and secret. You can obtain these by clicking your app in the My Apps area of our developer portal.

For more information on how to get started and register your application with our AppMarket, please see our developer portal guide.

Customer installation

You can immediately access our sandbox environment but in order to be authorized to access a customers data, they must choose to install it.

Customer administrators are able to control your applications access to their companies data by opted to install it once it has been listed in our AppMarket. As part of this process, they will grant your application with any permissions (scopes) it requires to interact with Foundations API endpoints.

OAuth 2.0 Grants

We support the use of two different OAuth 2.0 grants for applications built on our Platform:

Grant

Description

Authorization code flow

Client credentials flow

For use by server side machine to machine applications that do not have a user in context. Allows the implementing application to be authenticated on behalf of itself.

Client credentials flow

To obtain tokens for your application to interact with our protected endpoints, you must send a POST request to our token endpoint, as below:

https://connect.reapit.cloud/token

Request payload

Description

client_id

The unique client id that was issued to your application after registration

grant_type

Must be set to client_credentials

Content-Type must be set to application/x-www-form-urlencoded and the Authorization header should be set to Basic <base64 secret>where <base64 secret> is the base64 representation of the client id and secret concatenated with a colon. You can obtain client id and secret by clicking your app in the My Apps area of our developer portal.

If your request is properly formed and valid, you'll receive a response similar to below.

HTTP/1.1 200 OK
Content-Type: application/json

{ 
 "access_token" : "eyJz9sdfsdfsdfsd", 
 "token_type" : "Bearer", 
 "expires_in" : 3600
}

Response payload

Description

access_token

Token to grant access to protected Foundations endpoints

expires_in

The number of seconds that the access token is valid for

token_type

The type of tokens issued. Will always be set to bearer

Client credentials flow must not be used for applications that are client side only. A server side component is required to be able to safely store credentials.

Using access tokens

Access tokens (also known as bearer tokens) are designed to provide your application with access to protected resources. Once you have been issued an access token from our token endpoint, your application can access Foundations APIs by including it in aAuthorization header, prefixed with Bearer

Authorization: Bearer <your access token>

Our servers will validate this token and fulfill the request, subject to your application application requesting the relevant endpoint scope during registration.

Accessing customer data

Requests issued with access codes gained from the client credentials flow must also indicate which customers/agents data they wish to interact with.

You must additionally include a reapit-customer header in your request so that it can be fulfilled appropriately. The header should be set to the customers unique id which becomes available to view after a customer has chosen to install your application. You can find out the unique ids and names of the clients that have installed your application via the installations section on your app in the DeveloperPortal. Please click here for more information on installation data.

If a customer chooses to uninstall your application then your access to their data will be revoked.

Please note that the resource identifiers are only unique to a specific customer's database and not globally unique. To determine uniqueness, create a composite key using the customer id and resource id.

We recommend using our webhooks system to be instantly notified when a Reapit customer installs your application. See our webhooks documentation for more information.

Sandbox mode

You can use the Foundations APIs in Sandbox mode which provides a set of demonstration data that can be interacted with without requiring a customer to install your application. Sandbox mode supports processing of all read and write requests so that you can build and test in confidence without impacting customer data.

To access the sandbox, you just need to be registered as a developer on our Portal.

  • You can use authorization code flow by providing your developer portal credentials to our Reapit Connect service

  • You can use client credentials flow by providing SBOX as your reapit-customer request header

For a quick start experience, our interactive API explorer is connected to the sandbox automatically

Issuing requests

Timestamps

The Foundations platform exclusively works with UTC date times to allow us to present a uniform interface and ensure that behavior remains predictable, regardless of your application or user timezone.

Our APIs enforce that any date information that your application issues to us adheres to the ISO-8601 format. If you provide a time component, then it must be accompanied by a time zone designator. If you provide a request body, query string or header that does not adhere to this standard, you will receive a validation error reporting the problem. Any date times issued from our endpoints will be returned to you in the same format.

Some of the fields we provide are date-only and have no time component. Date only fields will not accept a time component in a request and will not include a time component in their response. You can see which fields these are by examining the model documentation and example responses provided by our Interactive API Explorer.

{
  "myDateAndTimeField": "2020-02-11T13:32:03.6759302Z",
  "myDateOnlyField": "2020-02-11"
}

Retrieving data

Our APIs support retrieval of resources using the GET verb. When a GET request has been successfully fulfilled, you will receive a 200 OK response with results included as a JSON payload. To ensure that parameters that GET resources accept work as you expect, please ensure you URL encode the parameters you provide.

When working with boolean query string parameters, if they are not provided then no filter is applied to the dataset returned. This can be confusing for some developers who assume that not passing these parameters is like passing them as false (typically the default value for a boolean property). If they are not passed at all, our APIs ignore them completely and so no filtering is applied to the respective field(s).

For practical and performance reasons, our top level APIs enforce paging and require a standardised set of query strings in their requests. The pageSize and pageNumber parameters are used to cycle through the available results from a top level API.

For example, GET /contacts?pageSize=10&pageNumber=2 will return the second page of ten contact resources in the following structure:

Response payload

Description

pageSize

The requested number of records per page. Default is 25 and maximum 100 unless specified

pageNumber

The page number that this response represents

pageCount

The actual number of records that the current page contains

totalPageCount

The total number of pages available in the response

totalCount

The total number of resources available that fulfil the criteria of the current request

_embedded

The list of resources that have been returned in this paged response

Extras field If you represent an AgencyCloud customer and require access to data held in the 'extras' semi structured field, please submit a GitHub developer request using the issue template provided.

Creating data

Our APIs support resource creation using the POST verb. When a creation request has been successfully fulfilled, you will receive a 201 Created response.

The body of a POST request should always be sent as a JSON object, with the Content-Type header set to application/json

Since the creation of new resources is often asynchronous, we do not include the payload of the newly created resource in the POST response. Instead, we include the the location of where the new resource can be retrieved from in the Location header of the POST response.

Updating data

Our APIs support resource updates using the PATCH verb. When an update request has been successfully fulfilled, you will receive a 204 No Content response.

The body of a PATCH request should always be sent as a JSON object, with the Content-Type header set to application/json

When you provide an update to use using the PATCH verb, you're able to only update the parts of a resource that you care about, rather than completely replacing the entire resource. Usage is simple and you just need to specifically send us the data you wish to update.

The below example will only update the notes field on a representation that may allow you update many other attributes:

{
  "notes": "Returned Mr Johnsons Call",
}

As with resource creation, we do not include the updated resource in the PATCH response. Instead, simply re-fetch the latest state of the resource by issuing a GET request.

Uploading files

The following APIs allow consumers to upload certain types of documents to the Reapit Platform:

  • documents

  • propertyImages

  • identityChecks

Each respective APIs POST endpoint supports uploads of content up to 6Mb in size, however we understand that there may sometimes be a legitimate need to upload larger files. To support this requirement, it is possible to obtain a pre-signed URL from each of these APIs which you can then send your data to.

Please note that the 6Mb limit is the combined size of the different request components (headers, body etc). As a result the limit of the size of the encoded file being uploaded will in fact be slightly less than 6Mb. In the case of endpoints that accept multiple documents, for example the POST /identityChecks endpoint, the total request size cannot exceed 6Mb.

Using pre-signed URLs

To upload larger files (between 6Mb and 30Mb), a pre-signed URL should be obtained from the Platform and used to upload your data. Each of the APIs listed in the Uploading files section of this documentation has a POST /signedUrl endpoint which can be called to generate up to 10 pre-signed URLs. This can be useful where you need to upload more than one file.

Use the following request body when calling the endpoint, setting amount to a value between 1 and 10 to have the respective number of URLs returned to you

POST /documents/signedUrl
{
    "amount": 2
}

The response will contain a collection of URLs which can then be used to upload your content to, along with an expiry date for the provided URLs, which will expire after 15 minutes

  ],
  "expiration": "2021-07-14T08:42:53.6452618Z"
}

To then upload your file to the presigned URL, you will need to make a PUT to that URL with the 'Body' type set to 'Binary File'. Upload the file and 'Send'.

When the file has been uploaded, you will still need to use the main POST endpoint of the relevant API to store your file to a customer's file system. Rather than sending the base64 encoded file content in the fileData property, you should use the fileUrl property and send the pre-signed URL that the file was sent to. The platform will then transfer the file from the holding area to the relevant customer's file system. It is not necessary to include all the query string parameters from the pre-signed URL in the subsequent POST, as per the example below

POST /documents
{
  "associatedType": "property",
  "associatedId": "OXF190347",
  "typeId": "DET",
  "name": "24 Smithson Road Details.pdf",
  "fileUrl": "https://reapit-file-uploads-prod.s3.eu-west-2.amazonaws.com/443e4a98-dfcb-4345-abb2-e52031928ed1",
}

Request validation

To protect the integrity of our clients data, we enforce proper validation on all POST and PATCH requests

Should your request not pass the validation requirements of the endpoint, then you'll be issued a 422 Unprocessable Entity code. The error response will include a listing of validation problems and how you can solve them.

{
  "errors": [
    {
      "field": "type",
      "message": "The enum value provided for AreaType is incorrect"
    }
  ],
  "statusCode": 422,
  "dateTime": "2020-02-11T13:32:03.6759302Z",
  "description": "One or more validation failures have occurred. Please refer to Errors list for details"
}

Optimistic concurrency

Our APIs serve Platform functionality and data to various different applications and users at the same time, which needs to be managed carefully to avoid concurrency problems.

In some systems, when multiple systems perform updates at the same time without knowledge of each others changes, you can be left with the problem of lost updates whereby the last update "wins" and previous updates are lost. Our APIs enforce optimistic concurrency control to help avoid this problem.

We use entity tags as an indicator of the current version of any resource returned from our APIs and whenever a singular representation is served by any of our GET endpoints, it will include eTag in the response header. For convenience, we also include this as an _eTag attribute in the response for each object.

This gives both client and server a means of understanding the version of a particular resource an application has received. Subsequently when a resource is updated, it's eTag value will also be updated.

To ensure that updates aren't lost, you must include an If-Match header in your PATCH request containing the eTag value exactly as you received it including quotation marks. The server will then compare its version of the resource with the eTag you provided.

  • If they match, then the update is intended for the same version of the resource and the request will be processed

  • If they do not match, then the resource has been updated since it was fetched and the request will be rejected with a 412 Precondition Failed error response

If rejected, you need to retrieve the latest version of the resource and replay your changes before attempting another update.

For more information about entity tags and our implementation of conditional requests, please see RFC 7232

Versioning

As we evolve our platform, new features will be added and fixes will be made. We categorize changes in two ways: breaking and non-breaking changes. We make every effort to implement changes as non-breaking wherever possible, however, there are sometimes situations that require this.

Whenever a breaking change is introduced into our platform we release a new, dated version. The current version is 2020-01-31.

All requests should indicate the version that should be used to fulfill them. You can do this by including the header api-version set to the dated version required.

Breaking changes

We consider the following to be examples of breaking changes:

  • Renaming or removing an existing field or endpoint

  • Changing the URL structure of an existing endpoint

  • Changing the filters that an existing endpoint provides

  • Changing error response codes or messages that an endpoint provides

  • Modifying or adding a new validation to an existing resource

  • Changing the data type of an existing field

  • Requiring a parameter that wasn't previously required

Deprecation

Whenever a new version is released, the previous version enters its sunset period. This is presently six months though will be reviewed as our platform continues to grow and evolve.

At the end of a versions sunset period it will become deprecated and you will be required to adopt more recent version. You will be notified if your application is using a version that is soon to be deprecated.

Stay up to date: please see the help section of our developer portal for information on recent and upcoming changes.

Metadata

Our metadata system allows you to easily extend the data that our platform supports. Most of our POST and PATCH endpoints provide the ability to attach a JSON document to our entities which will be automatically included in future fetches of that entity.

We also provide specific metadata endpoints for more direct, granular control on the data you provide. You can use these same endpoints to build new, standalone entities that are specific to your application without needing to hosting your own datastore.

Metadata is specific to a customer and any data that your application sets will not be made available to users of your application who represent a different customer. We do not recommend using metadata storage for any sensitive information (personally identifiable details, bank accounts, etc).

Attaching metadata to our entities

The easiest way to work with metadata is to populate the metadata attribute on our existing endpoints. You can provide a JSON document in the PATCH or POST payload as below: 

{
  <rest_of_payload>
  ...
  "metadata": {
    "MyCustomField1": "MyCustomValue1",
    "MyCustomField2": true
  }
}

Once metadata has been set against an entity, it will be automatically returned in the same format for future GET requests originating from your app.

For more granular control, you can use our dedicated metadata endpoints to create, update and retrieve outside of the context of one of our Foundations endpoints.

Creating custom entities

You can use these metadata endpoints to use Foundations as a simple datastore. You can create a standalone entity by providing a custom entityType with your JSON payload. You can then fetch, filter and update your entity using the /metadata REST endpoints we provide.

{
  "entityType": "myCustomEntityType",
  "entityId": "75c46440-5cb9-4db1-801d-f57eab8999e2",
  "metadata": {
    "CustomStringField": "my string",
    "CustomBoolField": false,
    "CustomNumericField": 100.5,
    "CustomDateField": "2019-06-15T13:45:30Z"
  }
}

If you'd like to associate your custom entity with an entity your hold outside of Foundations, you may pass in an entityId which you can later use for searching/filtering. If you do not, an entityId will be generated and returned to you automatically.

Validating custom entities

Our metadataSchema endpoints allow you to provide a JSON Schema to validate the metadata JSON document that you provide the platform. Once you associate a schema with a custom entity type, you it will be used to validate future metadata submissions for entities of that type. If this content does not conform with the JSON schema you've provided for that entity type, the request with fail with a 422 Unprocessable Entity response and a listing of the reasons why validation failed. For more information, see our Swagger documentation.

Searching for metadata

Once metadata has been set against an entity, its content can then be used to re-locate that entity by using your metadata as a search term. The metadata query string parameter accepts a filter expression to identity the record(s) required in the following prescribed format:

GET /<endpoint>?metadata=metadata.<fieldName> <operation> <criteria>

Failure to adhere to the format required will provide a 400 Bad Request response detailing the problem. If you are having trouble, consult our example usage guide below.

Search operations

We support querying using up to eight different filter operations, depending on the data type of the metadata field you’re searching upon.

Additional information

  • Metadata filtering is not case sensitive

  • Metadata filter expressions are additive and can be used any number of times by providing the metadata query string more than once

  • Metadata filter expressions can be used in conjunction with any other query string parameter that an endpoint makes available.

  • Metadata filtering can use the dot notation format to search for data stored in a nested structure.

Hypermedia

Our APIs are REST level 3 and implement hypermedia controls to improve the developer experience of using our platform. Hypermedia makes our APIs self documenting, easier to use and aids discovery. We adopt the HAL hypertext application language to serve as our message format.

Links

Each GET response provides a uniform interface to present links to demonstrate which data is related and how that data can be retrieved. This is particularly useful for APIs that present complex systems of interrelated data, such as ours.

Each resource, including collection resources, include a _links collection to present related data. The responses _links dictionary will include a key to represent the type of relationship and a value to represent the location where the related resources can be obtained from.

The condensed GET /contact/{id} payload example below demonstrates how relationships are presented:

{
  "id": "OXF18000001",
  "created": "2018-02-12T09:45:01.0000000Z",
  "modified": "2019-06-23T12:30:12.0000000Z",
  "title": "Mr",
  "forename": "John",
  "surname": "Smith",
  "dateOfBirth": "1992-08-12",
  "homePhone": "01234 567890",
  "mobilePhone": "07890 123456",
  "email": "example@email.com",
  "officeIds": [
    "OXF"
  ],
  "negotiatorIds": [
    "JAS"
  ],
  "_eTag": ""33a64df551425fcc55e4d42a148795d9f25f89d4"",
  "_links": {
    "self": {
      "href": "/contacts/OXF18000001"
    },
    "documents": {
      "href": "/documents/?ownerType=contact&ownerId=OXF18000001"
    },
    "identityChecks": {
      "href": "/identityChecks/?contactId=OXF18000001"
    },
    "offices": {
      "href": "/offices/?id=OXF"
    },
    "negotiators": {
      "href": "/negotiators/?id=JAS"
    }
  },
  "_embedded": null
}

In the example above, the presence of the identityChecks key indicates that there is a related resource available. The value contains the service location and query string parameters required to retrieve the related identity check resources.

Embedding data

Many of our GET APIs provide the ability to compose requests that automatically embed related data in their responses. This is a convenient tool that reduces the number of round trips your application needs to make to our Platform. Using this mechanism can result in improved application performance with less API interaction code required.

If your application requires data from one or more related resource(s) (indicated by a link), you can simply specify the name of the related resource in the embed parameter and our APIs will do the rest. So long as the related data exists, it is returned to your app in the correct resource(s) _embedded data collection.

This mechanism allows your application to make fewer round trips to the server by allowing our APIs to make requests on your applications behalf. Any request triggered by the embed mechanism will still contribute to your usage statistics in the same way as if they were directly issued from your application. See the Billing Example for further information

You can embed as many related data sources in a request as your application requires. Our interactive API explorer provides a user interface which demonstrates the available embed parameter options for each API.

Example

GET /contacts/OXF18000001/?embed=offices&embed=negotiators

The request above illustrates the means of requesting that related office and negotiator resources are included with the response from the contacts API. The condensed response below demonstrates how these related resources are returned within the contacts payload in the _embedded attribute.

{
  "id": "OXF18000001",
  "title": "Mr",
  "forename": "John",
  "surname": "Smith",
  "officeIds": [
    "OXF"
  ],
  "negotiatorIds": [
    "JAS"
  ],
  
  <rest of contacts payload>
  
  "_links": {
    "self": {
      "href": "/contacts/OXF18000001"
    },
    "offices": {
      "href": "/offices/?id=OXF"
    },
    "negotiators": {
      "href": "/negotiators/?id=JAS"
    }
  },
  "_embedded": {
    "offices" : [
      {
        "id": "OXF",
        "name": "Oxford",
        "manager": "David Brown",
        "address": {
          "buildingName": "",
          "buildingNumber": "1a",
          "line1": "Wellington Square",
          "line2": "Brownhaven",
          "line3": "Oxford",
          "line4": "",
          "postcode": "OX1 2JD"
        },
        
        <rest of offices payload>
      }
    ],
    "negotiators" : [
      {
        "id": "JAS",
        "name": "John Smith",
        "jobTitle": "Senior Negotiator",
        "active": true,
        "officeId": "OXF",
        "email": "drew.mcculloch@reapitestates.net",
        
        <rest of negotiators payload>
      }
    ],
  }
}

Billing Example

It can be difficult to understand how using the embed mechanism affects your usage and overall bill. As mentioned previously, requests made using this feature are billed as though you made the request yourself. All embed operations use the maximum page size of 100 resources per page to limit the number of background API calls.

As an example, considering the following request:

GET https://platform.reapit.cloud/properties?embed=images&pageSize=50

If the above request returns 50 properties and each property has a total of 15 images, your usage is calculated as follows:

1x request to properties endpoint

(50 properties * 15 images per property) / 100 = 8 requests to the property images endpoint as there are 7 full pages, and one partial page of images

Total of 9 billable calls
