Getting Started
To get started using the MLS Router API, please sign up on RF Dashboard. (How to Sign Up on RF Dashboard)
When we set up your account, we'll provide a Client ID, Client Secret, and an API key that you'll need for use in API requests.
Authentication
To access the MLS Router API, authentication is required. The API uses the OAuth2 Client Credentials flow for authentication.
Obtaining Access Token
To authenticate, send a POST request to the following endpoint:
POST https://realtyfeed-sso.auth.us-east-1.amazoncognito.com/oauth2/token
The request should include the following in the Request Body:
Parameter | Description |
|---|---|
client_id | The client ID provided by Realtyna |
client_secret | The client secret provided by Realtyna |
grant_type | The grant type, which should be "client_credentials" |
And also include the following in the Request Headers:
Parameter | Description |
|---|---|
Content-Type | application/x-www-form-urlencoded |
Accept-Encoding | gzip, deflate, br |
Accept | */* |
If the authentication request is successful, you will receive a JSON response with the following values:
{
"access_token": "<access_token>",
"expires_in": 3600,
"token_type": "Bearer"
}
access_token: This is the authorization token that needs to be passed in the Authorization header of API requests.expires_in: The duration of validity for the token in seconds (currently set to 3600).token_type: The type of token being returned (currently set to "Bearer").

Reading the Metadata
Once you've authenticated, the next step for building a client is finding out what data you can get out of MLS Router API. To do this, you query the metadata endpoint.
GET https://api.realtyfeed.com/reso/odata/$metadata
Now that we know what fields are available via MLS Router API, it's time to start fetching property data.
Retrieving Data
To retrieve data from the MLS Router API, please include the following headers in each request:
Authorization: Set this header with the value "Bearer <access_token>" (replace<access_token>with the actual access token obtained during authentication).x-api-key: Include this header with the API key provided by Realtyna.Origin: Include this header with the API key provided by Realtyna. (Optional)Referer: Include this header with the API key provided by Realtyna. (Optional)
The endpoint structure of all search requests is:
GET https://api.realtyfeed.com/reso/odata/{resource}
Valid resource values include the names of the valid RESO resources: Property, Member, Office and OpenHouse.
RESO Media is nested within the Property Resource.
By default, MLS Router API returns 10 records per query. If this is your first foray into MLS Router API, it will be enough for you to learn about the structure of the data that's returned.
Parameter | Description |
|---|---|
@odata.nextLink | URI for getting the next set of records. Will only be present when there are more records to retrieve. |
value | An array of objects. The data you came for. |
While you look through the data you have pulled back, there is one field that you should pay special attention to: ListingKey. This field is the unique identifier for the Property record.
ListingKey is the unique identifier for Property records
Request Parameters
The MLS Router API supports the following parameters for search requests:
Parameter | Description |
|---|---|
$top | To get more records per query, we use the $top parameter. If you want just one record, you can specify $top=1, or if you want one hundred, $top=100. (default is 10 - max value is 200) |
$skip | Use $skip to skip over a number of records. This is most useful in combination with $top to iterate over the results of a query. (default is 0) |
$select | You can limit the fields you want with $select. For example, if you want just the ListingKey and the StandardStatus, you would use $select=ListingKey, StandardStatus. If you want all the fields, you would use $select=ALL |
$filter | You can get specific records you want with the $filter. |
$orderby | You can sort results via the $orderby parameter. This parameter accepts “ASC” and “DESC” as an argument (default is “ASC”). |
The supported parameters can be combined as needed
$filter
The $filter system query option restricts the set of items returned. MLS Router supports a set of built-in filter operations, as described in this section:
Operator | Meaning | Example |
|---|---|---|
eq | Equal To | ListingKey eq '123456' |
ne | Not Equal To | PropertyType ne 'Residential' |
gt | Greater Than | BedroomsTotal gt 3 |
ge | Greater Than or Equal To | BathroomsTotalInteger ge 2 |
lt | Less Than | ListPrice lt 350000 |
le | Less Than or Equal To | LotSizeArea le 5 |
and | Both conditions are true | BedroomsTotal eq 3 and BathroomsTotalInteger eq 2 |
or | Either condition is true | BedroomsTotal ge 3 or BathroomsTotalInteger ge 3 |
in | Value is in List | StandardStatus in ('Active', 'Pending') |
These operators can be combined to form very complex queries, e.g. ((ListPrice lt 300000 and LotSizeAcres lt 3) or (BedroomsTotal gt 4 and StandardStatus eq 'Active'))
Working with strings in $filter:
Strings are relatively straightforward in MLS Router API. They are always enclosed in single quotes (') and if you need a single quote in the string, you simply double it up, e.g. 'O''Brien'.
In addition to all of the basic operators that you can use with strings, there is a function to help out as well:
Function | Description |
|---|---|
contains(haystack, 'needle') | Returns true if needle is found in haystack |
Working with geo coordinates in $filter:
Function | Description |
|---|---|
geo.distance(Coordinates, POINT(-96.818747 32.928812)) lt 10km | Returns property listings within geo distance of 10km from a specific point |
Retrieving Single Record
Use this endpoint to get details about a specific record:
GET https://api.realtyfeed.com/reso/odata/{resource}('resource_id')
The API returns record within the specified resource having a primary key value matching the provided resource_id. For example:
Request
GET https://api.realtyfeed.com/reso/odata/Property('ListingKey')
or
GET https://api.realtyfeed.com/reso/odata/Member('MemberKey')
Don’t hesitate to contact Realtyna Support, if you have any questions.
Errors
401 Unauthorized
A 401 http response results when authentication fails. This is likely due to using an invalid x-api-key or account suspension.
403 Forbidden
A 403 http response results when an authenticated user does not have adequate permissions to perform the requested operation or access the specified resource.
400 Bad Request
A 400 http response results when a request is poorly formatted or does not meet validation for the specified operation.
400 responses contain an array of messages that a developer may parse to determine the parameter and reason for why the request failed.
406 Not Accepted
A 406 http response results when a request is not satisfied due to rule or policy being broken.
500 Internal Server Error
A 500 http response results when an unexpected problem occurs with a request. If after several retries the 500 error still persists, it should be escalated to the Realtyna Support Team for troubleshooting.
