Request Parameters
Data retrieval services typically include standard parameters for searching, sorting, and pagination. Take a look at the Oasis OData Documentation for more details.
Attribute Selection
The $select parameter allows you to specify the top-level data components you need. For larger data sets,
such as properties, using this parameter will greatly reduce data retrieval time.
| Parameter | Description |
|---|---|
$select |
A comma separated list specifying the attributes to be returned in the response payload. |
Pagination
Pagination allows data to be retrieved in sets of a specified size and provides additional data about the result set.
| Parameter | Description |
|---|---|
$top |
Integer > 0 and <= 25 indicating how many results to return at once. The default is 10. For keys with the replication role it may be > 0 and <= 1000. |
$skip |
Indicates the number of records to skip over when retrieving the current results set. |
$count |
Boolean true or false. Indicates if the number of records in the total result set should be returned. Default is false. |
Sorting
Sorting is typically available on resources that allow searching.
| Parameter | Description |
|---|---|
$orderby |
Indicates the order in which to return records in the result set. Each service has its own default order. |
Any searchable field can be present in the $orderby parameter, with some exceptions (e.g. longer text fields such as PublicRemarks for properties).
Searching
Request parameters below are common to data retrieval services supporting searching.
| Parameter | Description |
|---|---|
$filter |
OData filter syntax is used for filtering. Documentation can be found here. |
Expansions
Request parameters below are common to data retrieval services supporting pulling related entities.
The most basic example is to retrieve both media and listing data with a single call to the API. This can be done by including the $expand=Media parameter in a request on the /Property endpoint.
You are also able to pass pagination and search parameters that interact exclusively with the expanded entity. The syntax for such a request is $expand=Media($top=1) and the result of this particular example is the retrieval of a single media record for each listing in your payload.
| Parameter | Description |
|---|---|
$expand |
OData expansion syntax is used for expansions. Documentation can be found here. |
