{Dynamics 365 WEB API} Create entity record with data returned

What’s new for developers: Microsoft Dynamics 365

Sometimes you want to retrieve an entity right after you create or update it. Earlier, you needed to use two operations. The POST request to create an entity returns an HTTP 204 (No content) status and a Uri to the entity created is returned in the OData-EntityId header property. You can then use this Uri with a GET request to retrieve the created entity. This is because the default preference is to apply the return=minimal preference.

You can compose your POST request so that data from the created record will be returned with a status of 201 (Created). To get his result, you must use the return=representation preference in the request headers.

To control which properties are returned, append the $select query option to the URL to the entity set. The $expand query option will be ignored if used.

When an entity is created in this way the OData-EntityId header containing the URI to the created record is not returned.

This example creates a new account entity and returns the requested data in the response.
