Send a Form-URL-Encoded REST Request

See more REST Examples

Demonstrates Rest.FullRequestFormUrlEncoded, which sends an application/x-www-form-urlencoded request. The body is built from the query parameters added to the object, and the response body is returned as text.

-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls.
