As shown in the examples throughout this documentation, different API operations are executed using either GET, POST, PUT, PATCH, or DELETE requests. However, Flash applications must send a POST request in order to set an Authorization header.
To send an authorized GET, PUT, PATCH, or DELETE request from a Flash application, set the
X-HTTP-Method-Override header in that request. If your application is sending a GET request, it should set the body of the request to the query parameters associated with that request as shown in the following example:
POST /feeds/api/videos HTTP/1.1 X-HTTP-Method-Override: GET Host: gdata.youtube.com Content-Type: application/atom+xml Content-Length: CONTENT_LENGTH Authorization: Bearer ACCESS_TOKEN GData-Version: 2 X-GData-Key: key=DEVELOPER_KEY vq=jesse+ventura&category=News
If your application is submitting a POST or PUT request, it should set the body of the request to an XML document. The XML formats for different types of requests are defined in later sections of this documentation.
