is it possible for me to send data to a Facebook tab using get requests? or can I only post data through the iframe to the page that I want to receive the data and let the iframe load like that as I’m trying to using the Twitter Authentication through a facebook tab.
Also why am I not allowed to send data using a get request to a facebook tab?
You cannot use GET requests on a Facebook tab but you can pass data through the *app_data* variable.
Try this:
You can access MY_DATA through the *signed_request* parameter. More about *signed_request* here:
