Gravity Form Not Posting to endpoint

I have a Gravity from that was created and the submission needs to be passed to a URL. My developer created a PHP function to pass the form. The other party that the form is being passed to is not seeing the form come through. I have looked at the error log and the last line says:
GFCommon::log_debug( 'gform_after_submission: body => ’ . print_r( $body, true ) );

There is nothing after it showing the form was passed. The other partner thinks that the function is not being called by the form.

Thoughts? Happy to share more details.

I recommend opening a support ticket for this issue. There is too much information to gather to be able to help efficiently in the community forums:
