A new type of Facebook lead generation (leadgen) form is being configured by Optimyzd that will allow scheduled style callbacks to be requested directly from Facebook adverts.
This will require a new handler in the Callback service to be configured that will deal with the new data fields that will be sent with the leadgen. The handler will build upon the existing instant callback handler.
For reasons unknown, the Facebook-provided testing tools to not work correctly with this type of form. It was incorrectly reporting that the request was not being sent to the new handler. After further investigation, this was found to not be the case.
As such, the development stalled a bit, but it is now continuing. A test version of the handler will be made available for testing (Monday) 21-08-2023. Since the handler builds upon the existing handler, testing should be minimal. It will be necessary however to have access (somehow) to the correctly rendered version as it is in the ad, as the Facebook testing tool shows an incorrect version.
