How to sniff Adobe Flash application traffic?

Question

Traffic analysis

Adobe Flash sends POST requests and receives responses over HTTPS. The body of the request contains data in the AMF format.
You need to get the entire request (both headers and body) so that you can then send it not through Flash.
Is this even possible in theory?
I tried 3 sniffers decrypting HTTPS traffic by replacing the certificate, and in none of the cases did I manage to get anything but the headers.
