FileMaker and Adobe Sign Intergration

We are looking to integrate Adobe Sign with our FileMaker solution. While I have a decent gasp on FileMaker and that fun stuff, Not all that great with the scripting and api integration. We are looking to be able to send out a service agreement that we generate in FileMaker for signatures. I know we can send it as a PDF. Do you know if it’s possible to also then grab the signed PDF and put it back into FileMaker? I know that this can be done with DocUsign.

Any suggestions or links would be awesome.
