Data Request DocSpring API

I am using the docspring API for my app to populate PDF’s. The API works for generating basic PDFs but I need to update the pdf with a signature of two witnesses. I am following the rules of the documentation and I keep getting an error that it cant find my submission ID. Please help!

Here is the documentation for the Data Request

Hi Jovante,

The documentation for this is a little fragmented and if you scroll down further there is a second step by step page for this process: Data Requests (Electronic Signatures) · DocSpring Docs

This might help you navigate this process. The Data Request doesn’t have any submission ID there that I can see just a template ID. Have you got the response you were returned from the server that you can post?
