Custom GPT Schema Help Alassian Spwiki information retrieval

Hello all,

I am currently struggling with writing the Schema for my custom GPT. I want to add an action that allows it to connect with my Atlassian Spwiki which contains all the information that I am using for different projects and files, and answer my questions using that information.

Are there any comprehensive guides I can follow to writing the schema in order to get this working? I tried the documentation but I couldn’t find what I was looking for / it was too complicated for my smooth brain.

Or does anyone have any input?

Thanks in advance
