Where is the detailed documentation for Integration Service connectors?

I’m digging into the Integration Service and have some questions about how each of them are set up. Where is the documentation? Specifically, I’m interested in:

  1. Whether they use SSO or not, if so what other applications are they connected with?
  2. What events are available to subscribe to.
  3. How exactly the responses are formatted.

You can use the docs to see the details…might not contain the full structural details but would contain what custom datatypes are created and how to use

Each or most of the connectors have page like below which describes about activitiea and auth

Once you go to respective pages you can see the activities what api is used and what return types are allowed

Cheers
