Hi @RimaJ,
I suggest you test using Mock services, such as Postman, you can test the endpoint and payload that someone shared with you without creating entirely on the instance. That speeds up your development.
In the example above I'm testing an API from ServiceNow, but it could be any existing API.
As per your question regarding whether ServiceNow stores logs about integration, yes it does, you can find it below:
It is important to mention that you can also add gs.log(); in your Script Include code to log your payloads, and inbound HTTP calls to keep track of it. A side note is to comment them before go-live so you don't deploy with logs in Production.
If you found my answer helpful or correct in any way, please don't forget to mark it to help future readers! 👍
