1. Can you let me know how to do that? When I render the endpoint on browser, it throw error saying "GET method not supported for API" - which is accurate but how do I test the reachability for this POST API?

2. The credentials are correct. Like I said earlier, it is the same credentials with which I am executing in the original NOW instance

3. How do I check for firewall rules? I am able to execute my custom API using the same credentials through POSTMAN. It's just the OOTB api that is failing.

4. json payload is correct. Like I said earlier, it is the same payload which I am using in the original NOW instance

5. I dont see any logs

6. How do I check if this OOTB api is exposed and enabled for external access?
