Hi, Hope you are fine,
I am having an issue, related to calling API, it show 401 unauthorized, how can I resolve this.
And also it show 412. in some API request case.

Thanks in advance

Without seeing any of your code and how you are calling your endpoint, 401 is an unauthorised response, so have you passes a valid token? Or ticked bypass authorisation in the api/explorer?

412 response is a 'Precondition Failed', are you passing all the right parameters?

Code is needed for us to help you.
