Hey There,
I hope you are having a great time.
I am using the Postman Collection and Environment, been provided via email, and I can hit the API's we need correctly using Postman. I looked into the Quick Start link, been shared with us and I got the sample JavaScript code for hmac signature creation, over here. We have also tested this JavaScript code in the Postman Pre-request Script but it is throwing an error.
We translated that code to Php but it is not creating a valid hmac and we are getting a 401 Unauthorized response, whenever we hit an API from our code/application. Even though we used the hard coded values, the same as the Postman request is using, it doesn't generate a valid hmac.
Can we get any help here?
