Hi @Irfan.Khan,

I was finally able to resolve it. I downloaded the latest Postman collection from the developer site. Seems like the one I was sent was not functional. Thank you

Can you provide me the complete request and response from the postman logs for the failed API call?

You can go to View-> Enable the console logs by clicking Show Console Logs.

Thanks for sharing the details, Kindly check the URL that is being formed in your request, One way to make sure of this is to check the values for the environment variables "gateway-host", "gateway-url" in your postman environment.

I am copying a sample request & response below for your reference, let me know if you need further assistance in setting up your postman correctly,

I adjusted the uri based on your comment and I still have the error:

I notice that the Authorization headers you are sending using Postman is incorrect. The Authorization header you are sending is:

Authorization: Signature keyId="20-XXXXXXX-a7c9-eb2f20b3bb16",algorithm="hmac-sha256",headers="(request-target) host date content-type content-length",signature="JfK+b4SNBYTIuQbZvDWjM7Md28ry45KHji//GpgXHvs="

The text marked in bold should not be a part of the header, I am not sure why Postman is sending this information.

The correct authorization header should be:

Authorization: Signature keyId="dbbb1639-b83a-496b-b906-0cdf8f5*****",algorithm="hmac-sha256",headers="(request-target) host date",signature="Pnz+TORZqp4teeYup7KGNQCTTfE0mF0JxLcGM46NFtY="

Request you to delete the existing postman collection and environment currently in your Postman app and re import the collection and environment attached in this post and re test again.

Please follow the steps mentioned in the link below:

Kindly let me know if this works.
