/v2/ 401 Unauthorized response in Postman

I am struggling to do the first call to the API, ie GET /groups - I keep getting a 401 error, even though I believe I followed the steps properly (I have set api-key and api-secret as environment variables in Postman and i'm using the postman collection provided by the documentation).


here's the Postman log (I've replaced the values for keyId and signature):

@togetherdevs,

The gateway host which you are using is incorrect. Can you please use - 'api-worldcheck.refinitiv.com' and try again?

Thanks it worked. Please update postman collection in documentation downloads since it is outdated. I got the wrong url from that collection

Do both environments have the same gateway host?

Yes, the hostname for production and new pilot instance is the same, please get in touch if you need any assistance with this.
