Hi,

I would like to highlight an observation that I made on the path that you have declared in the code i.e "https://rms-world-check-one-api-pilot.thomsonreuters.com/v2/cases" which is for the endpoint to save a case API(async screening) and I also see that in dataToSign section of the code the endpoint declared is of sync screening i.e. "cases/screeningRequest".

There is an obvious discrepancy here and I believe this might be the potential cause for the 401 that you're observing. Please clarify the endpoint that you would like to use i.e. save a case or sync screen a case and make the corrections accordingly under the path and dataToSign section of your code.

Let me know if this solves the issue.

Regards,

Mehran Khan

APIs are working fine in postman but not in python they are returning 401

Please edit the endpoint detail in your dataToSign section to just "cases" from "cases/screeningRequest".

Let me know if this works.
