I am working on the integration part of our S4HC implementation project.
I have activated some APIs in S4HC and I used to try them through web browser or Postman tool.
This was working well, but since few days it does not anymore.
I have the following message :
It looks like an authorization problem, but the authentication method to access the APIs is "User ID and Password". And the User ID and Password provided are OK.
Do you know how to solve this?
Many thanks for your help.
