I want to enter data through postman in one of our customer’s test environment. I tried connecting to the environment using Basic Auth as Authentication type, but it’s giving an error.

How can I connect postman to this environment? Is there a different Authentication type that I can use?

Following is in the API Documentation. This is a 25R1 environmet.

Yes, you can find information in the IFS technical documentation about this:
https://docs.ifs.com/techdocs/26r1/040_tailoring/300_extensibility/010_get_started/300_authentication_and_authorization/#steps_to_set_up_a_client_credentials_flow

 

Especially this links to examples is good:
https://docs.ifs.com/techdocs/26r1/040_tailoring/300_extensibility/010_get_started/400_quickstarts/010_auth/#authentication_and_authorization

Observe that the IAM Client you use should have a user assigned to it and that user needs to have proper permissions to projections. Possibly also companies and sites if the data you want to fetch is depending on that.
