IFS10 REST API – Basic Authentication Returning 401

Hi,

We are using IFS Applications 10, and I’m currently developing a web application that integrates with IFS. In the previous version, I was using SOAP services, but now I’m switching to REST APIs after upgrading.

As far as I know, Basic Authentication should be enough for accessing IFS10 REST endpoints.
As a test, I’m trying to call a Quick Report GET endpoint via Postman, using Basic Auth with a valid IFS user.

However, I always receive a 401 Unauthorized response, even though the credentials are correct.

Any ideas on what might be missing? Do I need to configure something on the IFS side, or are there special headers or tokens required?

Thanks in advance.

I fixed it by adding the projection to compatibility application type😁
