OAuth 2.0 Client Credentials Flow: INVALID_LOGIN_ATTEMPT

edited Jun 2, 2025 2:25PM in Ask A Guru 15 comments

Release 2021.2 introduces the Client Credentials Flow.

What we have done:

  1. Setup (https://docs.oracle.com/en/cloud/saas/netsuite/ns-online-help/section_162686838198.html)
  2. Post request to the Token Endpoint (https://docs.oracle.com/en/cloud/saas/netsuite/ns-online-help/section_162755359851.html) -- this, after correcting the error in the documentation (the parameter is "client_assertion", not "assertion"), indeed returns an access_token
  3. Invoking a restlet (https://docs.oracle.com/en/cloud/saas/netsuite/ns-online-help/section_157780293862.html) however fails with INVALID_LOGIN_ATTEMPT

The access_token returned in step 2 contains "scope": [ "restlets" ] which we believe should be sufficient. (adding the "rest_webservices" scope does not help)
