Hi All,

I'm trying to integrate the ServiceNow with the postman while pushing the code and the data was not getting from the postman, the issue was the user was not authenticated and I thought from the MFA and SSO authentication, it was Secure but i don't have any proof for that one. could you please help me to understand that issue from the SSO login. we have utilized the Basic Auth.

Hi @dharmarajb1 

If you are using Basic Auth from Postman, the SSO and MFA login flow generally will not be involved. Basic Auth directly validates the ServiceNow username and password, so the API user must be active and have the required access.

Please check:

  • The user account is active and not locked.

  • The user has the required roles for the API operation.

  • Basic Authentication is enabled/allowed in the instance.

  • Check System Logs > Security for the exact authentication failure reason.

If your organization requires SSO/MFA for users, it is better to use OAuth 2.0 for integrations instead of Basic Auth.
