Calling Okta Rest Service in Postman using Oauth 2.0 service app

Hi Team,

I want to call the Okta Rest service using Oauth 2.0 service app

I created the service application in Okta and have configured Oauth2.0 as Authorization method but I am getting the below error.

Clients with ‘application_type’ of ‘service’ are not allowed to access the ‘authorize’ endpoint

Could anyone please let me know if we can using Oauth 2.0 service app to create a token and create user using postman okta rest api?

To get a token for “service”, you need to call /token endpoint directly presenting authorization header from client_id/secret.
