Getting "invalid_grant" when hitting token endpoint.

edited Jun 2, 2025 2:25PM in Ask A Guru 5 comments

I'm following this article https://chamilelle.medium.com/setup-rest-web-service-and-oauth-2-0-in-your-netsuite-account-c4243240bc3f which explains how to get access token for NetSuite OAuth 2.0 using Postman.

When I make a POST req to the token endpoint, I get an error of invalid_grant.

Can you please tell me the reason and possible solution. Thank You !
