OAuth 2.0 Client Credentials Flow - POST Request to the Token Endpoint and the Access Token Response

edited Jun 2, 2025 2:30PM in Ask A Guru 14 comments

Hi All,

I need help as I've been at this for a number of days. I'm trying to setup OAuth2.0 Client Credentials Flow in order to access a NetSuite Restlet from a third party application. I'm using javascript in the third party application. I've been able to manage to get it working in Postman but not from the app. I've setup the integration record specifically for M2M integration using Restlets. I've also created the Client Credentials and setup for my user as well as adding the certificate generated using openssl req -x509 -newkey rsa:4096 -sha256 -keyout auth-key.pem -out auth-cert.pem -nodes -days 730.
