I’m trying to setup the Oauth 2.0 authentication Machine to machine in Postman to get an access token for Netsuite.
Postman => Netsuite
I already have created TBA (Oauth 1.0) issue token endpoint and 3ways flow.
I also already have created code that were using Oauth 2.0 Authorization code grant flow.
But this time I can’t manage to successfully get the access token
