How do I provide a valid OAuth/NLAuth authorization header for NetSuite?
Being new to NetSuite and Post Man, I wanted to get my very first RESTlet up and working using Token Based Authentication which I have already set up, therefore I have:
This particular role designated already has Web Services only checkbox ticked as it was indicated in a few guides I followed.
I am currently experimenting tests through my Post Man REST Client by inserting my RESTlet's external URL into the address bar, included the following header keys and their values: (Using the format > Key: Value)
I already replaced the hashes ### with my NetSuite provided information, however anything marked with question marks ??? are generated using php code . (Sensitive information were intentionally removed and left blank on here)
As a result, I received a 403 Forbidden error ("InvalidSignature" on our saved search Login Audit)
Since this is my first RESTlet, I was attempting to display product inventory from NetSuite to products stored on Magento.
In terms of researching done within Magento DevDocs, I have followed DevDocs and created an instance of an Integration API with the intent of being able to link more content to and from NetSuite and Magento in the future.
I admit I am leaving something out unintentionally or have forgotten a step somewhere before here. Any help would much be appreciated.
