Xero API Call 401 Error

I’m using the make api call module for Xero and I’m able to make a call to some endpoints but for others, I’m getting a 401 “Unauthorized” error.

For example I’m trying to get /2.0/Journals. Looking at the documentation, I don’t see anything that should be preventing this (Accounting API Journals — Xero Developer) . Any ideas?

What is the authentication method? Are you on a paid Xero account? Have you tried redoing your Xero connection in a make? Have you tried to make the call directly with postman or http app?

So many troubleshooting steps that can be taken. Try to eliminate make out of the situation to confirm your credentials give you access to the endpoints you want to use.
