That looks like the correct request body. Have you double checked the configuration? The only way to get an unauthorized error is when something is misconfigured. :slight_smile:

I am repeatedly getting the exact same error. And the interesting thing is that a direct curl call works.

I am having trouble pasting my sample code here (getting a 403 error from the dev forum itself when I try to post). Will keep trying…

See here for my sample apps that show success with curl vs failure with nodejs:

Oops – my issue (which is different from the original poster’s issue) is that my call to new SquareClient(), I was passing accessToken: ... when I should have passed token: ...
