Hey team - would really really love some help on something I’ve been stuck on for 3 hours.
I’m trying to do the OAuth2 exchange the code call (link).
This is how I’ve set it up, and this is the error I’ve got. I have Base64 encoded by client id:client secret. The redirect_uri matches. I have gone through the Xero auth and got the “code” I think in the right way (see image)… I have no idea why I can’t get this to initalise… any help would be so appreciated.
