6Storage.com Xero Integration

6Storage.com Xero Integration


We're trying to integrate 6Storage.com with Xero.

Whenever we get to the part after entering in a client ID and password (freshly generated from an Administrator, but we also tried from a Standard user), we get this error message when the login window pops up:

Error code: 500
Error: unauthorized_client : Invalid redirect_uri

We have carefully entered everything as the article indicates. Is the article out of date, or are there any troubleshooting steps/suggestions?
