I'd like to create my custom Xero app, but unfortunately, user can not authorize in it. I use this guide
When user opens authorization link like that:
https://login.xero.com/identity/connect/authorize?response_type=code&client_id=EC5X0XXXXXXC43BXXXXXXX08CC77741&redirect_uri=https://service.com/finish&scope=openid profile email accounting.transactions&state=123
an error appears
"unauthorized_client : Unknown client or client not enabled"
How could I fix this issue?
