Key not found

HTTP 401   key_not_found

What it means

TxGold doesn't know the key in TxG-Key-Id, or it belongs to the other environment (Sandbox and Production keys are separate).

What to do

Check that you're using the key file for this environment, and that the key is still listed for the integration in the business portal.

The response

Branch on code, never on title or detail: the code never changes once published, and the text may. Quote requestId to TxGold support. See all errors.
