Twinfield (Sage) cloud accounting platform.

oauth_credentials

Twinfield

Twinfield itself has no sandbox/production selector — one OAuth client ID and one set of credentials serve both testing and live use. The only change at go-live is on the Apideck side: swap Apideck's own credentials (uncertified, development and testing only) for your certified client ID. Testing always targets a real Twinfield administration rather than an isolated mock, so writes post real transactions.
