End-user guide to authorize the integration and start using GoCardless actions. Access tokens are for using your own GoCardless account with the API. To build a partner integration that manages other users' accounts, use OAuth 2.0 instead. Tokens are environment-specific — a sandbox token only works with the Sandbox environment and a live token only with Production.
