Pre-approved OAuth apps

Nango provides pre-approved OAuth apps so you can connect and start building with zero setup.

Pre-approved apps

Tokens stay valid

Users authorize once and Nango manages OAuth token refreshes. No cron jobs, no expired-token incidents.

API quirks, handled

Every provider API has its own parameters, values, and undocumented quirks. Nango keeps them all current as providers change.
