Fully managed auth for 1,000+ APIs
Let your users connect any API from your product or agent in a few clicks, and never build, refresh, or store another OAuth token yourself.
What Nango handles
Every auth type covered
OAuth 2.0, OAuth 1.0a, API keys, JWT, Basic auth, and MCP auth; one way to connect across 1,000+ APIs, no matter how the provider does auth.
Drop-in auth UI
Embed Nango's pre-built auth UI and your users authorize in a few clicks with a single SDK call. White-label or fully customize it.

Pre-approved OAuth apps
Nango provides pre-approved OAuth apps so you can connect and start building with zero setup.
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.
Secure credentials
Credentials are encrypted at rest and in transit, with tenant isolation. Credentials never pass through your backend or agent.

FAQ
Yes. Use your own OAuth app, and your users see your brand on the consent screen. You can also use your own callback domain and remove the "Secured by Nango" mention from the Connect UI. Docs (opens in a new tab)
Yes. Nango provides pre-approved OAuth apps for many APIs, letting you build and test right away without waiting on the provider's app review. We recommend switching to your own app before launch for branding, custom scopes, and full control. Docs (opens in a new tab)
Yes. You can set scopes on your integration, and override them per connection when different customers need different access. Docs (opens in a new tab)
Yes. Nango stores and refreshes both Slack's bot and user tokens, and handles the rest of the catalog's quirks too: subdomain-based auth URLs, tenant IDs, regional base URLs, OAuth 1.0a, JWT, and client-credential flows. Each API's docs page lists the gotchas we know about. Slack example (opens in a new tab)
Yes. Set the theme and colors, remove the "Secured by Nango" mention, and point help links to your own docs. If you want full control over every screen, use headless mode and build your own UI on top of Nango's auth. Docs (opens in a new tab)
Yes. Nango refreshes tokens before they expire and at least once a day, so revoked or rotated tokens get caught quickly. You get a webhook when a connection breaks (and when it recovers), and a clear error when you fetch a dead connection, so you can prompt the user to reconnect. Docs (opens in a new tab)
