Passage Connect

Managed account linking — like Plaid, but for any online service.

What is Connect?

Passage Connect lets your users link their accounts from any online service. You create a link, the user authenticates in your app, and you receive the result via webhook. No browser automation code required — Connect handles the session orchestration for you.

How it works

1. Create a link — Your backend calls POST /v1/links with a target provider
2. Present to user — Pass the claim code to the client SDK in your mobile app
3. User authenticates — The user logs in directly in a webview; credentials never leave their device
4. Receive result — Your webhook endpoint receives a signed payload with the account data

Key concepts

• Links — The core abstraction: a lightweight intent to connect an account
• Providers — Supported services (T-Mobile, AT&T, Verizon, and more)
• Webhooks — ES256-signed completion notifications
