Developers — SDKs
Pick the integration surface that fits your team's timeline. Hosted flow ships this week; native SDKs give you chip reads and full control of the UI.
Integration surfaces
All four write to the same audit trail and emit the same webhook events.
Client libraries
Minimum OS versions, bundle sizes, and plugin availability are shared with the SDK download.
Web example
The client never sees an API key. Your server creates the session and mints a short-lived token scoped to that session only.
Never trust the client callback as the decision. Treat onComplete as a navigation signal, and confirm the outcome from the webhook plus an authenticated read.
Sandbox keys include seeded subjects for every outcome, so you can build the unhappy paths before you have real traffic.
