Gyzer Partner Documentation

Welcome to the Gyzer Partner documentation. This site covers the Partner API and widget integration for external partners.

The Gyzer Widget

The Gyzer widget is an embeddable interface that lets your users deposit fiat to receive crypto (USDC, USDT, etc.) and withdraw crypto to fiat. It handles KYC verification (SumSub), wallet management, and bank account linking—all within your app’s flow.

Embed Widget (Pre-Authenticated)

The Embed widget is the recommended integration when you already onboard users. You authenticate them on your side, then call our Partner API to get a short-lived token and embed the widget in an iframe. Users see a seamless deposit/withdraw experience without leaving your app.

How it works:

  1. Your backend calls POST /partners/user-token with the user’s external_user_id, email, and optionally phone.
  2. You receive a token and widget_url (embed URL).
  3. You render an iframe with that URL on your page.
  4. The widget loads, exchanges the token for a session, and shows the deposit/withdraw UI.

For verified US users, if no phone was provided up front, Gyzer collects the US phone number after SumSub KYC is approved and before DTR account creation resumes.

See the Embed Widget Guide for integration steps, or the Widget Installation Guide for the full guide including registration and activation.
