Introduction

Gate partner sessions, embeds, rails, and webhooks.

Gate lets a partner create a server-bound crypto buy or sell session and hand the browser a restricted client secret. The hosted widget collects user inputs and calls Gate on the partner's behalf; signed webhooks report lifecycle and settlement events back to the partner server.

Integration surfaces

• Hosted widget: create POST /gate_sessions on your server, then mount the iframe with pk_* and the returned client_secret.
• Partner API: discover capabilities, preview quotes, reconcile sessions and transactions, manage customers and branding, and operate entitled fiat rails.
• Partner dashboard: read Gate usage and volume, configure webhooks, rotate the signing secret, inspect deliveries, and replay dead letters.
• Webhooks: receive signed session, KYC-required, quota, rail, quote, customer, and test events.

The public Gate API is unversioned. Partner endpoints do not include staff/operator functions. The current Gate release has no swap runtime; its future prefunded Bitget swapper is a separately planned product surface.

Availability is partner-, mode-, country-, currency-, and entitlement-specific. Always query /capabilities/* and /capabilities/eligibility rather than relying on a static corridor list.

Start with the quickstart, then read authentication and webhooks.
