# Clink Official Docs Export

## Quickstart

Clink supports merchant standard integration and merchant agent integration.

## Integration

Merchant standard integration covers checkout session creation, webhook handling, and refund synchronization.

Merchant agent integration covers `POST /order/payment-session`, `GET /order/payment-session/{sessionId}`, and `WEBHOOK customer.verify`.

## Checkout Session

Use `/checkout/session` to create a checkout session.

## Refund

Refunds are modeled as a lifecycle. The current public docs confirm querying refund details through `GET /refund/{id}`.

No public refund-create API is confirmed in this docs export.

## Webhooks

Webhook implementations should verify `X-Clink-Timestamp` and `X-Clink-Signature`, and must tolerate retries and out-of-order delivery.
