# Payment Binding

> Binding-based payments for recurring transactions and saved payment method workflows.

<Info>
  This feature is exclusive to a select number of partners on demand.
</Info>

Flouci Advanced APIs allow merchants to create **binding-based payment flows** where customers link their Flouci account or saved card once, then pay with a single tap on subsequent transactions — no redirects except for 3DS, no re-entering credentials.

## How it works

<Steps>
  <Step title="Create a binding">
    Make a first payment with a unique `client_id`. The customer completes checkout normally, and their payment method is saved for future use. See [Create Binding](/api-reference/advanced-payment-flow/create-binding).
  </Step>

  <Step title="Pay with the binding">
    For subsequent transactions, send the `binding_id`, `client_id`, and `cvc` along with the payment amount. No checkout redirect needed (except for 3DS). See [Pay with Binding](/api-reference/advanced-payment-flow/confirm-binding).
  </Step>

  <Step title="Verify the payment">
    Use the standard [Verify Payment](/api-reference/verify-transaction) endpoint to confirm the transaction status.
  </Step>
</Steps>
