Payment Sessions

Capture a payment session

Changed on

Captures authorized funds. The session must have a positive capturable balance and the captureExpiresAt deadline must not have passed.

This is an asynchronous operation. The capture is returned in pending status and transitions to succeeded or failed.

Multiple partial captures are allowed. If amount is omitted, the full remaining capturable amount is captured.

Request

  • Base URL: https://api.cdp.coinbase.com/platform
  • URL: https://api.cdp.coinbase.com/platform/v2/payment-sessions/{paymentSessionId}/captures
  • Auth: HTTP bearer

Path parameters

paymentSessionIdstring required

The ID of the payment session, a UUID prefixed by paymentSession_.

Example:paymentSession_82c879c1-84e1-44ed-a8c2-1ac239cf09ad

The unique identifier of the payment session.

Headers

X-Idempotency-Keystring

An optional string request header for making requests safely retryable. When included, duplicate requests with the same key will return identical responses. Refer to our Idempotency docs for more information on using idempotency keys.

Request body

amountstring

A decimal representation of the amount to capture, denominated in the session's asset. If omitted, the full remaining capturable amount is captured.

finalCaptureboolean required

When true, this capture is treated as the final one for the authorization. Any remaining capturable balance is released back to the payer immediately after the capture settles. When false, the remaining capturable balance stays held and is available for subsequent partial captures (subject to captureExpiresAt). Has no effect if amount equals the full capturable balance, since no remaining balance exists to release.

metadataMetadata

Optional metadata as key-value pairs. Use this to store additional structured information on a resource, such as customer IDs, order references, or any application-specific data. Up to 10 key/value pairs may be provided. Keys and values are both strings. Keys must be ≤ 40 characters; values must be ≤ 500 characters.

externalReferenceIdstring

A merchant-provided internal identifier for a resource from the merchant's own system—not visible to the payer. It must not contain personally identifiable information (PII) or payment credentials.

Example request

{
  "amount": "1.00",
  "finalCapture": true
}

Successfully created capture.

captureIdstring

amountstring

When false, the remaining capturable balance stays held and is available for subsequent partial captures (subject to captureExpiresAt). Has no effect if amount equals the full capturable balance, since no remaining balance exists to release.
