The payment ID is a 30-character unique identifier for each payment. It follows the form pay_ and 26 alphanumeric characters. When you're contacting Checkout.com for support on specific payments, providing the payment ID can help locate and troubleshoot the payment quickly.
You can find the payment ID in the Payments section of your Dashboard, in the API response, or in the payment webhooks.
In the Dashboard
To find the payment ID:
-
Sign in to the Dashboard.
-
Go to Payments > Processing > All Payments.
-
Select the payment for which you need the payment ID. You can view the payment ID in the Payment details page that opens.
Using the API
When you request a payment using the Request a payment or payout endpoint, the payment ID is included in the response if the status code is 201 or 202.
Using the webhooks
If you have webhooks configured for payment events, you receive the payment_pending webhook when a payment is successfully initiated. You can find the payment ID in the data.id field.
