A Retrieval Reference Number (RRN) is a unique identifier assigned to a card transaction during the authorization stage.
You can find the RRN in the Payments section of your Dashboard, in the API response, or in the payment webhooks.
In the Dashboard
To find the authorization RRN:
- Sign in to the Dashboard.
- Go to Payments > Processing > All Payments.
- Select the payment for which you need the authorizaton code.
- In the Payment timeline section, expand the Authorization step.
The RRN is displayed. If instead you only see an Acquirer Reference Number (ARN), you can use this as the RRN value. For some schemes, the RRN and ARN values are equivalent.
Using the API
You can find the RRN using the Get payment details endpoint in the API. It is returned in the processing.``retrieval_reference_number field.
Using the webhooks
If you have webhooks configured for payment events, you can find the authorization code in the auth_code field of the payment_approved webhook.
The RRN is a card scheme level tracking number. Standard customer service representatives for banks usually cannot search for it. Inform your customer that when they contact their bank, they should ask to be transferred to the Disputes or Electronic Funds department. They should have the access required to trace the RRN.
