The Dock platform makes it easy to process compensation and settlement for customers by enabling the Clearing outgoing file that is generated after matching transactions. It eliminates complexity in integrations with card brands and creditors.

You can use this file when issuers don’t carry out the entire processing through Dock services and where we serve as an intermediate party in processing authorization and Clearing with card brands.

How clearing works?


In order to generate a clearing file, you need to make a transaction, so you need to have cards previously registered.

1 - When a transaction happens, the authorizer while validating it stores the data in a data lake, which can be used later for clearing purposes.

2 - When a transaction ends, the card brand lets the clearing file available for Dock;

3 - Dock matches the clearing file received from the card brand with the authorization’s information that is stored in the data lake (step 7 from stage 1), generates the clearing file in JSON format and provides it for the issuer.

4 - The issuer receives the clearing file sent by Dock and takes action after interpreting the field Action Code, sent in the file. Click here to get more details on the Action Code and other fields in the file.

Types of layouts

The clearing process has two different types of layouts:

  • Transactional JSON: it sends to the issuer all financial transactions that have a direct impact on the issuer's portfolio.

  • Write-off file: it tracks the term of the authorized transaction, then informs the issuer that a specific transaction was not confirmed by the clearing file and after a previously parameterized period it ends up being inserted in this file. It allows the transaction to be "canceled" by the issuer, releasing the limit of the cardholder.
