Acquirer has access to internal payment data but sometimes additional data is required to be sent to the acquirer in certain environments.

To allow the merchant application to provide information to the acquirer library, some constructed fields have been created to pass them in the doPayment API as parameters.

These tags will be persisted in the transaction database, therefore, precaution should be taken in regards to what should be persisted.

Acquirer Proprietary Data

This field serve in both the construction of messages and to parse response.

Retail Sale Data

This field is used to put everything related to the retail environment. It is given directly to the acquirer library for construction of the message.

Original Transaction

This field is used to pass information relating the original transaction in case of transaction related to previous transactions (for example : Cancellation, Pre-Auth Completion, etc.).

It will be overwritten if the original transaction is retrieved from the batch and should only be used when the batch is not used.
