Transaction workflows

Transaction workflows

Please note that not all transaction types are supported for each payment method/acquirer. Make sure that the transactions and workflows you are planning to use are supported by the payment method and acquirer of your choice.

This guide serves only as a reference for all supported transactions and workflows. For details on each transaction type and/or operation, please refer to the respective detailed tutorials.

We can divide the transactions into three groups:

Initial transactions

These transactions can be the first in the workflow. They can be sent without referencing a previous transaction, but they all can be followed up by another transaction.

Registration/Tokenization (RG)


With tokenization the card data will be stored and can be re-used in later transactions.

How to use it:

Depending on your integration, there are multiple ways to create tokens. Follow the tokenization guide for more information.
