Incoming and Outgoing Payment Messages
This feature is scheduled for deprecation. We recommend contacting Mambu Support to discuss alternative options.
The Mambu Payment Gateway groups information about payment messages under two menu items, Incoming and Outgoing.
The Incoming menu item contains information about incoming payment messages. This includes all the pending payment messages as well as the those that have already been processed by the scheduler.
Payment messages
Pending payments
For both incoming and outgoing payment messages, the payment message will first enter the pending state and once the scheduler runs if will move to the list of processed payment messages. For more information about schedulers, see Schedulers.
Payment message detail screen
In any list of payment messages, you may select a payment message to view the payment message detail screen. Here you can see more detailed information about the SEPA message (XML).
In the table we provide a list of the fields in the XML.

Incoming / Outgoing
The incoming / outgoing menus are used to monitor received/sent payment messages. When clicking this menu, the user is prompted with two sub-menus:
- SEPA
- Alerts
The sub-menu SEPA gives users a view on the incoming / outgoing SEPA messages:

Transactions List
Each row represents one of the following SEPA messages:
- Pacs.008
- Pacs.004
- Pacs.002
- Camt.056
- Camt.029
The list provides the following information on a message:
- System ID
- Message type
- Message ID
- Number of transactions inside a given message
- Settlement date
Clicking a single row will provide users more information on the payment message:
- Transaction number
- Message ID
- Status
- Amount
- Creditor IBAN

By clicking on the arrow of each row the SEPA message (xml) will be seen in full on the detail screen.
For more information about these messages, please refer to the 2019 SEPA Credit Transfer rulebook version 1.2 which you can find at the website of the [European Payments Council](https://www.europeanpaymentscouncil.eu/
The fields displayed are relevant for the end users and provide useful information in case of investigation or customer requests.

| Execution date | Date at which the order is really executed. Requested and real execution dates are the same most of the time. |
