Advice messages (webhooks)

Advice messages is a new value-added service that merchants can optionally configure if their backend system benefits from such notifications (XML requests).

Those XML messages refer to manual actions that can be performed upon a transaction through Back Office tool.

The manual actions through Back Office tool for which a respective message can be sent to the merchant are Capture of preauth, Void, Refund and Cancel recurring.

Moreover, advice message can also be sent for initial payment transaction and recurring child.

Primarily, it is mandatory to choose the XML version that e-commerce platform shall use for the XML message sent.
If merchant’s implementation for VPOS requests is based on digest calculation, then 2.1 should be chosen.
If merchant’s implementation for VPOS requests is based on signature calculation, then 4.1 could be chosen. If version 4.1 has been chosen, then the processor certificate should be used for the message validation.
Depending on the events a merchant needs to receive advice messages for, the respective value is filled in with the URL(s) that shall receive that message. Multiple URLs (up to 5) can be configured for each advice, separated with new line ‘\n’.
If one advice is left blank, then no message will be sent for that action.
It is also possible to configure retry options. If first sending fails (network error, not http 200), then after selected seconds, service will re-post the original advice message.
