Besides the MplusKASSA API, there is another method to extend the MplusKASSA software with additional functionality. We have dubbed this system Webhooks. Using this system, you can create a web-based application that reacts to various events occuring in our software. You can use this to do things like applying vouchers, registering ticket sales or triggering other actions.

In this section you will find a technical explanation of this system and request and response examples for all the different events that are supported by Webhooks.

When you are ready to start development, you can request to become a Partner to receive a license for the MplusKASSA software with webhook functionality.
