Overview | Receiving API Call

Notification Service


The “Notification Service” is a service, that automatically updates you about the latest status of your transactions (typically every 5 minutes). Like mentioned before, it is the only service, in which you receive an api call from helloPay, why you need the callback url. The callback url doesn’t need a UI (user interface), it just needs to be able to accept api calls in JSON format and work with the results.
