OpenNode sends webhook events to notify your application any time there is an update to your charges or withdrawals.
For example, you can specify a
callback_url parameter when creating a charge and OpenNode will send you webhook events for any update regarding that charge - e.g. the charge was successfully paid.
OpenNode offers a webhook simulator tool to helps developers test their webhook handling. The tool will simulate a parameter check without having to make a real transaction.
Simulating a failed withdrawal event.
You can simulate all possible charge events with the webhook simulator.
