Get Started    API Reference

OpenNode sends webhook events to notify your application any time events occur. For example, you can pass a 'callback_url' parameter to check if an invoice is complete. The status will change to 'charge' or 'withdrawal' depending on the type of transaction.

OpenNode offers a webhook simulator tool to help developers test their webhook calls. The tool will simulate a parameter check without having to make an live transaction.
