Message statuses allow you to see if your message has delivered successfully. If you are using WhatsApp via our API, you will need to make sure you are set up correctly in order to receive message statuses. You can quickly do so in the following three steps:

1. Set up a webhook that subscribes to the message.updated events
2. Include the reportURL as a parameter in your API requests
3. Status updates will be sent via a POST request to your URL
