Webhooks are the web's way to integrate completely different systems in semi-real time. You can use webhooks on your website to connect with a service that generates invoices when an order is completed, get an alert whenever a new message is received, and more.
To add a webhook:
Go to your website Dashboard.
Click the Settings button.
Select Webhooks from the list.
Click Add a new webhook.
Enter the Webhook URL you want to send your data to.
Choose a Topic for your webhook from the list.
