Create a webhook subscription

Create a webhook subscription

post

To start receiving notifications via webhooks, the first step is to create a subscription. A webhook subscription specifies the destination URL for events and defines how they should be filtered. During setup, you can select which events to send to the specified URL. You can create multiple webhook subscriptions to route different types of events to various URLs as needed. Event filters are applied using AND operators, meaning that all specified criteria must be met for an event to be sent. If you want to handle multiple interactionTypes, you’ll need to create separate webhook subscriptions for each.
