Webhook events and payloads
You can create webhooks that subscribe to the events listed on this page. To limit the number of HTTP requests to your server, you should only subscribe to the specific events that you plan on handling. For more information, see "Creating webhooks."
Each webhook event on this page includes a description of the webhook properties for that event. If the event has multiple actions, the properties corresponding to each action are included.
Each event is only available to specific types of webhooks. For example, an organization webhook can subscribe to the team event, but a repository webhook cannot. The description of each webhook event lists the availability for that event. For more information, see "Types of webhooks."
Payloads are capped at 25 MB. If an event generates a larger payload, GitHub will not deliver a payload for that webhook event. This may happen, for example, on a create event if many branches or tags are pushed at once. We suggest monitoring your payload size to ensure delivery.
You can choose to have payloads delivered in JSON format (application/json) or as URL-encoded data (x-www-form-urlencoded). Following is an example of a webhook POST request that uses the JSON format.
