About webhook events and payloads

You can create webhooks that subscribe to the events listed on this page. 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. For more information, see "AUTOTITLE."

Delivery headers

HTTP POST payloads that are delivered to your webhook's configured URL endpoint will contain several special headers:

• X-GitHub-Event: Name of the event that triggered the delivery.
• X-GitHub-Delivery: A GUID to identify the delivery.{% ifversion ghes or ghae %}
• X-GitHub-Enterprise-Version: The version of the {% data variables.product.prodname_ghe_server %} instance that sent the HTTP POST payload.
• X-GitHub-Enterprise-Host: The hostname of the {% data variables.product.prodname_ghe_server %} instance that sent the HTTP POST payload.{% endif %}{% ifversion not ghae %}
• X-Hub-Signature: This header is sent if the webhook is configured with a secret. This is the HMAC hex digest of the request body, and is generated using the SHA-1 hash function and the secret as the HMAC key.{% ifversion fpt or ghes or ghec %} X-Hub-Signature is provided for compatibility with existing integrations, and we recommend that you use the more secure X-Hub-Signature-256 instead.{% endif %}{% endif %}
• X-Hub-Signature-256: This header is sent if the webhook is configured with a secret. This is the HMAC hex digest of the request body, and is generated using the SHA-256 hash function and the secret as the HMAC key.
• User-Agent: This header will always have the prefix GitHub-Hookshot/.

To see what each header might look like in a webhook payload, see "Example webhook delivery."

Example webhook 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.
