Managing Webhooks
Webhooks allow you to notify an application, or other external service, when certain events occur in Confluence. For example, you can configure webhooks to update an issue tracker, or trigger notifications in a chat tool.
On this page:
A webhook consists of:
- One or more events – such as page creation, or space removed. You can select multiple events to trigger the webhook.
- A URL – the endpoint where you want Confluence to send the event payloads when a matching event happens.
Once created, Confluence will listen for these events, and send the event payload, in JSON format, to the URL you specified.
Securing the webhook
Confluence uses webhook secrets to authenticate the payload. Combined with HTTPS, it helps ensure the message transmitted is the one that Confluence intended to send, and that the contents were not tampered with.
When you define a secret for a webhook, each request is signed via a Hash-based Message Authentication Code (HMAC). The default for this algorithm is HMACSha256. The header X-Hub-Signature is defined and contains the HMAC.
To authenticate the validity of the message payload, the receiver can perform the HMAC algorithm on the received body with the secret as the key to the HMAC algorithm. If the results don't match, it may indicate there was a problem with transmission that has caused the message payload to change.
Create a new webhook
You need Confluence Administrator or System Administrator global permissions to create a webhook.
To create a new webhook:
- Go to Administration menu
, then General Configuration. >Webhooks. - Enter a title for your webhook.
- Enter the URL of the application or server.
- Enter a secret. This is a string of up to 255 characters that you define.
- Select Test connection to check you can reach the application or server.
- Choose the events that should trigger the webhook.
- Select Active to make your webhook available immediately.
- Select Create.

You can also create a webhook using the API. See Webhooks in the Confluence developer documentation.

Event payloads
Here's an example of the event payload for the page_trashed event. This is the raw data that's sent, in JSON format, to your endpoint.
{
"timestamp":1596182511300,
"event":"page_trashed",
"userKey":"ff80818154ec9913015501e194f601d8",
"page":{
"id":309264476
}
}You'll note that the content is comprised mostly of IDs. This is to ensure that identifiable information is not stored by third party services, or leaked to users who do not have permission to see it.
Once received, you can use the REST API to interpret these IDs. See Confluence Data Center Rest API.
Circuit breaking
To help protect your Confluence site, any webhooks that fail consistently, are skipped for a period of time. By default, if a webhook fails five times, it is considered unhealthy and is skipped, initially for 10 seconds. If it continues to fail, it will be gradually shipped for longer periods, up to 10 hours.
A webhook may also be skipped if there are too many webhooks in flight. If there are 500 webhooks being invoked, further requests will be skipped until the number in flight drops below 500.
