Usage overview

Webhooks are a way to proactively subscribe to events that occur in your KnowledgeOwl account. When an event occurs that you have subscribed to, we will POST a message to the endpoint of your specification containing information about the event.

Currently we offer 2 types of POST payloads, one formatted specifically for the application Slack, and the other containing KnowledgeOwl API object data.

Create a new webhook subscription:

Before you attempt to create a new webhoook, make sure you have an endpoint that is ready to receive information and will return an HTTP status code of 200.

During the subscription creation, a test call will be made to your endpoint. If the endpoint you specify does not return an HTTP status code of 200, your webhook subscription will not be created.

JSON object sent during test call to provided endpoint when the output is set to "default":


Single event:

curl -u {{API key}}:x -H "Content-Type: application/json" -X POST -d
'{"event": "article.delete", "endpoint": "https://hooks.slack.com/services/abcdefe123/abcd1234", "output": "slack"}'
