Generic Webhook

Use the generic JSON ingest endpoint to generate log events from an external webhook.

e.g. you can set a Github webhook to send events to:

          
http://localhost:4000/logs/json?api_key=8hoCkjbZn-nw&source=c7e5172f-80c8-4823-9b18-8510f5166a59

Or send generic JSON events yourself.

          
    curl -X "POST" "http://localhost:4000/logs/json?source=c7e5172f-80c8-4823-9b18-8510f5166a59" \

Custom API Request

Send logs via an HTTP request. This request body payload lets you send over a human readable event message in the message field.

          
    curl -X "POST" "http://localhost:4000/logs?source=c7e5172f-80c8-4823-9b18-8510f5166a59" \
