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=your-super-secret-and-long-logflare-key-public&source=62eb0db7-c8ec-465a-9c03-9b4474c6e74b

Or send generic JSON events yourself.

          
    curl -X "POST" "http://localhost:4000/logs/json?source=62eb0db7-c8ec-465a-9c03-9b4474c6e74b" \
         -H 'Content-Type: application/json; charset=utf-8' \
         -H 'X-API-KEY: your-super-secret-and-long-logflare-key-public' \
         -d $'[
      {
        "yellow": true,
        "tags": [
          "popular, tropical, organic"
        ],
        "store": {
          "state": "AZ",
          "city": "Phoenix",
          "zip": 85016,
          "address": "123 W Main St"
        },
        "type": "fruit",
        "name": "banana",
        "qty": 12
      }
    ]'

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=62eb0db7-c8ec-465a-9c03-9b4474c6e74b" \
    -H 'Content-Type: application/json' \
    -H 'X-API-KEY: your-super-secret-and-long-logflare-key-public' \
    -d $'{
      "event_message": "This is another log message.",
      "metadata": {
        "ip_address": "100.100.100.100",
        "request_method": "POST",

Custom Cloudflare Worker

Customize the Cloudflare worker using the template below.

          
    const makeid = length => {
        let text = ""
        const possible = "ABCDEFGHIJKLMNPQRSTUVWXYZ0123456789"
        for (let i = 0; i < length; i += 1) {
            text += possible.charAt(Math.floor(Math.random() * possible.length))
        }
        return text
    }
