Source ID

You'll need this source ID for some integrations or libraries.

ebb907b3-05f8-480d-99ea-faf54ca60051

If you're hosted on Vercel setup our Vercel integration!

Install the Vercel integration

Gigalixir

Install the Gigalixir command line tool, and navigate to your project directory.

          
    gigalixir drains:add "http://localhost:4000/logs/logplex?api_key=8hoCkjbZn-nw&source=ebb907b3-05f8-480d-99ea-faf54ca60051"

Cloudflare App

Install the agent

Javascript

Use our official Pino transport to send log events from your Javascript project.

Setup the Pino transport

Github Webhook

Set your Github webhook to this Logflare endpoint and we'll ingest Github webhooks for you. This endpoint drops all keys ending in _url so it keeps your Github payloads in check.

        
http://localhost:4000/logs/github?api_key=8hoCkjbZn-nw&source=ebb907b3-05f8-480d-99ea-faf54ca60051

Github Action

Use our Github Action (thanks @gr2m) to easily log events coming from your repositories.

Setup the Github Action

Fluent Bit

Watch log files on a server with this Fluent Bit output config.

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=ebb907b3-05f8-480d-99ea-faf54ca60051

Or send generic JSON events yourself.

          
    curl -X "POST" "http://localhost:4000/logs/json?source=ebb907b3-05f8-480d-99ea-faf54ca60051" \
         -H 'Content-Type: application/json; charset=utf-8' \

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=ebb907b3-05f8-480d-99ea-faf54ca60051" \
