A lightweight HTTP service that logs incoming payloads to the console. Send JSON data via POST requests or query parameters via GET requests, and the service will log all received data with structured output.

Originally created to receive events from Apple Shortcuts and save them to Grafana Loki. Even this is probably overkill for my original needs, but it was a fun little exercise.

go run main.go

The service runs on port 8080 by default.

Run the latest image:

docker run -p 8080:80 ghcr.io/joshhunt/postlog:latest

Or build and run locally:

docker build -t postlog .
docker run -p 8080:80 postlog

• GET /[path] - Log query parameters from any path
• POST /[path] - Log JSON payload from any path (Content-Type: application/json)
• GET /health - Health check endpoint

All requests to any path will be logged with the path included as payload_name and the HTTP method as payload_method.

$ curl "http://localhost:8080/annotation/ac-on?room=bedroom"
