Webhook
Forward notifications to any HTTP endpoint
Send notification payloads to any URL via HTTP POST or PUT. The ultimate escape hatch: integrate with any service that accepts webhooks.
How it works
Configure
Add the channel in your Alphorn dashboard with your credentials.
Send a webhook
POST a JSON payload to your Alphorn webhook endpoint.
Delivered
Alphorn filters, routes, and delivers the notification automatically.
Use cases
- Custom internal service integration
- Zapier / Make / n8n automation triggers
- Data pipeline ingestion endpoints
Configuration
- Target URL
- Custom headers (authentication, content type)
- Full JSON payload forwarding
Send your first notification
One HTTP request is all it takes. Alphorn handles routing to Webhook automatically.
$ curl -X POST https://app.alphorn.dev/n/V1StGXR8_Z5jdHi6B-myT \
-H "Authorization: Bearer $ALPHORN_API_KEY" \
-H "Content-Type: application/json" \
-d '{"title":"Deploy complete","message":"v2.1.0 is live","priority":3,"tags":["deploy"]}'What Alphorn adds on top of Webhook
Wiring Webhook into your application directly is the easy part. What usually grows into a maintenance problem is everything around it: retries when the provider is having a bad day, backoff so you don't get rate-limited, fan-out to additional destinations when a rule fires, and a delivery log for debugging. Alphorn owns all of that on your behalf, so the integration code you write stays at one HTTP call forever.
Every notification is stored in a durable PostgreSQL-backed queue before Alphorn delivers it to Webhook. If delivery fails, Alphorn makes up to five attempts with exponential backoff and records the failure in the delivery log. You can trigger a secondary notification when deliveries to a primary channel fail, for example, page an on-call engineer when a daily summary to a chat room stops going through. Filtering rules based on priority, tags, or JSON path expressions decide at runtime whether a particular payload reaches Webhook or gets routed somewhere else entirely.
The same rules apply whether you're on the managed edition or running Alphorn yourself. The self-hosted edition is AGPL-3.0-or-later and ships as a single container, so you can deploy the exact same delivery pipeline on your own infrastructure, useful for regulated environments where notification data has to stay inside your own network.
