Webhook fan-out: when one endpoint is not enough
Webhook fan-out: when one endpoint is not enough
Most products start with one webhook endpoint. A payment provider, form tool, repository host, or internal service sends events to a single URL, and your app reacts. That works until the same event needs to reach more than one place. Billing wants it, analytics wants it, support wants it, and your debug log wants the raw payload.
Webhook fan-out is the pattern of receiving one inbound event and forwarding it to multiple destinations. Instead of asking the provider for more webhook slots, you put one stable URL in front of it and manage the destinations yourself.
What good fan-out needs
A reliable fan-out layer should capture the raw request, redact sensitive headers, forward to each destination independently, retry failures, and make the result visible. The important part is independence: a slow Slack endpoint should not stop your billing handler from receiving the same event.
When it helps
Use fan-out when you need production plus staging mirrors, Slack or Discord alerts, warehouse ingestion, incident debugging, or temporary handoffs during a migration. It is also useful when a provider only offers one endpoint but your workflow has several consumers.
Why Behose exists
Behose gives every project a hose URL, records what arrived, and forwards each request to the destinations you choose. You can start with no account, inspect deliveries live, and add retries without rewriting your app.
The rule is simple: keep the provider pointed at one durable URL, then change destinations behind it whenever your workflow changes.
