Introducing SlackPipes: One Webhook, Any Channel

by SlackPipes Team

Slack’s incoming webhooks are a powerful way to send automated messages to your workspace. But they come with a frustrating limitation: each webhook URL can only post to a single channel.

If you’re building integrations that need to post to multiple channels—alerts to #ops, deploys to #engineering, updates to #general—you end up juggling dozens of webhook URLs. It’s a configuration nightmare.

The Problem

Consider a typical CI/CD pipeline. You might want to:

  • Post build failures to #engineering
  • Post deploy notifications to #releases
  • Post security alerts to #security
  • Post customer-facing updates to #general

With standard Slack webhooks, that’s four different URLs to manage, rotate, and keep track of. Multiply that across different environments and services, and you’re drowning in webhook management.

The Solution

SlackPipes gives you a single webhook endpoint that can route messages to any channel in your workspace. Just specify the channel in your request:

# Post to #alerts (channel in URL path)
curl -X POST https://api.slackpipes.com/hook/abc123/alerts \
  -H "Content-Type: application/json" \
  -d '{"text": "Server CPU at 95%"}'

# Post to #engineering (plain channel name in request body)
curl -X POST https://api.slackpipes.com/hook/abc123 \
  -H "Content-Type: application/json" \
  -d '{"channel": "engineering", "text": "Build #1234 passed"}'

You can specify the channel in multiple ways:

  • URL path: /hook/abc123/channel-name
  • Header: X-SlackPipes-Channel: channel-name
  • Request body: {"channel": "channel-name", "text": "..."}

Just use the plain English channel name—like alerts or engineering—no need to look up cryptic channel IDs.

Built for Reliability

We’ve built SlackPipes on Cloudflare’s edge network, which means:

  • Low latency: Requests are processed at the edge, close to your servers
  • Rate limit handling: We queue messages and handle Slack’s rate limits with automatic retry and backoff
  • Request logging: Full visibility into every request—see what was sent, when, and whether it succeeded

Get Started

SlackPipes is now in public beta. The free tier includes 1,000 messages per month—plenty to try it out.
