hookpipe

Reliable webhook infrastructure for AI agents. Receive webhooks from Stripe, GitHub, Slack, Shopify, Vercel with signature verification, durable queuing, and automatic retries. Use when: (1) setting up webhook listeners for external services, (2) agent needs real-time events from Stripe/GitHub/Slack, (3) webhooks are being lost during restarts or downtime, (4) need durable event buffering with guaranteed delivery. NOT for: sending outgoing webhooks to customers (use Svix), direct API polling, or cron-based scheduled checks.

hookpipe — Webhook Infrastructure for AI Agents

hookpipe receives webhooks from external services, queues them durably, and delivers them to your agent with automatic retries. Your agent never misses an event, even during restarts or downtime.

Why Use This

Without hookpipe, webhooks sent while your OpenClaw gateway is restarting or offline are lost forever. Most providers send once and move on. hookpipe sits in between — it's always online (Cloudflare Workers, 300+ edge locations), accepts the webhook immediately, and retries delivery to your gateway until it succeeds.

Quick Start

Local development (receive webhooks on your machine)

bash

hookpipe dev --port 18789 --provider stripe --secret whsec_xxx

This creates a secure tunnel to your OpenClaw gateway. Paste the printed Webhook URL into your Stripe Dashboard. No port forwarding, no IP exposure.

Production setup (persistent, survives restarts)

bash

# 1. Deploy hookpipe (one-click on Cloudflare, or self-host)
# 2. Configure CLI
hookpipe config set api_url https://your-hookpipe.workers.dev
hookpipe config set token hf_sk_xxx

# 3. Connect a provider to your OpenClaw gateway
hookpipe connect stripe \
  --secret whsec_xxx \
  --to http://localhost:18789/webhook \
  --events "payment_intent.*"

hookpipe returns a Webhook URL — register it in Stripe's dashboard. Events are now durably queued and delivered to your gateway with retries.

Built-in Providers

bash

hookpipe providers ls

Provider	Events	Use case
stripe	payment_intent, customer, invoice, charge	Payment notifications
github	push, pull_request, issues, release	Code events, PR review
slack	message, app_mention, reaction	Team notifications
shopify	orders, products, customers	E-commerce events
vercel	deployment, domain	Deploy monitoring

Discover a provider's events:

bash

hookpipe providers describe stripe --json

Any other webhook service

Not limited to the 5 built-in providers. For any service already sending webhooks to your agent, use generic HMAC verification:

bash

hookpipe connect my-service --secret my_signing_secret --to http://localhost:18789/webhook

For services with non-standard signature formats, the community can create custom providers with defineProvider() — a single file that defines verification method, event types, and payload schemas. See Provider Design Guide.

Core Workflows

Stripe payment alerts

bash

hookpipe connect stripe --secret whsec_xxx --to http://localhost:18789/webhook --events "payment_intent.payment_failed"

Agent receives failed payment events and can draft follow-up emails, create support tickets, or alert the team.

GitHub PR auto-review

bash

hookpipe connect github --secret ghsec_xxx --to http://localhost:18789/webhook --events "pull_request"

Agent receives PR events instantly and can review code, post comments, or run checks.

Multi-provider monitoring

bash

hookpipe connect stripe --secret whsec_xxx --to http://localhost:18789/webhook --name stripe-prod
hookpipe connect github --secret ghsec_xxx --to http://localhost:18789/webhook --name github-prod
hookpipe connect vercel --secret vsec_xxx --to http://localhost:18789/webhook --name vercel-prod

All events flow to your gateway through one durable pipeline. Restart your gateway freely — nothing is lost.

Monitor events in real-time

bash

hookpipe tail --json

Stream events as they arrive. Pipe to scripts or other agents:

bash

hookpipe tail --json | jq '.event_type'

What Happens During Downtime

text

Your gateway goes down at 2:00 AM
  ↓
Stripe sends payment_intent.succeeded at 2:15 AM
  → hookpipe accepts (202), queues durably
  ↓
GitHub sends push at 2:30 AM
  → hookpipe accepts (202), queues durably
  ↓
hookpipe retries delivery every few minutes (exponential backoff)
  ↓
Your gateway comes back at 6:00 AM
  → hookpipe delivers both events automatically
  → Agent processes them as if nothing happened

No manual replay needed. No events lost. Circuit breaker protects your gateway from being overwhelmed on recovery.

CLI Reference

bash

hookpipe connect <provider> --secret <s> --to <url> [--events <filter>]
hookpipe dev --port <n> [--provider <name>] [--secret <s>]
hookpipe providers ls [--json]
hookpipe providers describe <name> [--json]
hookpipe tail [--json] [--source <id>]
hookpipe events ls [--json] [--limit <n>]
hookpipe health [--json]

All commands support --json for structured output and --dry-run for validation.
