Hookaido Webhook Integration

Webhook infrastructure for receiving, queuing, and delivering webhooks. Operate Hookaido webhook ingress, durable webhook queue (SQLite/Postgres), webhook delivery (HTTP push, subprocess exec, pull API, SSE streaming), webhook signature verification (HMAC, GitHub, Gitea, Stripe, Cituro), dead-letter queue, and webhook retry policies. Use when tasks involve webhook endpoint configuration (Hookaidofile), webhook queue backends (sqlite, memory, postgres), hookaido CLI (run, config fmt, config validate, mcp serve), webhook consumption (dequeue/ack/nack/extend) over HTTP, SSE, or gRPC, subprocess webhook handlers (deliver exec), webhook provider HMAC (GitHub/Gitea/Stripe/Cituro), Admin API webhook backlog/DLQ triage, or production webhook hardening.

Hookaido

Overview

Implement and troubleshoot Hookaido with a config-first workflow: edit Hookaidofile, validate, run, exercise ingress/pull/exec flows, then diagnose queue health and DLQ behavior. Treat Hookaido v2.6.0's modular architecture as additive in this skill: keep the existing workflow intact by default, and opt into modules such as postgres, gRPC workers, subprocess delivery (deliver exec), or release verification only when they materially help the task. Use conservative, reversible changes and validate before runtime operations.

Workflow

1. Confirm target topology: inbound+pull (HTTP or gRPC), push outbound, subprocess exec, or internal queue, plus the queue backend (sqlite, memory, or postgres).
2. Choose runtime mode and ensure hookaido exists where tools execute.
   • Host-binary mode: use the install action from metadata.openclaw.install.
   • Host fallback: run bash {baseDir}/scripts/install_hookaido.sh (pinned v2.6.0, SHA256-verified).
   • Public repo/source mode: use the public upstream repo github.com/nuetzliches/hookaido via go install github.com/nuetzliches/hookaido/cmd/hookaido@v2.6.0 when a source-based install is preferred.
   • Docker-sandbox mode: use a sandbox image that already includes hookaido (preferred), or install inside sandbox via agents.defaults.sandbox.docker.setupCommand.
   • Keep host install actions available as fallback and to satisfy metadata.openclaw.requires.bins.
3. Inspect and update Hookaidofile minimally.
4. Run format and validation before starting or reloading:
   • hookaido config fmt --config ./Hookaidofile
   • hookaido config validate --config ./Hookaidofile
   • hookaido config validate --config ./Hookaidofile --strict-secrets when secret refs or Vault-backed config are involved.
5. Start runtime and verify health:
   • hookaido run --config ./Hookaidofile --db ./.data/hookaido.db
   • hookaido run --config ./Hookaidofile --postgres-dsn "$HOOKAIDO_POSTGRES_DSN" when queue postgres is selected.
   • curl http://127.0.0.1:2019/healthz?details=1
6. Validate end-to-end behavior:
   • ingress request accepted and queued
   • consumer dequeue/ack/nack/extend path works (HTTP pull, batch ack/nack, plus gRPC pull when enabled)
7. For incidents, inspect backlog and DLQ first, then mutate.

Task Playbooks

Configure Ingress and Pull Consumption

1. Define a route with explicit auth and pull path (HTTP pull, optional gRPC pull worker listener).
2. Keep secrets in env/file refs, never inline.
3. Verify route and global pull auth are consistent.
4. Test with a real webhook payload and a dequeue/ack cycle, using batch ack/nack when worker throughput matters.

Prefer this baseline:

hcl

ingress {
  listen :8080
}

pull_api {
  listen :9443
  grpc_listen :9943 # optional gRPC pull-worker listener
  auth token env:HOOKAIDO_PULL_TOKEN
}

/webhooks/github {
  auth hmac env:HOOKAIDO_INGRESS_SECRET
  pull { path /pull/github }
}

Configure Push Delivery

1. Use push delivery only when inbound connectivity to the service is acceptable.
2. Set timeout and retry policy explicitly.
3. Validate downstream idempotency since delivery is at-least-once.

hcl

/webhooks/stripe {
  auth hmac env:STRIPE_SIGNING_SECRET
  deliver "https://billing.internal/stripe" {
    retry exponential max 8 base 2s cap 2m jitter 0.2
    timeout 10s
  }
}

Configure Subprocess Delivery (deliver exec)

1. Use exec delivery when the target is a local script or binary, not an HTTP service.
2. Payload is piped to stdin; metadata arrives as env vars (HOOKAIDO_ROUTE, HOOKAIDO_EVENT_ID, HOOKAIDO_ATTEMPT, etc.).
3. Exit code determines retry behavior: 0 = ack, 1-125 = retry, 126/127 = immediate DLQ.
4. sign directives are not supported with exec (compile error).

hcl

/webhooks/github {
  auth hmac {
    provider github
    secret env:GITHUB_WEBHOOK_SECRET
  }
  deliver exec "/opt/hooks/deploy.sh" {
    timeout 30s
    retry exponential max 3 base 1s cap 30s jitter 0.2
    env DEPLOY_ENV production
    env NOTIFY_URL {env.SLACK_WEBHOOK_URL}
  }
}

Configure Provider-Compatible HMAC

1. Use provider github, provider gitea, provider stripe, or provider cituro for webhook providers with their own signature format.
2. Provider mode disables timestamp/nonce replay protection (providers do not send those headers).
3. signature_header, timestamp_header, nonce_header, and tolerance are forbidden in provider mode (compile error).

hcl

/webhooks/github {
  auth hmac {
    provider github
    secret env:GITHUB_WEBHOOK_SECRET
  }
  pull { path /pull/github }
}

/webhooks/gitea {
  auth hmac {
    provider gitea
    secret env:GITEA_WEBHOOK_SECRET
  }
  pull { path /pull/gitea }
}

/webhooks/stripe {
  auth hmac {
    provider stripe
    secret env:STRIPE_SIGNING_SECRET
  }
  pull { path /pull/stripe }
}

/webhooks/cituro {
  auth hmac {
    provider cituro
    secret env:CITURO_WEBHOOK_SECRET
  }
  pull { path /pull/cituro }
}

Use SSE Streaming (v2.5.3+)

1. SSE replaces polling for real-time webhook delivery — use GET {pull.path}/stream instead of repeated POST .../dequeue.
2. ACK/NACK operations use the same existing POST endpoints; no protocol change.
3. Multiple concurrent SSE connections act as competing consumers.
4. Configure keepalive interval (keepalive) and max connection duration (max_duration) in the route's pull block.

bash

# Connect SSE stream (persistent, server pushes events)
curl -sS -N "http://localhost:9443/pull/github/stream" \
  -H "Authorization: Bearer $HOOKAIDO_PULL_TOKEN"

# ACK received event
curl -sS -X POST "http://localhost:9443/pull/github/ack" \
  -H "Authorization: Bearer $HOOKAIDO_PULL_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"lease_id":"lease_xyz"}'

Configure Queue Backends

1. Default to sqlite unless the task explicitly needs ephemeral dev mode or shared Postgres storage.
2. Treat memory and postgres as additive v2 modules, not replacements for existing sqlite workflows.
3. When using postgres, document the DSN source and validate health plus backlog endpoints after startup.

Prefer these patterns:

hcl

queue sqlite

queue memory

queue postgres

Operate Queue and DLQ

1. Start with health details and backlog endpoints.
2. Inspect DLQ before requeue or delete.
3. If requeueing many items, explain expected impact and rollback path.
4. Require clear operator reason strings for mutating admin calls.

Use:

• GET /healthz?details=1
• GET /backlog/trends
• GET /dlq
• POST /dlq/requeue
• POST /dlq/delete

Use MCP Mode for AI Operations

1. Default to --role read for diagnostics.
2. Enable mutations only with explicit operator intent:
   • --enable-mutations --role operate --principal <identity>
3. Enable runtime control only for admin workflows:
   • --enable-runtime-control --role admin --pid-file <path>
4. Include reason for mutation calls and keep it specific.

Register as Claude Code MCP Plugin

Add to .claude/settings.json (or ~/.claude/settings.json for global use):

json

{
  "mcpServers": {
    "hookaido": {
      "command": "hookaido",
      "args": [
        "mcp", "serve",
        "--config", "./Hookaidofile",
        "--db", "./.data/hookaido.db",
        "--role", "read"
      ]
    }
  }
}

For operate role (queue mutations):

json

{
  "mcpServers": {
    "hookaido": {
      "command": "hookaido",
      "args": [
        "mcp", "serve",
        "--config", "./Hookaidofile",
        "--db", "./.data/hookaido.db",
        "--enable-mutations",
        "--role", "operate",
        "--principal", "claude"
      ]
    }
  }
}

The MCP server exposes structured tools directly — no shell output parsing. Claude Code discovers available tools at startup and uses them with typed parameters.

Verify Public Releases

1. Prefer official release assets from the public Hookaido repo.
2. When supply-chain assurance matters, validate checksums, signature material, and provenance before rollout.
3. Keep verification optional by default so existing skill flows do not become heavier unless the task requires it.

Use:

• hookaido verify-release --checksums ./hookaido_v2.6.0_checksums.txt --require-provenance

Validation Checklist

• hookaido config validate returns success before runtime start/reload.
• hookaido config validate --strict-secrets is used when secret refs, Vault, or public-release rollout validation matters.
• Health endpoint is reachable and reports expected queue/backend state.
• Pull consumer can dequeue, ack, nack, and extend with valid token (HTTP, SSE, and optional gRPC transport), including batch ack/nack when enabled.
• For push mode, retry/timeout behavior is explicitly configured.
• For exec mode, handler script is executable, reads stdin, and uses exit codes correctly (0=ack, non-zero=retry, 126/127=DLQ).
• For queue postgres, runtime is started with --postgres-dsn or HOOKAIDO_POSTGRES_DSN.
• Any DLQ mutation is scoped, justified, and logged.

Safety Rules

• Do not disable auth to "make tests pass."
• Do not suggest direct mutations before read-only diagnostics.
• Treat queue operations as at-least-once; require idempotent handlers.
• Keep secrets in env: or file: refs.
