How to Use OpenClaw Webhooks

OpenClaw webhooks are not the same thing as internal hooks. The internal hooks system reacts to events inside the gateway. The Webhooks plugin exposes authenticated HTTP routes so external systems can create and control TaskFlows. That distinction matters because you are deciding whether automation begins inside OpenClaw or whether another system should be able to push work in from the outside.

When this is the right move

Use the Webhooks plugin when you want Zapier, n8n, a CI pipeline, or an internal service to trigger managed OpenClaw work without writing a full custom plugin first. It is a particularly good fit when a trusted system already knows the event boundary and you want OpenClaw to handle the downstream orchestration and child tasks.

The practical workflow

1. Enable the webhooks plugin on the gateway host and define one route at a time with an explicit path, sessionKey, and secret.
2. Store the route secret in an environment variable, file, or other secret reference instead of leaving it inline when you can avoid that.
3. Restart the gateway so the route is loaded, then send a small authenticated POST that creates or queries a flow.
4. Keep the route bound to the narrowest useful sessionKey because the route acts with that TaskFlow authority.
5. Once the route works, layer on external automation, retries, or child tasks. Do not make the first test an entire production pipeline.

Grounded command or config pattern

The plugin docs show route config under plugins.entries.webhooks.config. A minimal route looks like this.

{
  plugins: {
    entries: {
      webhooks: {
        enabled: true,
        config: {
          routes: {
            zapier: {
              path: "/plugins/webhooks/zapier",
              sessionKey: "agent:main:main",
              secret: {
                source: "env",
                provider: "default",
                id: "OPENCLAW_WEBHOOK_SECRET",
              },
              controllerId: "webhooks/zapier",
              description: "Zapier TaskFlow bridge",
            },
          },
        },
      },
    },
  },
}

Requests are JSON POSTs with either a Bearer secret or the dedicated secret header. The documented actions include create_flow, list_flows, resume_flow, finish_flow, cancel_flow, and run_task. If a secret-backed route cannot resolve its secret at startup, the plugin skips that route instead of exposing a broken endpoint.

Operator notes

This plugin is deliberately narrow: each route is trusted to act with the TaskFlow authority of its configured session. The plugin adds shared-secret auth, body-size and timeout guards, fixed-window rate limiting, and in-flight request limiting before the request reaches TaskFlow APIs. That is a good reminder that webhook convenience should still feel like an operator tool, not an anonymous public API.

Rollout approach

For OpenClaw webhooks, start with one route and one harmless action like create_flow or list_flows. Proving the auth and session binding are correct is much more important than wiring every downstream automation on the first pass. A tiny, well-understood route is easier to trust than a giant generic one.

Common mistake

The common mistake is treating the command or config key as the whole feature. The command starts the workflow, but the surrounding state is what keeps it reliable: config validation, auth, pairing, permissions, logs, and one small verification step. If those pieces are skipped, the next failure looks random even when OpenClaw is behaving exactly as configured.

Maintenance rhythm

Once this is working, write down the exact command, config path, or approval decision you used. Future you will not remember the tiny detail that made the setup safe. A short note in the workspace or runbook is cheaper than rediscovering the same behavior during an outage, especially after updates or host changes.

Safety checks

Use a unique strong secret per route, bind the route to the narrowest sessionKey that fits the workflow, and expose only the specific path you need. Remember that the route can inspect and mutate flows owned by that session. If you make the route too broad, you are widening the blast radius of any leaked secret or misbehaving automation system.

How to verify it worked

Send one authenticated test request and confirm the response is {"ok": true, ...} rather than a generic transport success hiding a route failure. Then inspect the resulting TaskFlow state through your normal operator path. If the webhook works but the flow behavior is wrong, debug the session binding and requested action before you blame the transport.

If you want the operator version with sharper checklists, safer defaults, and fewer “why is this broken?” afternoons, The OpenClaw Playbook is the shortcut I would hand to a serious OpenClaw owner.
