# openclaw-action workflow
This skill ships an importable draft workflow at:
- `assets/openclaw-action.workflow.json`
It implements the first safe router contract for local OpenClaw → n8n calls.
## What it does
- accepts `POST /webhook/openclaw-action`
- normalizes incoming JSON into:
- `action`
- `args`
- `request_id`
- routes two known actions:
- `append_log`
- `notify`
- returns normalized JSON responses
- returns `400` for unknown actions
- returns `400` when required branch args are missing
## Intentional security choice
The exported workflow leaves the Webhook node auth unset in the JSON file.
Why:
- n8n credentials are instance-local
- secrets should not be embedded in a shareable skill asset
After import, set this manually in n8n:
- Webhook node → **Authentication**`Header Auth`
- bind a credential with:
- header name: `x-openclaw-secret`
- header value: your generated shared secret
## Import steps
1. In n8n, create or open a workflow.
2. Import `assets/openclaw-action.workflow.json`.
3. Open the **Webhook** node.
4. Set **Authentication** to `Header Auth`.
5. Bind your local credential.
6. Save.
7. Use **Listen for test event** and call the test URL first.
8. Once successful, activate the workflow for production URL use.
## Expected URLs
Assuming the current local service address:
- test: `http://192.168.153.113:18808/webhook-test/openclaw-action`
- prod: `http://192.168.153.113:18808/webhook/openclaw-action`
## Test payloads included
- `assets/test-append-log.json`
- `assets/test-notify.json`
## Example tests
Direct curl:
```bash
curl -i -X POST 'http://192.168.153.113:18808/webhook-test/openclaw-action' \
-H 'Content-Type: application/json' \
-H 'x-openclaw-secret: YOUR_SECRET_HERE' \
--data @assets/test-append-log.json
```
Via skill helper:
```bash
export N8N_WEBHOOK_SECRET='YOUR_SECRET_HERE'
scripts/call-action.sh append_log --args '{"text":"backup complete"}' --test --pretty
```
## Expected success examples
### append_log
```json
{
"ok": true,
"request_id": "test-append-log-001",
"result": {
"action": "append_log",
"status": "accepted",
"preview": {
"text": "backup complete"
}
}
}
```
### notify
```json
{
"ok": true,
"request_id": "test-notify-001",
"result": {
"action": "notify",
"status": "accepted",
"preview": {
"title": "Workflow finished",
"message": "n8n router test"
}
}
}
```
## Expected failure examples
### unknown action
```json
{
"ok": false,
"request_id": "",
"error": {
"code": "unknown_action",
"message": "action is not supported"
}
}
```
### missing required args
```json
{
"ok": false,
"request_id": "",
"error": {
"code": "invalid_request",
"message": "required args are missing"
}
}
```
## Validation
Run the local validator before import/package changes:
```bash
python3 scripts/validate-workflow.py assets/openclaw-action.workflow.json
```
