# openclaw-action workflow

This skill ships an importable workflow at:

- `assets/openclaw-action.workflow.json`

It implements a real local OpenClaw → n8n router.

## What it does

- accepts `POST /webhook/openclaw-action`
- normalizes incoming JSON into an action contract
- supports these actions in the shipped asset:
  - `append_log`
  - `get_logs`
  - `notify`
  - `send_notification_draft`
  - `send_email_draft`
  - `list_email_drafts`
  - `delete_email_draft`
  - `send_gmail_draft` (alias: `send_approved_email`)
  - `create_calendar_event`
  - `approval_queue_add`
  - `approval_queue_list`
  - `approval_queue_resolve`
  - `approval_history_attach_execution`
  - `fetch_and_normalize_url`
  - `inbound_event_filter`
- returns normalized JSON responses
- returns `400` for unknown actions
- returns `400` when required args are missing

## Current side effects

### `append_log`

- appends records into workflow static data under key:
  - `actionLog`
- keeps the most recent `200` entries
- persists in n8n's database when the workflow execution succeeds

Example stored record:

```json
{"ts":"2026-03-12T07:00:00Z","source":"openclaw-action","request_id":"abc","text":"backup complete"}
```

### `send_notification_draft`

- queues an approval-gated notification proposal into workflow static data under key:
  - `approvalQueue`
- when resolved with `decision=approve`, it executes the existing `notify` path and sends through Telegram + Discord
- uses only the already-configured notification credentials in the live n8n instance

### Gmail + Calendar approval-gated actions

Actions:
- `send_email_draft`
- `list_email_drafts`
- `delete_email_draft`
- `send_gmail_draft` (alias: `send_approved_email`)
- `create_calendar_event`

Behavior:
- queue proposals into workflow static data under key:
  - `approvalQueue`
- keep the most recent `200` pending entries
- return explicit approval policy metadata per action (`approval.policy`, `approval.required`, `approval.mutation_level`)
- do **not** execute Gmail/Calendar side effects directly in the shipped starter workflow
- are intended for host-side execution via the included `gog` bridge after explicit approval resolution

Approval policy defaults:
- `send_email_draft`, `delete_email_draft`, `send_gmail_draft` / `send_approved_email`, `create_calendar_event`
  - `approval.required = true`
  - `approval.mutation_level = "high"`
- `list_email_drafts`
  - `approval.required = true`
  - `approval.mutation_level = "low"` (read-only action, still routed through approval queue for explicit operator acknowledgement + audit trail)

### `approval_queue_resolve`

- removes one item from `approvalQueue`
- appends the resolved entry into:
  - `approvalHistory`
- supports optional notification on approval/rejection
- executes notification drafts inline when the approved item kind is `notification`

### `approval_history_attach_execution`

- patches an existing resolved history item in `approvalHistory`
- designed for host-side executors that run outside n8n itself
- used by the included `scripts/resolve-approval-with-gog.py` bridge to attach Gmail/Calendar execution results

### `fetch_and_normalize_url`

- fetches a remote `http` or `https` URL from inside n8n
- normalizes HTML/text/JSON into a single response shape
- returns title/excerpt/body text suitable for downstream summarization or logging
- uses n8n's runtime HTTP helper inside the Code node rather than relying on global `fetch`
- supports optional arg `skip_ssl_certificate_validation: true` for runtimes with incomplete CA trust

### `inbound_event_filter`

- classifies inbound events as `urgent`, `important`, `watch`, or `deduped`
- stores recent events in:
  - `inboundEvents`
- stores recent dedupe keys in:
  - `eventDedup`
- can fan out a notification for urgent/important non-duplicate events

### `notify`

- sends a Telegram message using credential:
  - `Telegram Bot (OpenClaw)`
- sends a Discord message using credential:
  - `Discord Bot Auth`
- current targets mirror the already-working reminder workflow

## Why workflow static data first

Why this first:
- built-in, no extra credentials
- persists without guessing writable filesystem paths
- good fit for queues, recent breadcrumbs, and small operational state
- lets us implement safe approval-gated patterns immediately

When to add provider-backed steps later:
- email draft creation in Gmail/Outlook
- calendar writes in Google Calendar
- Airtable/Sheets append pipelines
- long-retention logs or external archival

## 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

- test: `http://192.168.153.113:18808/webhook-test/openclaw-action`
- prod: `http://192.168.153.113:18808/webhook/openclaw-action`

## Host bridge notes

The included host bridge `scripts/resolve-approval-with-gog.py` is for the case where Gmail/Calendar auth exists on the OpenClaw host via `gog`, not inside n8n itself.

Behavior:
- resolves an approval item through `openclaw-action`
- executes supported kinds on the host:
  - `email_draft` → `gog gmail drafts create`
  - `email_list_drafts` → `gog gmail drafts list`
  - `email_draft_delete` → `gog gmail drafts delete`
  - `email_draft_send` → `gog gmail drafts send`
  - `calendar_event` → `gog calendar create`
- writes execution metadata back via `approval_history_attach_execution`

Important automation note:
- real unattended execution needs `GOG_KEYRING_PASSWORD` available to the executor
- the included bridge auto-loads `/home/openclaw/.openclaw/credentials/gog.env` when present
- keep that file mode `600` if you use it for `GOG_ACCOUNT` / `GOG_KEYRING_PASSWORD`
- without the password, non-TTY `gog` calls will fail when the file keyring tries to prompt
- `--dry-run` works without touching Google state and is useful for plumbing verification

## Validation

Run the local validator before import/package changes:

```bash
python3 scripts/validate-workflow.py assets/openclaw-action.workflow.json
