AI Ability since v2.0.0

# get\_trigger\_schema

Get captured payload + mapping for a trigger — Return the last captured example payload, field mapping and conditions for a webhook+trigger so the agent can map against the real payload shape.

Return the last captured example payload, field mapping and conditions for a webhook+trigger so the agent can map against the real payload shape. Registered as the WordPress Ability `flowsystems-webhook-actions/get_trigger_schema`, so external AI tools (Claude Code, Cursor) can call it over MCP or REST with a scoped API token.

/ Plan step shape

```
{ "ability": "get_trigger_schema", "input": { "webhook_id": …, "trigger": … } }
```

/ Scope & confirmation

Minimum API-token scope for external (MCP/REST) callers: `read`. Read-only — the agent runs it freely while planning and verifying.

/ Input fields

| Name | In | Type | Req | Description |
| --- | --- | --- | --- | --- |
| webhook\_id | param | integer | yes |  |
| trigger | param | string | yes |  |

/ Examples

Plan step as the AI Builder proposes it

  "summary": "…",
  "input": {
    "webhook_id": 12,
    "trigger": "wpcf7_mail_sent"
  }
}
```
