## Run it

**TypeScript**

```ts
import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const deployed = await pd.triggers.deploy({
  id: "postmark-new-email-opened",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    postmark: { authProvisionId: "apn_xxxxxxx" },
    postFirstOpenOnly: true,
  },
  webhookUrl: "https://example.com/webhooks/postmark",
})

console.log(deployed.id)
```

**cURL**

```bash
curl -X POST https://api.pipedream.com/v1/connect/{project_id}/triggers/deploy \
  -H "Content-Type: application/json" \
  -H "X-PD-Environment: production" \
  -H "Authorization: Bearer {access_token}" \
  -d '{
    "external_user_id": "{external_user_id}",
    "id": "postmark-new-email-opened",
    "webhook_url": "https://example.com/webhooks/postmark",
    "configured_props": {
      "postmark": { "authProvisionId": "apn_xxxxxxx" },
      "postFirstOpenOnly": true
    }
  }'
```

**MCP**

MCP servers expose Postmark actions as on-demand tools.

New Email Opened is an event source, so your application deploys it with the Connect SDK or API and then either receives each event at a webhook URL or retrieves events on demand with the trigger events API.

## Event delivery

Every event is sent to the HTTP endpoint you choose when you deploy the source. Or: no webhook required — your app or agent can fetch recent events from the [trigger events API](https://pipedream.com/docs/connect/api-reference/list-trigger-events.md) instead.
