# Authentication

> Authenticate every request with your SmartSend Organization ID.

The SmartSend Make.com API authenticates each request with a single header:

```
x-organization-id: <YOUR_ORGANIZATION_ID>
```

There are no separate API keys or tokens. Your **Organization ID** identifies your
workspace and authorizes the request.

<Warning>
  Treat your Organization ID as a secret. Anyone who has it can send messages and
  modify conversations in your workspace.
</Warning>

## Find your Organization ID

Your Organization ID is the workspace identifier shown in the SmartSend app URL
when a workspace is active:

```
https://app.smartsend.co.il/app/<organization-slug>/...
```

If you're not sure which ID to use, open the SmartSend dashboard, go to your
workspace settings, or contact [support@smartsend.com](mailto:support@smartsend.com).

## Verify it works

Call the `validate` endpoint to confirm your Organization ID is correct and that
WhatsApp is connected:

<CodeGroup>
  ```bash cURL theme={null}
  curl https://smartsend-server.otherwise.co.il/integrations/make/validate \
    -H "x-organization-id: YOUR_ORGANIZATION_ID"
  ```

  ```json 200 OK theme={null}
  {
    "success": true,
    "data": {
      "organizationId": "org_123",
      "organizationName": "Acme Inc.",
      "whatsappConnected": true
    }
  }
  ```
</CodeGroup>

If you get `Organization not found`, double‑check the ID. If `whatsappConnected`
is `false`, connect WhatsApp in the dashboard before sending messages.

## Using it in Make.com

When you set up a SmartSend module (or a generic **HTTP** module) in Make.com, add
a header named `x-organization-id` with your Organization ID as the value. Every
call in your scenario reuses it.
