# Use CallForMe in n8n, Zapier, and Make

> Use the REST API at https://callforme.tel/v1 with an Authorization: Bearer cfm_ header, using a key from your account page. POST /calls to start a call, then GET /calls/{id}?wait=30 until status is ended, and map the answers onward. n8n's AI Agent can also use the MCP URL through its MCP Client Tool.

Automations don't have a person in the loop to open a setup link, so set up your account first. Connect CallForMe in any chat agent and place one call (that's where you add $10), then create a `cfm_` key on the [account page](https://callforme.tel/account) and store it as a credential in your tool. Check your balance with `GET /account`.

## n8n

**With an AI Agent:** add an **MCP Client Tool** sub-node to your AI Agent node. Endpoint: `https://callforme.tel/mcp`, transport **HTTP Streamable**, authentication **Bearer Auth** with your `cfm_` key. The node also offers **OAuth2** with dynamic client registration, which signs you in with one click like any other agent; use the key when the workflow runs unattended.

**Without an agent:** use two HTTP Request nodes.

1. **POST** `https://callforme.tel/v1/calls`, header `Authorization: Bearer cfm_your_key`, JSON body:

```json
{
  "phone": "+12145550123",
  "business_name": "Lakeside Print & Copy",
  "goal": "Ask if order #4411 is ready for pickup and their closing time today",
  "questions": ["Is order #4411 ready?", "What time do you close today?"],
  "on_behalf_of": "Jordan Park"
}
```

2. **GET** `https://callforme.tel/v1/calls/{{$json.call_id}}?wait=30` in a loop until `status` is `ended`. Read `answers` and `outcome`.

## Zapier

1. Action: **Webhooks by Zapier**, **Custom Request**, method POST, URL `https://callforme.tel/v1/calls`, headers `Authorization: Bearer cfm_your_key` and `Content-Type: application/json`, with the JSON body above.
2. Add **Delay by Zapier** (for example 5 minutes).
3. Another **Custom Request**: GET `https://callforme.tel/v1/calls/<call_id>?wait=30`.
4. Use **Paths** or **Filter** on `status` and pass `answers` to Sheets, Slack, or email.

## Make

1. **HTTP** module, **Make a request**: POST `https://callforme.tel/v1/calls`, header `Authorization: Bearer cfm_your_key`, body type raw JSON.
2. **Sleep** a few minutes, or use a **Repeater** with a GET to `/v1/calls/{call_id}?wait=30` and stop when `status` is `ended`.
3. Map `answers` and `outcome.summary` into the next module.

## Questions during the call

A workflow can't think on its feet, so give the call everything it needs up front in `details`, and set `constraints` for anything it must not agree to. If the business still asks something, `pending_question` appears in the GET response. You can answer with `POST /v1/calls/{id}/answer` and `{"answer": "..."}`, or let it pass: after about 50 seconds the voice assistant says it will call back.

Full endpoint list in the [REST API docs](/docs/rest-api).

## Try it

Paste this into n8n, Zapier, and Make:

> Every weekday at 10am, call the pharmacy from the sheet and ask if my prescription is ready; post the answer to Slack.

## FAQ

### Can a workflow use a setup link?

Not well, since nobody is there to open it. Create a key on the account page at callforme.tel/account first and store it as a credential.

### How long should I wait before checking?

A quick question call usually ends within a few minutes. Hold waits can run up to the 30 minute limit. GET with ?wait=30 returns early as soon as something changes.

### Is there a webhook when the call ends?

Not today. Poll GET /v1/calls/{id} with the wait parameter.

### Can I bulk-call a list?

You can loop over a list of businesses, but calls must be to businesses and follow the terms: no telemarketing or sales calls, and at most 3 calls per number per day.
