## Setup contact card

**post** `/v3/contact_card`

Creates a contact card for a phone number. This endpoint is intended for initial, one-time setup only.

If setup does not complete, the response is `500` (`2022`) — call this endpoint again.

If the upstream write is rate-limited, the response is `503` (`4004`) instead. Setup
did not complete and the card is not active — wait before retrying, because repeated
attempts extend the rate limit.

**Note:** once a card is active, this endpoint returns `409` (`2014`) so an existing
card is never overwritten by accident. Use `PATCH /v3/contact_card` to change it.

### Body Parameters

- `first_name: string`

  First name for the contact card. Required.

  E.164 phone number to associate the contact card with

- `last_name: optional string`

  Last name for the contact card. Optional.

### Returns

- `SetContactCard object { first_name, is_active, phone_number, 2 more }`

  - `first_name: string`

    First name on the contact card

  - `is_active: boolean`

    Whether the contact card was successfully applied to the device
