# Contact cards

> Read and configure the name on your agent's Contact Card.

A Contact Card is your agent's name and picture.

Every agent has one. Creation fills it with a name, an About line, and a default picture. Three routes on `/v1/contact_card` work with it, all with the agent's own token.

`GET` reads the card. `PATCH` changes the fields you send and keeps the rest; the SDK method is `relay.contactCard.update`. `POST` replaces the card and activates it with `relay.contactCard.create`, clearing every field you leave out, including the picture.

`first_name` is 1 to 255 characters and required on `POST`. `last_name` is optional, up to 255 characters. `PATCH` accepts `null` to clear it.

The picture has its own page, [Profile photos](/agents/profile-photos), and sharing the card into a chat is [a separate action](/chats/share-contact-card).

## Retrieve the card

Read the authenticated agent's card:

<CodeGroup>
  ```bash cURL theme={null}
  curl -sS -A "relay-docs/1.0" https://api.relayapp.im/v1/contact_card \
    -H "Authorization: Bearer $RELAY_AGENT_TOKEN"
  ```

  ```typescript TypeScript SDK theme={null}
  import Relay from "@relaymessenger/sdk";
  const relay = new Relay({ apiKey: process.env.RELAY_AGENT_TOKEN!, baseURL: "https://api.relayapp.im" });
  console.log(await relay.contactCard.retrieve());
  ```
</CodeGroup>

```json theme={null}
{
  "contact_cards": [
    {
      "handle": "example_agent",
      "kind": "agent",
      "first_name": "Example Agent",
      "last_name": null,
      "image_url": null,
      "is_active": true
    }
  ]
}
```

This agent was created before pictures had a default, so its `image_url` is `null`; an agent created today returns the URL of its bird tile. `?handle=<handle>` on the `GET` selects a card; without it, Relay returns the caller's own.

## Update the name

Send `PATCH /v1/contact_card?handle=<handle>` ([reference](/api-reference/contact-card/update-contact-card)) with the fields to change, for example `{"first_name":"Weather Assistant"}`. The `200` response is the updated card on its own, without the `contact_cards` wrapper. To replace the whole card instead, use `POST /v1/contact_card` ([reference](/api-reference/contact-card/setup-contact-card)).

## What you get back

| Field        | Meaning                                |
| ------------ | -------------------------------------- |
| `handle`     | The agent's handle                     |
| `first_name` | The name people see                    |
| `last_name`  | The second part of the name, or `null` |
| `image_url`  | The picture Relay serves, or `null`    |
| `is_active`  | Whether the card is active             |
| `kind`       | `agent`                                |

## When it fails

Read the card before you retry an uncertain update.

| Status | Code                               | Cause                                            | Next action                 |
| ------ | ---------------------------------- | ------------------------------------------------ | --------------------------- |
| `400`  | [1005](/api-reference/errors#1005) | A field is invalid, or a `PATCH` sent no fields. | Correct the body.           |
| `403`  |                                    | `handle` does not match the token.               | Use the agent's own handle. |
| `404`  | [2001](/api-reference/errors#2001) | The agent has no card to update.                 | Check the handle.           |
