# Attach their identity

`PUT /api/v1/customer/contact`

## Request

- Base URL: `https://hproxy.com`
- URL: `https://hproxy.com/api/v1/customer/contact`
- Auth: API key in header `X-API-Key`

Set the customer's email and your display name for them, ideally right after your own signup flow, so your customer book, your business dashboard and our support all see a person instead of an opaque id. Each field: **omitted = unchanged, empty string = cleared, value = set**. We never send mail to this address; it is identity, not a channel.

## Request body

- object
  - `email` string: The customer's email address. Stored lowercased. Empty string clears it.
  - `label` string: Your display name for them, 1 to 120 characters. Empty string clears it.

## Response `200`

Success

- object

## Other responses

- `400`: Invalid input. The body names the field and the accepted set.
- `401`: Missing or invalid API key.
- `429`: Rate limited. Retry after the delay in the response.
