# Update a customer

PATCH https://www.your-store.co.il/api/v1/customers/{id}
Content-Type: application/json

Details, or `active` to approve / lock. Requires `customers:write`.

Reference: https://docs.coi.co.il/customers/update-customer

## Authentication

- `Authorization` header (bearer token, required) — An API key from the store's admin: חנות > API ומפתחות. Send it as `Authorization: Bearer coi_sk_...` (or `X-Api-Key: coi_sk_...`). Never in the URL - `?apikey=` is refused with 400.

## Request

### Path parameters

- `id` (integer, required)

### Body (application/json)

This endpoint expects a CustomerInput.

- `email` (string, optional) — Required on create. Unique in the store (409 `email_taken`).
- `firstName` (string, optional)
- `lastName` (string, optional)
- `phone` (string, optional)
- `newsletter` (boolean, optional)
- `notes` (string, optional, nullable)
- `active` (boolean, optional) — Update only. true approves a pending customer (it is emailed that it can log in) or unlocks one; false locks it out at once.

## Response

### 200

The updated customer.

- `ok` (true, optional)
- `data` (Customer, optional)

## Errors

### 400 Bad Request Error

The request is not valid - a field of the wrong type, a missing field, a bad parameter.

- `ok` (false, optional)
- `error` (ErrorError, optional)

### 401 Unauthorized Error

Missing, invalid, revoked or expired API key. The same answer for all of them.

- `ok` (false, optional)
- `error` (ErrorError, optional)

### 403 Forbidden Error

The key lacks the permission (`insufficient_scope`), or the site's plan does not include the API (`plan_required`).

- `ok` (false, optional)
- `error` (ErrorError, optional)

### 404 Not Found Error

No such row in this store (ids of another store are never found).

- `ok` (false, optional)
- `error` (ErrorError, optional)

### 429 Too Many Requests Error

More than 120 requests a minute with one key. Wait `Retry-After` seconds.

- `ok` (false, optional)
- `error` (ErrorError, optional)

## Types

### Customer

- `id` (integer, optional)
- `email` (string, optional)
- `firstName` (string, optional)
- `lastName` (string, optional)
- `phone` (string, optional, nullable)
- `newsletter` (boolean, optional)
- `status` (enum, optional) — `pending` = waiting for the owner's approval ("אשר לקוחות ידנית" is on and it never logged in).
  - Allowed values: `active`, `pending`, `locked`
- `notes` (string, optional, nullable)
- `registeredAt` (string, optional, nullable)
- `lastVisitAt` (string, optional, nullable)

### ErrorError

- `code` (string, optional) — Stable, machine-readable: `unauthorized`, `insufficient_scope`, `plan_required`, `invalid_field`, `invalid_parameter`, `invalid_json`, `json_required`, `not_found`, `method_not_allowed`, `nothing_to_update`, `plan_limit`, `email_taken`, `registration_disabled`, `rate_limited`, `too_many_failures`, `https_required`, `key_in_url`, `server_error`.
- `message` (string, optional) — What went wrong, in English, for a person.
