# Update a Client

Update an existing client account.

Endpoint: POST /v1/clients/{clientId}
Version: 1.0.0-beta.27
Security: ApiKeyAuth

## Security:

  - `ApiKeyAuth` (unknown)
    apiKey in header Api-Key

## Path parameters:

  - `clientId` (string, required)

## Header parameters:

  - `Client-Id` (string, required)

  - `X-Acting-As-Client-Id` (string)
    The child client this request acts on behalf of. A reseller still authenticates as itself — `Api-Key` and `Client-Id` stay the reseller's — and names the child here.

This works only from a parent to its own children. Merchants have no children, so a merchant calling as itself omits the header. Sending your own client ULID here is not the same as omitting it, and is rejected on some operations.

## Request fields (application/json):

  - `dba` (string | null)
    Updated Doing Business As (DBA) name for the client.

  - `type` (string)
    The type of client account.
    Enum: "reseller", "merchant"

  - `admin_contact_details` (object)
    Contact information supplied when updating a client. Every property is optional; send only the ones you are changing. Omitting a property leaves it as it was.

  - `admin_contact_details.first_name` (string)
    First name of the admin contact.

  - `admin_contact_details.last_name` (string)
    Last name of the admin contact.

  - `admin_contact_details.email` (string)
    Email address of the admin contact. Used as the login username.

  - `admin_contact_details.phone` (any)
    Phone number. The phone number must contain between 10 and 12 digits and can contain spaces, a leading `+` symbol (when used with a country  code), and the special characters `(`, `)`, `-`, and `.`. Alphabetical  characters are not allowed.

  - `admin_contact_details.time_zone` (string)
    The time zone of the account.
    Enum: "America/Los_Angeles", "America/Phoenix", "America/Denver", "America/Chicago", "America/New_York", "Pacific/Honolulu", "America/Anchorage"

  - `metadata` (object | null)
    Key-value pairs for storing additional information on the transaction. Send `null` to clear all metadata.
At most 50 keys. Keys may contain letters, digits, hyphens, and underscores, up to 40 characters. Values are strings up to 500 characters. Every limit below is enforced; a request that exceeds any of them is rejected.

## Response 200:

  - `200` (unknown)
    Client updated successfully

## Response 200 fields (application/json):

  - `id` (string, required)
    Unique identifier for the client.

  - `parent_id` (string, required)
    Unique identifier of the parent client account.

  - `dba` (string, required)
    Updated Doing Business As (DBA) name of the client.

  - `type` (string, required)
    The type of client account.
    Enum: "reseller", "merchant"

  - `admin_contact_details` (object, required)
    Contact information for the primary admin user of a client account, as returned on a response. The four required properties are always present and may be null, because a client created through an internal path is not held to the rules `ClientAdminContactDetailsInput` applies. A request uses `ClientAdminContactDetailsInput` to create and `ClientAdminContactDetailsUpdate` to amend.

  - `admin_contact_details.first_name` (string | null, required)
    First name of the admin contact.

  - `admin_contact_details.last_name` (string | null, required)
    Last name of the admin contact.

  - `admin_contact_details.email` (string | null, required)
    Email address of the admin contact. Used as the login username.

  - `admin_contact_details.phone` (any)
    Phone number. The phone number must contain between 10 and 12 digits and can contain spaces, a leading `+` symbol (when used with a country  code), and the special characters `(`, `)`, `-`, and `.`. Alphabetical  characters are not allowed.

  - `admin_contact_details.time_zone` (string, required)
    The time zone of the account.
    Enum: "America/Los_Angeles", "America/Phoenix", "America/Denver", "America/Chicago", "America/New_York", "Pacific/Honolulu", "America/Anchorage"

  - `metadata` (object | null)
