# Retrieve a client

GET https://api.modulards.com/api/public/v1/clients/{client_id}

Returns one client by id: its name, last name and company. Use it to check a client before you assign websites to it. A contact id answers 404.

Reference: https://api.docs.modulards.com/modular-ds-public-api/clients/manage-clients/retrieve-a-client

## Authentication

- `Authorization` header (bearer token, required) — Personal access token created in the Modular DS dashboard; read-only tokens can only call GET endpoints.

## Request

### Path parameters

### Query parameters
