## OpenAPI

````yaml PUT /receipts/{id}
openapi: 3.1.0
info:
  title: Contazen API
  version: 1.2.0
  description: >
    Build powerful integrations with the Contazen invoicing platform. The
    Contazen API is organized around REST, 

    has predictable resource-oriented URLs, accepts JSON request bodies, returns
    JSON-encoded responses, 

    and uses standard HTTP response codes, authentication, and verbs.


    ## Authentication

    The API uses Bearer token authentication. Include your API key in the
    Authorization header.


    ### Getting your API Key

    1. Log in to your Contazen account

    2. Navigate to Settings > API

    3. Generate or copy your API key (starts with `sk_live_` for production or
    `sk_test_` for testing)


    ### Using the API Key

    Include your API key in the Authorization header:

    ```

    Authorization: Bearer sk_live_YOUR_API_KEY

    ```


    ### Example Request with cURL

    ```bash

    curl --request GET \
      --url https://api.contazen.ro/v1/clients \
      --header 'Authorization: Bearer sk_live_YOUR_API_KEY' \
      --header 'Accept: application/json'
    ```


    ## Rate Limiting

    - 1000 requests per hour per API key

    - 100 create operations per minute per API key


    Rate limit information is included in response headers:

    - `X-RateLimit-Limit`: Maximum requests allowed

    - `X-RateLimit-Remaining`: Requests remaining

    - `X-RateLimit-Reset`: Reset time (Unix timestamp)


    ## Pagination

    All list endpoints return paginated results with the following format:

    ```json

    {
      "success": true,
      "data": {
        "object": "list",
        "data": [...],
        "has_more": true,
        "total": 245,
        "page": 1,
        "per_page": 50,
        "total_pages": 5
      },
      "meta": {
        "version": "v1",
        "request_id": "req_1a2b3c4d",
        "response_time": "23.45ms"
      }
    }

    ```


    ## Multi-Work-Point Access

    API keys belong to a specific work point but can access data from all work
    points

    within the same parent company.


    ## Error Handling

    The API uses conventional HTTP response codes to indicate success or
    failure. 

    In general: 2xx codes indicate success, 4xx codes indicate an error due to
    the 

    information provided, and 5xx codes indicate an error with Contazen's
    servers.


    ## Expanding Nested Objects

    Many endpoints support the `expand` parameter to include related objects in
    the response.

    This follows the Stripe API pattern. For example:

    - `expand[]=lines` - Include invoice line items

    - `expand[]=payments` - Include payment records

    - `expand[]=client` - Include full client object


    ## Localization

    The API supports multiple languages through:

    - `locale` query parameter (en, ro)

    - `Accept-Language` header
