    ## Introduction


    The **CAPEX API** enables you to integrate your application with the CAPEX system. The CAPEX API is REST-based and follows JSON:API principles for structuring responses.


    Starting from version 1.0, the API is stable. We are continuously improving our API, and new endpoints will be added. Any updates or changes within this major version will be backward-compatible and can be found in this documentation.


    For getting access to the CAPEX API, please reach out to us at: `kontakt@alasco.de`.


    The base URL for all endpoints is:

    `https://api.alasco.de/capex/v1`


    The CAPEX API supports compressed payloads. If you would like to make use of this, you have to specify the `Accept-Encoding` header. Supported encodings are `gzip` and `br`.


    ### Domain model


    Objects relate as follows (each `→` is a navigable sub-resource):


    - **Assets** and **Measures** are the CapEx-specific top-level objects; a **Measure** → **Contracts**, and invoices are submitted against an **Asset**.

    - **Contractor** and **Contracting Entity** → **Contracts**.

    - **Contract** → **Change Orders**, **Invoices**, contract terms, **Documents** and **Custom Fields**.

    - **Invoice** → **Documents** and **Tags** (Change Orders also carry **Documents**).


    ### CAPEX API Overview


    The CAPEX API provides endpoints to:

    - Retrieve and manage invoices, invoice tags, and invoice documents

    - Retrieve assets, contracts, contractors, and measures


    The CAPEX API uses pagination. The page size is 100, and additional pages can be accessed using a `next` link.

          List endpoint responses are paginated in the Alasco API. By calling the endpoint without the

          pagination parameter you will receive the first page. If not all elements fit on one page there will

          be a `next` link provided in the response''s `links` object. By calling this link you will receive

          the next page.

          You can filter on certain attributes by specifying them as a GET parameter along

          with an operation, e.g. `filter[name.exact]=abc`.


          Currently supported operations are:

          * `exact`: Expects one value

          * `contains`: Expects one value

          * `less_than_equal`: Expects one value

          * `greater_than_equal`: Expects one value

          * `range`: Expects two values

          * `in`: Expects one or multiple values

          * `not_in`: Expects one or multiple values


          The following attributes support filtering:


          | **Attribute** | `exact` | `contains` | `less_than_equal` | `greater_than_equal` | `range` | `in` | `not_in` |

          | :--- | :---: | :---: | :---: | :---: | :---: | :---: | :---: |

          | `id` |   |   |   |   |   | x | x |

          | `description` | x | x |   |   |   |   |   |

      description: '

        The Alasco API uses a combination of API keys and API tokens to authenticate requests. The API key

        needs to be sent in a header field called `X-API-KEY`.

        '
      in: header
      name: X-API-KEY
      type: apiKey
    API Token:
      description: '

        In addition to an API key, one has to specify an API token. There can be one or more tokens in use

        for the same API key. The token needs to be sent in a header field called `X-API-TOKEN`.

        Right now, it''s not possible to create API keys and API tokens from within Alasco.

        If you are interested in using the Alasco API, please reach out to the

        [support team](mailto:support@alasco.de). They will assist you in generating a key and token pair.
