    ## 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.
