This section describes all available operations of the NAVAX Recurring Contracts Interface web service. Each operation is called via the CallWebservice endpoint by passing the operation name in the Operation parameter and the required fields as a JSON object in the Payload parameter. The required fields of each operation can also be queried at runtime via the ReadMe endpoint.

CreateContract

Creates a new contract header in Business Central. Required fields: Example payload:

    "Description": "Maintenance Contract 2026",
    "Starting Date": "2026-01-01",

CreateContractLine - Bundles

To create bundles, the CreateContractLine operation can be used. First, the bundle header must be created by setting the Bundle Type field to Bundle and the Type field to a space ( ).
