Attention!: We recommend only using Local UniFi accounts due to short token lengths provided by UniFi Cloud Accounts. Also, UniFi Cloud Accounts using 2FA won't work!

Note: When creating a Local UniFi account ensure you give 'Full Management' access rights to the Network controller. The 'Hotspot Role' won't give access to the API and therefore the application will throw errors.

Services

The project consists of two main services: Web and API.

Web Service

The Web service is a user interface accessible through a web browser. It provides functionality for generating, viewing, and managing vouchers within the UniFi system.

API Service

The API service allows programmatic access to voucher-related functionalities. It is designed for developers who wish to integrate voucher management into their applications or automate voucher generation processes. Below are the details of the different endpoints available in the API:

    "endpoints": [
      "/api",
      "/api/types",
      "/api/voucher/:type",
      "/api/vouchers"
    ]
  }
}

2. /api/types
