There are two methods to register a user or create an Ident - either over the API or over the web-form.
The API is the most flexible method to register a user and receive their Ident-ID. It allows you to collate information required for the identification from multiple sources and automate the process.
The web-form allows manual entry of user information to create an Ident. This is option is suitable for low volumes or as a back-up, but can also be disabled upon request.
