Additional Fields

When tracking a page through several delivery services, you must provide additional information, such as the post code or recipient's surname. The list of all required and optional additional fields is sent in the extra_fields array of the Courier object. The values of the additional fields can be either random or selected only from the available options. Both options are described in this section.

1. Additional fields with random value

Object example:

        
{
    "name": "zip",
    "type": "text",
    "placeholder": "Recipient post code",
    "field_regexp": "^(3S|KG)([A-Z]{4}|)\\d{9}$",
    "validate_regexp": "^[A-Z0-9]{5,8}$"
}
        
    

Object description:

field_regexp	String	A regular expression used to check if this field is required to get information from the delivery service. If the tracking number matches this regular expression, the field is required.
