Handling Http GET requets
The method will be able to get all values from the query string.
A request is made to API Endpoint using the following URL:
Say we want to create a field named UserId that will hold the value that is passed via query string in the filter parameter. To achieve this, create a field, name it UserId and in the Reference field type the name of the query string parameter. In our example, this is filter. Now, whenever you use the token associated with this field (i.e. [UserID]), we get the value that was passed in the query string (i.e. 123).
If the reference option is left empty DnnApiEndpoint uses the name as a reference.
