URL parameters are bits of information appended to the end of a URL to pass data to the page. In our instance, the parameters will be used by the page to preselect form field options.
Given a standard URL (e.g.: https://demo.givebutter.com/form), parameters are added to a URL by appending a ‘?’ to the end.
Following the ‘?’, parameters have a name=value syntax (e.g.: ?amount=250).
When more than one parameter is required, they must be separated by an ‘&’ (e.g.: ?amount=250&frequency=quarterly).
