Donation URL params

What are URL params?

URL params (short for parameter) are a way of sending additional information via a URL. URL params are appended to the path of a URL and begin with a ? symbol, and each parameter is typically separated by a & symbol. Here is an example: http://cool-animals.com/search?country=australia&environment=desert. (You can read more about URLs here).

The CommitChange donation page uses URL params to set things like custom amounts and campaign IDs.
