Building A URL With Pre-filled Information

When you link to your donation page in your email service provider (ESP) or marketing platform, you can add dynamic URL parameters to your links.

First, add the URL for the landing page you want your campaign to be associated with. For the sake of this example, the URL would be: https://secure.example.com/samplelandingpage

Next, add the email variable you would like to pass in as a URL parameter. This is the variable you find in your ESP's settings that allow you to pass in a unique email for each donor you send the email to (It's usually something like [%email%], but it varies from one ESP to the other). An example of an email URL parameter would be ?email=[%email%]. This variable gets replaced by your ESP within your URL once you send the email. We require passing through the donor's email address to validate that you know who you're asking to donate.

Add your amount in dollar terms as &amount=5, meaning a $5.00 would be passed through as "5" (Additionally, a $2.50 donation can still be passed through as "2.5").

Your finished URL would look something like this:

https://secure.example.com/samplelandingpageamt1=5&amount=5&recurring=true&firstname=John&lastname=Doe&[email protected]&address=1%20Main&additional[Original]=Thank%20you&bundler_id=12121

As with all URL parameters, always start the first parameter in the URL with ? and all subsequent parameters with &, as shown in the example above. (Note that parameter are case sensitive).

Some notes about pre-filling forms:
​
If the donor user has incomplete information stored within your ESP, the form may not be filled out correctly.
