We have done an integration with HEP Data to provide an easy way for donors to find out if their companies have a matching gift program and how to process those matching gifts. Below is an example:
To set this up, go to the Donations -> Basic Setup -> Display Settings
That will bring up a detailed configuration page. You will need an API Key from HEPData. These vary in cost depending on the size of your race but typically several hundred dollars.
The display is done as a widget. This gives your race a lot of power in terms of placement. With the checkboxes in the setup above, there will be a widget appear when a person completes their donation or donation and registration.
The widget can also be placed on your website, or can be put into your RunSignUp Website in a variety of places.
