We create an API integration Module that would allow you to connect any website to our system with easy REST api calls.
We setup an example Donate Now page here. https://webdemo.jlssolutions.com/Donate.aspx
After you enter the donation (on demo you do not need to enter a credit card number) you will get the account number created and the new receipt number.
You can then check for the data in our Fundraisers login. https://jlssolutions.com/QA/1283/fundraisers-smartphone-charge-credit-cards-from-smartphone?show=1283#q1283
