Connecting a gateway is a mandatory step that must be completed before you will be able to accept donations.
To connect a payment gateway, select My Account, then click on Gateways.
Next, click New Gateway.
From the drop-down menu, select the kind of gateway you are connecting.
Select Heartland Payment Systems
To connect your Heartland Payment Systems Gateway, you'll need your Secret API Key. If you have trouble locating the required information, you can contact Heartland Payment Systems Customer Support by phone at 1 (888) 963-3600 or visit https://www.heartlandpaymentsystems.com/contact-support.
Do a test donation
Do not skip this step! Your unique giving information is included in the welcome email that we sent. Doing a test donation is how you will know if you connection was successful or not. If you receive an error, that is coming from Heartland's system letting you know that your connection was not successful. Let us know if you receive an error during your test donation and we will help you to resolve the issue. You can contact us at firstname.lastname@example.org.
