Setup AIM on your Event Smart website

Now click the button to activate this payment method and here is an overview of settings on the page.

  • Debug Mode On?: Enables debugging for this payment method. It should be off (set to no) on a live/production site.
  • Open by Default? – This sets this payment method to be pre-selected on the registration checkout page.
    To give your audience more payment options, you can activate multiple payment methods at the same time. However, if you are offering just one payment option, then we recommend that you set that one payment method to be selected by default during registration checkout. That will simplify the check out process for your attendees.

  • Transaction Key: This key is available from your account.
  • Excluded Payment Form Fields : Check a field here to exclude (remove) it from the payment form.

How can I setup a recurring payment or subscription through AIM?
Recurring or subscription payments are not currently supported in the AIM payment gateway.
When I refund a payment, does it also refund through AIM?
Refunds in Event Smart are currently a two step process.
