Setup and Configuration

An account with MiGS is needed to accept payments via MiGS.

A dedicated SSL certificate is recommended to make registration checkout and other areas of your website more secure.

Login to your WP-admin (WP Dashboard) and go to Event Espresso –> General Settings –> Payment Methods. Once on the Payment Methods screen, click on MiGS and click on the button to activate the payment method.

Below are the available fields and explanations for each field.

Name – This is the name of the payment method.
Description – This description is shown during registration checkout.
Admin-Only Name – This is a name of the payment method that will only be shown in the WP Dashboard (WP-admin).
Admin-Only Description – This description is used only in the WP Dashboard (WP-admin).
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.

I configured MiGS and payments are not being processed. Can you help?
Double-check that you are using your API credentials for production (live) mode which are different than your login information for your MiGS account. Also, ensure that there is no extra spacing before or after the credentials in the payment methods screen of Event Espresso 4.

When I refund a payment, does it also refund through MiGS?
Refunds in Event Espresso 4 are currently a two step process. First, apply the refund through the transactional details screen of Event Espresso in your WP-admin (WP dashboard). Then login to your MiGS account and process the refund.

How can I setup a recurring payment or subscription through MiGS?
Recurring or subscription payments are not currently supported in the MiGS payment gateway.

Is an SSL certificate needed for MiGS?
A dedicated SSL certificate is recommended if you are accepting payments on your website.

Do I need to be PCI compliant?
Compliance with the Payment Card Industry Data Security Standards (PCI DSS) is required if you are processing, storing, or transmitting credit card data. Event Espresso recommends using a dedicated SSL certificate on your website.
