Square Payment Addon for Modern Events Calendar

The Square Payment Addon for Modern Events Calendar (MEC) is a premium addon developed by Webnus that connects MEC's booking and ticket sales system with the Square payment gateway. It is designed for event organizers, small businesses, non-profit associations, and venue managers who already use Square for their in-person sales and want to unify their online and offline transactions on a single platform.

This addon allows attendees to pay with credit or debit cards directly on your website, without being redirected to external pages. The payment process is natively integrated into MEC's booking flow, reducing friction at the critical moment of purchase and significantly improving conversion rates. By eliminating intermediate steps, users complete their bookings faster and with more confidence.

Key features include easy connection to your Square account by entering API credentials (Application ID, Access Token, and Location ID), the ability to switch between Sandbox mode for testing and Production mode for real transactions, and automatic synchronization of payment status with MEC booking records. Additionally, the addon sends automatic confirmation emails after each successful payment and centralizes all revenue in the Square dashboard, simplifying accounting reconciliation and financial tracking.

Security is a priority: Square complies with PCI DSS standards and offers advanced fraud detection mechanisms, ensuring protected transactions for both the organizer and the attendee. The addon works alongside other gateways like Stripe and PayPal, which are already included in MEC, thus offering your users multiple payment options and a more satisfying shopping experience.

Configuration is accessible even for users without technical knowledge: simply fill in the credential fields in MEC Settings > Booking > Payment Gateway > Square. The addon requires the Pro version of Modern Events Calendar and a Square developer account to generate API keys. With quick installation and an intuitive panel, this addon is the ideal solution for those looking to collect payments securely, professionally, and without complications at their events.
