Define payment process

Starting with Joomla 4, the Seminar Manager uses the Payage Payment Gateway. You can find the "Payage for OSG Seminar Manager" package in the download area. Download and extract it:

1. com_payage must be installed.
2. Afterward, you can optionally install gateways such as Offline (for bank transfers or cash), PayPal Standard, PayPal Checkout (recommended), or Stripe Checkout (recommended).
3. At com_payage -> Gateways, you can then configure and activate the corresponding gateways.
4. At Seminar Manager > Options -> Payment -> Payment API, select "Payage API."

The payment method selection will then automatically appear in the frontend after the booking confirmation on the final page, "Payment Summary."
