1. Background

Yoplanning is a SaaS solution for online management and booking used by leisure and outdoor activity operators. Vakario does not collect, process, or store any credit card data. Payment integration is based exclusively on the Payline by MONEXT system, certified PCI DSS Level 1 (certificate attached).

2. General flow diagram

1. The customer clicks on “Pay” in the Yoplanning booking interface.

2. The Yoplanning server calls the Payline do_web_payment API with the following data:

   • Amount

   • Currency

   • Merchant's VAD number

   • Yoplanning order ID

   • success_url / cancel_url / notification_url

   • Payer's name, first name, email and billing address

3. Payline returns a secure payment URL, to which Yoplanning redirects the customer.

4. The customer enters their banking information on the Payline page hosted by MONEXT.

5. After authorization, Payline redirects the client to the configured URLs and notifies the Yoplanning server.

6. Yoplanning then calls get_web_payment_details to retrieve the payment information and creates the internal order.
