Yas will integrate will Paypal for Payment Gateway,
So there is the need to create an Adapter Service as Paypal Payment service to integrate to Payal.

In this ticket, when Payment Provider is mentioned, we can understand this is the Paypal Payment service

Workflow

Description

• When Payment Checkout object is created by ticket #1121, the CDC Created Event will be deliver to Payment Event Topic,
• Payment Service will handle this CDC_EVENT_PAYMENT_CREATED event to call to Paypal (via Paypal Payment service) to initialize the Checkout Order object (Paypal API Create Order )
• Then the Payment Service will update the Internal Checkout Payment object with { status=PROCESSING, payment_provider_checkout_id = Paypal Order ID}
• CDC_EVENT_PAYMENT_UPDATED will be send to Payment Event Topic then be handled by Order Service to update Associate Checkout { checkout_id, status=PAYMENT_PROCESSING, progress=PAYMENT_CREATED, attributes { payment_id, payment_provider_checkout_id } }
• The Storefront will call interval (each 30s) to Order Service to check State of Checkout and Payment Status
