Payment Workflows

This document outlines the customer-facing payment process, credit card authorization, capture online operations, and credit memo refunds.

1. Customer Checkout Experience

2. Payment Capture Operations

Depending on Payment Action configured in Admin:

• Authorize & Capture: Adyen captures payment immediately upon authorization. Magento automatically creates an invoice with transaction ID set to the Adyen PSP reference.
• Authorize Only (Manual Capture):
  1. Store Admin navigates to Sales > Orders > Select Order > Invoice.
  2. Select Capture Online in the invoice creation page.
  3. The module dispatches a capture request payload to Adyen's /captures endpoint.
  4. Webhook logs receive CAPTURE event and confirm invoice status.

3. Credit Memo & Refunds

When a customer or admin requests a refund:

1. Admin opens Sales > Invoices > Credit Memo.
2. Refund amount is processed online via Adyen's /refunds API.
3. For multi-vendor orders, the system automatically identifies the seller's refunded items and adjusts their payout balance accordingly.
