Hii Salesforce Community,.

• How to connect Salesforce Payments to OMS, including the objects, settings, and relationships involved.
• The complete payment lifecycle, including Authorization, Capture, Void, and Refund.
• How payment transactions are associated with Orders and Fulfillment Orders in OMS.
• Whether payment capture is handled automatically by Salesforce OMS when an order is fulfilled, or whether custom automation (such as Flows, Apex, Platform Events, or APIs) is required.
• The standard APIs, payment gateway adapters, and integration points involved in the process.
• A complete end-to-end implementation example, from checkout through order creation, fulfillment, payment capture, cancellation, and refund.
• Salesforce best practices, common implementation challenges, and recommended architecture for a production environment.
