以下详细指南和说明性示例以英语提供。所有示例业务记录均为虚构。
Where PayPal fits
A checkout option approved for the merchant’s actual country, currency and business.
When to choose another approach
Availability, settlement and protection depend on provider terms and the transaction. Do not assume universal protection.
Worked example and evidence
Fictional retailer: confirm payment, release one order and match settlement against the order reference. A dispute is assigned to the merchant’s finance owner.
What you need to supply
Merchant approval, settlement currency, fees, refund/dispute policy and sandbox access.
What acceptance should demonstrate
Verify failed and duplicate payments, signed event handling, refunds and settlement reconciliation.
Running costs and responsibilities
The merchant owns customer disputes and evidence. Assign technical event failures separately.
Technical scope to confirm
Webhook delivery is part of the integration, with validation and idempotent order handling.
A proposal should identify the systems and data, direction of sync, access feasibility, failure handling, named owners and included deliverables. Listing this technology does not imply a prebuilt connector, vendor partnership or included feature.
Who handles customer disputes?
Your nominated merchant representative supplies evidence and makes refund decisions under provider terms. Engineering support can investigate transaction records within its scope.
