Name the records that must move
An integration is not just a logo on a website. Specify whether the connection exchanges products, stock, orders, customers, invoices or payments. For each record, name the system of record and the permitted direction of updates. An order identifier should remain traceable across both sides.
Map an ordinary transaction
Follow one order from acceptance through fulfilment and financial reconciliation. Identify when stock changes and which event creates an invoice. Confirm tax, units, discounts and partial shipments with the people responsible for them. A technically successful request can still create an incorrect business record.
Test retries and exceptions
Disconnect a test connection, send the same event twice and change an order after it has been imported. Check duplicate prevention, retry limits, reconciliation reports and the person alerted to a failure. Agree how historical records are imported without accidentally repeating stock or financial effects.
Confirm scope and permission
Shopify, Xero, QuickBooks and other platforms have their own interfaces, permissions and plan constraints. A VasKem connection to any named platform must be demonstrated or separately scoped in writing. Do not assume a native connector, automatic two-way sync or unrestricted API access is included. Use least-privilege credentials and never send secrets in an initial enquiry.
