Evidence-safe migration rules
Do not claim a native integration until a real Shopify test proves the event and timestamp arrive as expected. Confirm product variants, line items, refunds, fulfillment status, subscription state, consent source, and identity merges. Keep marketing, service, and transactional messages separate; email permission does not automatically transfer to SMS.
Attribute revenue consistently and report incremental evidence separately from platform-reported revenue. If the alternative cannot reproduce a critical flow, downgrade the requirement or keep a bounded specialist tool rather than forcing a risky all-in-one migration.
Official checks and internal reading
Start with the consent checklist, pricing-model guide, and attribution guide. Every review above links to the vendor’s current page; record access date, plan name, limits, add-ons, data retention, and cancellation terms.
