Use case
Ecommerce warmup
Stores that run many buyer identities care about coherent sessions more than flashy fingerprint scores. Multilogin keeps jars apart so QA buyers and agency test accounts don’t inherit each other’s carts.
Before checkout stress
- Sticky residential/mobile proxy matched to the story — proxy.
- Timezone/language snap — TZ.
- Browse naturally first — warmup checklist.
- Never paste unrelated cookies into a money profile — cookies.
Automation
Use Playwright for inventory/QA checks, not for carding or payment fraud. Pro+ API: guide.
Follow merchant and network rules. Affiliate disclosure applies.
What this is not
Not carding, not synthetic identity fraud, not “bypass merchant risk” theater. Legitimate multi-brand QA, marketplace operators, and agency test buyers separate sessions so bugs in one cart don’t poison another.
After first purchase path works
- Log profile UUID + proxy geo next to each test SKU.
- Keep automation on inventory/price checks — humans on payment UI when policy is ambiguous.
- If you also run ads: don’t reuse ecommerce buyer profiles as ad-account profiles — ads playbook.
