Amazon authorization
Sellers stay in control of their data access.
1
Connect Amazon store data through Selling Partner API authorization.
2
Connect Amazon Ads data through Login with Amazon authorization.
3
Review connected marketplaces, advertising profiles, sync status, and access health.
Sellers do not share Amazon passwords, client secrets, or API credentials with Sailwyn. Authorization can be revoked through Amazon or by contacting our support team.
Security
Designed around least-privilege access.
Our first release focuses on non-PII business, advertising, inventory, listing, and financial reporting data. Write actions are limited to advertising budget and bid updates and sending Amazon's standard review requests for eligible orders — each requires explicit seller approval and is fully audit-logged. Buyer names, phone numbers, addresses, shipping labels, and tax invoice data are not part of the product scope.
Token protection
Authorization tokens are stored encrypted and are never shown in the user interface, reports, or logs.
Tenant separation
Seller accounts, advertising profiles, sync jobs, reports, and operational logs are separated by account.
Auditability
Account access, authorization changes, sync activity, and every budget or bid change are logged with account, timestamp, actor, and result details.
Data use limitation
Data from an authorized Amazon account is used only to provide the service to that account. It is never sold, shared with other customers, or used for any unrelated business purpose.
