Amazon Selling Partner API — Data Access & Usage Policy
How EcomStride uses Amazon SP-API to deliver services to Amazon sellers — with full transparency on which data roles we access, why we need them, and how we protect client data.
Overview
EcomStride is an Amazon Selling Partner API (SP-API) developer. We are applying for SP-API developer access to programmatically deliver managed services to Amazon sellers. This page documents exactly which SP-API data roles we require, why we need them, and how we use the data — in full transparency for Amazon's review team.
EcomStride's primary service category is Amazon Seller Account Management, encompassing listing optimization, PPC advertising management, FBA operations, inventory management, and account health monitoring — all delivered programmatically through SP-API and operationally through Seller Central on behalf of contracted clients.

Purpose-limited data use. Client Selling Partner data is accessed exclusively for contracted services — never for secondary purposes or internal business intelligence.
No third-party sharing. We do not share, sell, or transfer client Selling Partner data to third parties under any circumstances.
Policy compliance. All data is processed in accordance with Amazon's Data Protection Policy and the Amazon Selling Partner API Terms of Service.
SOC-2 equivalent security. We maintain enterprise-grade security standards for client data, including AES-256 encryption at rest and in transit.

All EcomStride SP-API integrations comply with the Amazon Selling Partner API Developer Agreement and the Amazon Data Protection Policy. Client data is never used to train models, re-sold, or shared with any party outside of the contracted service delivery team.
Process
Client Authorization Process
Before any SP-API access is provisioned, clients go through a transparent five-step authorization workflow.
Client Signs Service Agreement
The client executes our Service Agreement, which includes a Data Processing Addendum specifying exactly which SP-API roles will be accessed and for what purposes.
Client Authorizes EcomStride in Seller Central
Using Amazon's standard OAuth authorization flow, the client grants EcomStride's developer application access to their Seller Central account for the agreed SP-API roles only.
Scoped Access Only
We request only the SP-API role permissions required for contracted services. No broad or unnecessary access is provisioned.
Monthly Access Audits
We conduct internal access audits monthly to confirm that active API credentials correspond only to current active client accounts. Dormant credentials are deactivated.
Full Revocation on Request
At contract end or at any time on the client's request, EcomStride immediately revokes all SP-API tokens and removes the client application from their Seller Central authorized applications list.
