Common questions
Amazon Selling Partner API (SP-API) is Amazon's API suite for approved sellers, vendors, and application developers. It provides programmatic access to operational data and workflows such as orders, listings, inventory, reports, shipments, and finances.
We connect SP-API with ERP, WMS, OMS, CRM, PIM, accounting, business intelligence, data warehouse, and custom software platforms. The exact data flows depend on your Amazon roles, marketplaces, and approved API access.
Yes. We design integrations for Seller Central workflows and, where the required Amazon APIs or EDI documents are available, Vendor Central operations. We confirm account eligibility and interface availability during discovery.
Yes. We assess the existing MWS workflows, map them to current SP-API operations, replace authentication and data handling, test marketplace-specific behavior, and plan a controlled production cutover.
A focused integration may take a few weeks, while multi-marketplace or multi-system programs can take several months. Scope, Amazon app approval, restricted-data access, workflow count, and testing requirements affect the schedule.
We use least-privilege access, encrypted credential storage, secure token handling, audit logging, data minimization, and role-aware controls. Solutions involving restricted data are designed around Amazon's applicable data protection requirements.
No. SP-API supports commerce operations such as orders, listings, inventory, fulfillment, and financial data. Amazon Ads API supports advertising profiles, campaigns, targeting, budgets, and performance reporting. They can be integrated when operational and advertising data need to work together.
