What is Amazon SP-API?

The API that unlocks every workflow in Seller Central.

SP-API is Amazon’s official REST interface for sellers and vendors. Anything you do manually in Seller Central — pulling reports, updating listings, creating shipments, adjusting prices, answering buyers — can be automated through it.

We’ve been shipping on SP-API since day one. Eight years, 50+ tools in production, and zero-downtime MWS → SP-API migrations under our belt.

FAQ

Questions about Amazon SP-API

Short, honest answers — the same ones we give on a discovery call. Don’t see your question? Ask us directly.

  • What can I actually automate with SP-API?

    Everything you do by hand in Seller Central. Concretely:

    • Orders — pull new orders, buyer info and line items in real-time.
    • Inventory — stock levels, reorder alerts, bulk updates via feeds.
    • Reports — schedule 80+ Amazon reports into your DB or Sheets.
    • Pricing — repricing, Buy Box tracking and offer intelligence.
    • FBA — inbound shipment creation, labels and outbound tracking.
    • Ads, finance & messaging — campaigns, settlements, review requests.
  • How is SP-API different from the legacy MWS?

    SP-API is the modern REST/JSON redesign of the XML-based MWS. Cleaner surface, OAuth auth per seller, dynamic rate-limits, real-time webhooks and new endpoints like Request a Review. Most MWS endpoints are deprecated — migrating is no longer optional. We run MWS → SP-API migrations with zero downtime.

  • Do you also cover the Advertising API and PA API?

    Yes. We build on the Amazon Advertising API (Sponsored Products, Brands, Display — reports, campaign CRUD, bidding, targeting) and the Product Advertising API for affiliate/catalog use-cases. We stitch SP-API, Ads API and marketplace APIs (Walmart, eBay, Shopify, TikTok Shop) into a single dashboard when you need it.

  • How fast can you ship a tool and what does it cost?

    Most projects ship in 4–8 weeks at a fixed price scoped in week one. You get weekly Friday demos on your staging, full source code and infra at launch, and an optional maintenance retainer. Book a 15-minute fit call and we’ll give you the number.
