Seller Central data becomes useful to AI when it is connected to the work around each SKU: the order, listing, inventory, and fee estimate in one view. Amazon's Selling Partner API provides that connection after the seller authorizes an app. Building your own means registering as a developer and waiting for Amazon's approval; Unison's app is already approved, so a brand connects once.
Register as a Selling Partner API developer in the Solution Provider Portal before you register an app. A private app for your own seller account needs a professional selling plan. A public app, the kind other brands authorize, has to be listed in the Selling Partner Appstore. Sellers authorize a public app with Login with Amazon.
Amazon reviews the developer profile before a production app can be registered. The docs do not publish a number of days. A private app can be self-authorized after that approval. A public app waits for each seller to approve it on Amazon's consent screen.
Orders, the seller's listings, Amazon's catalog, FBA inventory summaries, merchant-fulfilled quantity, fee estimates, and finances. A fee call returns an estimate. It does not change Amazon's fees.
The Listings Items API can create or edit a seller SKU: title, bullets, description, images, price, and merchant-fulfilled quantity, only where that product type's schema allows the attribute. Amazon assigns the ASIN. A validation preview checks the payload without applying it.
You do not pick an arbitrary FBA fulfillment center. Amazon offers placement options, and you confirm one. A+ content still goes through Amazon's review. Vendor Central and Amazon Ads are different APIs. Order content on the current Orders API is a read.
Amazon publishes a local MCP for developers building on the Selling Partner API. Most of its tools run without credentials. A live call still needs a client id, a client secret, and a refresh token. It is not a Seller Central login you paste into ChatGPT. The Amazon Ads MCP server is a separate product, and it is in open beta.
Bring available Amazon order, catalog, inventory, and payout information alongside relevant data from other connected channels.
Use the shared product and order context to investigate a change, spot a stock concern, or understand performance without stitching together another export.
Use connected product and sales data to prepare an Amazon update for review. Available actions depend on product type, account authorization, and integration scope; agree on review steps before changes are made.
Amazon publishes a local MCP for developers building on the Selling Partner API. Live calls still need Selling Partner API credentials. It does not replace the seller authorizing an app. Amazon Ads has a separate MCP server, in open beta, for ads.
Authorize an app with Login with Amazon, then call the Selling Partner API. ChatGPT or Claude does not receive Seller Central access on its own.
Yes, through the Listings Items API, for attributes the product type allows, including title, bullets, description, images, price, and merchant-fulfilled quantity. Amazon assigns the ASIN.
Amazon reviews the developer profile before a production app can be registered. Amazon does not publish a fixed wait. A private app can be self-authorized after that approval. A public app is authorized by the seller with Login with Amazon.
It should not treat a fee estimate as a fee you can set, and it should not choose an FBA fulfillment center. A+ content still waits on Amazon's review. Ads spend is the Amazon Ads API, not this one.
