How to connect ecommerce platforms together

Commerce teams often need information from several platforms to answer a single product or operations question. Connect the systems your business already uses, then put AI to work with the relevant context inside everyday workflows—so your team spends less time gathering information and more time moving work forward.

On your own

Each platform has its own connection and scope.

There is no shared login

Seller Central, Seller Center, the Shopify install, the Faire Brand Portal, the WooCommerce key, eBay OAuth, Etsy scopes, and the TikTok Shop app approval are different grants. A token from one of them does not call the others.

What connecting means

Each integration makes available the data and actions it supports for that account. Fields, permissions, and platform-specific requirements remain distinct and should be confirmed before a workflow is scoped.

What still breaks

Authorizing all eight does not make the quantities match. Shopify stock is per location. Amazon merchant-fulfilled quantity is on the listing. Faire keeps on-hand, committed, and available. The inventory guide is the quantity question.

Ads are separate

Amazon Ads is not the Selling Partner API. Its MCP server is in open beta and needs Ads API credentials. A marketplace connection does not include that ad account unless you connect it too.

With Unison

From disconnected systems to shared company context

Bring the work into context

Connect product, order, and inventory information from the systems in scope, helping teams spend less time gathering details from separate views.

Put AI inside the workflow

Use AI with relevant company data to answer questions and prepare useful next steps, instead of asking teams to repeat context in a disconnected chat.

Scope actions with your team

Supported actions vary by platform and account. Define access, human review, and approval steps for the workflow before any update is made.

Questions

Related questions

Can one authorization connect every ecommerce marketplace?

No. Each marketplace has its own API and its own authorization.

How can connected platforms share useful product context?

Each platform has its own authorization and data model. Unison connects information available through the chosen integrations, while channel-specific fields and supported actions remain distinct.

Which ecommerce channels can be connected?

The integration catalog lists Shopify, Amazon, Walmart, Faire, WooCommerce, eBay, Etsy, TikTok Shop, and additional commerce systems. Available data and workflows vary by integration.

Will connecting a marketplace automatically sync its inventory?

Not by itself. Authorizing the APIs does not choose which quantity is true. That question has its own guide.

Does an ecommerce marketplace connection include Amazon Ads?

No. Amazon Ads is a separate API. The MCP server for ads is in open beta and still needs approved Ads API credentials.
