# Connect your store (https://sellersheetai.com/docs/start/connect)

> Authorize your Amazon store once, choose which marketplaces sync, add Ads and noon — then every AI client you connect works on it.



You connect a store once, in the SellerSheet app. Every AI client, script and sheet you connect afterwards uses that connection — no Amazon sign-in inside your AI.

<Callout title="Secure by design">
  Amazon's own consent flow does the connecting. SellerSheet never sees your Seller Central password — only the API authorization for the permissions you approve, which you can revoke at any time in Seller Central → Manage Your Apps.

  <Step>
    ### Add the store [#add-the-store]

    **Settings → Stores & Marketplaces → Add store.** Pick the region, the store type (Seller Central or Vendor Central) and the marketplaces, and give the store a name — 1–10 letters, digits or `_`. The name starts every store ref, so a store called `myStore` selling in the US becomes <StoreRef />. Click **Authorize with Amazon**, sign in with the account that owns the store, and approve. You come back to the app with the store listed.
  </Step>

  <Step>
    ### Choose which marketplaces sync [#choose-which-marketplaces-sync]

    Marketplaces are what your plan counts: it includes a number of active marketplaces, shared by your Amazon stores and noon accounts. Change them per store with **Edit markets** on the store's row. Only active marketplaces sync reports and answer your agent; a store with no active marketplace is **paused** — see [Store refs](/docs/mcp-api/store-refs#paused-stores).
  </Step>

  <Step>
    ### Authorize Ads (if you advertise) [#authorize-ads-if-you-advertise]

    Amazon Advertising is a separate consent: use **Ads** on the store's row. Without it, the advertising tools and ad report syncs have nothing to work with — campaign questions come back empty, not broken.
  </Step>

  <Step>
    ### Add noon (optional) [#add-noon-optional]

    **Add a noon account** connects a noon Partners project, with noon's own sign-in or the project's API key. noon refs follow the same shape, such as `myNoon-AE`, and noon marketplaces use the same plan quota.
  </Step>

  <Step>
    ### Let your agent write into Google Sheets [#let-your-agent-write-into-google-sheets]

    Open any Google Sheet → **Extensions → SellerSheet → Open Sidebar** once. This sets up the Drive folders your agent reads and writes, and lets it write reports and dashboards into your sheets.
  </Step>

  <Step>
    ### Check from your AI [#check-from-your-ai]

    Ask your agent "Which stores can you see?" It calls `get_user_context` and lists each store with its `store_refs`, its sync status and your plan. The first reports start syncing right after you connect; most tables have data within hours.

| Account                 | APIs                   | What your agent can do                                                                                               |
| ----------------------- | ---------------------- | -------------------------------------------------------------------------------------------------------------------- |
| Seller Central          | SP-API + Ads API       | The whole tool catalog (more than <Count name="tools" floor="100" /> tools)                                          |
| Vendor Central          | SP-API vendor surface  | The common tools plus purchase orders, shipments and invoices — see [Vendor Central](/docs/mcp-api/workflows/vendor) |

| A store shared with you | The owner's connection | What the owner granted you, per store                                                                                |

## Common connection problems [#common-connection-problems]

| Symptom                                          | Fix                                                                                                                                                          |
| ------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Authorization worked but the wrong store appears | You were signed into another Seller Central account in the browser. Remove the store, sign out of Amazon, add it again.                                      |
| The store shows an authorization error later     | The authorization was revoked or expired. Use **Reauthorize** on the store's row ([how](/help/app/settings/stores#reauthorize)); syncing resumes on its own. |
| Ad tools come back empty                         | Ads was never authorized for that store — **Ads** on the store's row.                                                                                        |
| Your agent can't write to your sheet             | The workspace was never set up — open the sidebar once (step 5).                                                                                             |
| You can't add another store or marketplace       | Your plan's marketplaces are all in use. Upgrade, or turn one off with **Edit markets**.                                                                     |
