Amazon Connection & Authorization

Summary: How to authorize Jinnify with Amazon Seller Central, confirm the connection, reconnect when access expires, and fix common OAuth problems.

Before you begin

  • Sign in to the correct Amazon Seller Central account (especially if you manage clients)

  • Prefer an account owner or admin user who can authorize third-party apps

  • Know which marketplace you care about first (each marketplace is its own store row in Jinnify)

Recommended path: start from Jinnify

Connect your store from Jinnify

Most sellers should connect from the app (not only from the Appstore):

  1. Sign in to app.jinnify.ai.

  2. Open Your stores: top bar → workspace menu → Manage workspaces & connections,
    or use Connect store from the store menu in the top bar.

  3. Choose Connect store → Amazon.

  4. Read the short explainer (what happens next; +5,000 Jinnify credits when you connect).

  5. Click Continue to Amazon.

  6. In Seller Central, review permissions and approve access for the intended seller account.

  7. Return to Jinnify (automatic redirect when possible).

  8. Confirm the store appears under Your stores / the top bar store list.

Authorization Screen

Amazon is available today. TikTok Shop, Walmart, and eBay show as Soon.

Optional path: Selling Partner Appstore

  1. Sign in to Seller Central.

  2. Open Apps and ServicesSelling Partner Appstore.

  3. Search for Jinnify, open the app page, and authorize.

  4. Complete the flow and return to Jinnify to confirm the store is listed.

If you started on the Jinnify website, you may land on the app page or go straight into authorization.

Who should authorize

Use the main Seller Central owner or a trusted admin for the first connection when:

  • Your team uses multiple sub-users

  • You manage several marketplaces

  • Internal policy restricts who may approve third-party apps

  • The store belongs to a client

If a non-admin fails mid-flow, retry with a higher-permission user.

How to verify the connection is healthy

You are in good shape when:

  • The store appears under Your stores and in the top bar (if Active, not paused)

  • The expected marketplace label is visible (for example United States)

  • Status is not Reconnect needed, Onboarding Failed, or stuck on Awaiting first sync forever

  • Listings begin to appear on Your listings after sync

Authorization success does not mean data is instant. Initial sync can take additional time.

Statuses you may see

Status

Meaning

Awaiting first sync

Connected; waiting for first data pull

Synced just now / Synced Nh ago / Synced Nd ago / date

Relative last sync time on Your stores

Syncing

Data load in progress

Reconnect needed

Amazon access expired; connect again from Connect store → Amazon (list / top bar), not only Manage

Onboarding Failed / Initial onboarding failed

First setup did not finish; Manage shows Reconnect store

Paused

Turned off in Jinnify; hidden from the store selector; Amazon not disconnected

Sandbox

Demo store (Jinnify Demo Catalog), not a production SP-API connection

Connected / Connection Failed

Labels you may see on Manage connection status

Reconnect when access expires (Reconnect needed)

Amazon access can expire or be revoked.

  1. On Your stores (or the store menu), choose Connect store → Amazon.

  2. Complete Seller Central approval again for the same intended account.

  3. Confirm status recovers and sync progresses.

There is no separate reconnect button on Manage for the simple expired-token case. Use Connect store → Amazon again.

Reconnect after Onboarding Failed

  1. Open Manage on the store.

  2. Click Reconnect store.

  3. Complete Amazon authorization again.

  4. If it still fails, contact support with your account email, marketplace, seller ID, and screenshots.

Wrong seller account

  1. Open ManageRemove this store → confirm (or pause if you only want to hide it).

  2. Sign out of the wrong Amazon session or switch Amazon user.

  3. Run Connect store → Amazon again and approve the correct account.

  4. Confirm the seller ID and marketplace on Manage.

Disconnect safely

  1. Finish or cancel in-flight workflows that need that store.

  2. ManageRemove this storeRemove store.

  3. Optionally revoke the app under Seller Central third-party apps.

Disconnecting stops future Jinnify sync and publish for that store. It does not undo listing changes already accepted by Amazon. The sandbox demo store cannot be removed by hand; Jinnify removes it after a real store connects.

Multi-marketplace sellers

If the same seller sells in more than one country, each marketplace appears as its own row. You can put them in different workspaces. Pause marketplaces you do not want in the top bar without disconnecting Amazon.

Common errors

Problem

What to try

Cannot authorize

Correct Amazon user; admin permissions; clean browser session; disable blockers that stop redirects

Flow finished but no store in Jinnify

Wait and refresh Your stores; retry connect; confirm OAuth returned to app.jinnify.ai

Authorization expired

Connect store → Amazon again

Wrong store

Remove, switch Amazon account, reconnect

Marketplace missing

Confirm it exists on that seller account; reconnect correct account; ask support about support scope

Loop or repeated failure

Capture Amazon and Jinnify screenshots and contact support

Credits when you connect

Connecting a real Amazon store grants +5,000 Jinnify credits (in addition to the trial starter balance). The connect explainer in the app calls this out before Continue to Amazon.

What success looks like

  • Correct seller account and marketplace visible in Jinnify

  • Status past first sync without auth errors

  • You can open Your listings for that store

  • You can publish from Create when credits and required fields allow

When to contact support

Contact support if authorization loops, sync never starts while status looks active, the wrong seller keeps attaching, or onboarding fails after Reconnect store.

Include: Jinnify email, marketplace, seller ID, exact error text, screenshots of Amazon and Jinnify, approximate time (with timezone).
