Amazon’s Sept 3 Reauthorization Deadline: The 5-Minute Checklist

Go to Seller Central > User Permissions > Manage Services. This screen lists every third-party application with access to your account, and for each one, it shows which roles you’ve approved.

For each tool on the list:

1. Confirm it shows as reauthorized, not pending.
2. Check that the roles listed match what the tool actually needs — if a repricer is only approved for read access, its pricing updates won’t go through even after reauthorization.
3. If you don’t recognize a tool, that’s worth investigating separately before September 3 muddies the picture — it may be an old integration you forgot to remove.

If a service shows as pending, the fix is fast: click through the approval, confirm the roles, done. Amazon says the flow takes under a minute per provider once you’re in the screen.

Sellers running two or three core tools tend to remember those. What gets missed is the smaller stuff added a year ago and forgotten: a one-off inventory sync app, a review-request tool, a plugin a former VA set up and never removed. None of those show up on your radar day-to-day — until September 3, when they either get cleanly cut off or, worse, sit in a broken half-authorized state that causes weird behavior nobody traces back to this deadline.

If you manage multiple seller accounts — as an agency or a multi-brand operator — this gets more time-consuming, not less. Every account needs its own pass through Manage Services. There’s no bulk reauthorize across accounts.

Confirm SentryKit shows as reauthorized the same way you’d check any other tool. If it lapses, your alerts don’t error out — they just stop firing, which is exactly the kind of silent gap this deadline is designed to close everywhere else on your account. Once you’ve confirmed SentryKit, use the same five minutes to work through everything else connected to your account.
