Before Connecting an Account
Connect a Seller Account
Connect a Vendor (or KDP) Account

When you connect your Amazon account to Perpetua, you need to connect to one or more APIs, including the Amazon Advertising API (AAA) and Marketplace Web Services (MWS).

*️⃣ Connecting the AAA applies to all vendor/seller/KDP accounts, but connecting the MWS will only apply to seller accounts.

Before Connecting an Account

Before you begin, you must meet 2 requirements:

  • You have advertised on this account before

    • If not, create a campaign from Amazon to activate advertising, and come back in 24h

  • The Amazon login that you will use to connect your account has admin permissions on Campaign Manager

    • If not, the account owner will need to grant you View and Edit permissions by following these instructions

If you recently created a Perpetua account and have not yet connected any accounts, you will see this screen. Click Connect Account to get started.


If you already have a Perpetua account, click on your account name and then Add Account.

Next, select your account type.

Connect a Seller Account

To connect a Seller Account, you need to connect the AAA and the MWS.

  1. Name your account.

  2. Click the purple button. You will be taken to Amazon's login page. Once you log in successfully, you will be taken back to Perpetua.

  3. Pick the region.

  4. Connect the MWS using methods a, b or c.

    1. Click the purple button to generate the Seller ID and Authorization Token/MWS Token

    2. If you already have the Seller ID and token, copy and paste it in

    3. If you are an agency connecting an account on behalf of your client, contact us through chat support or hello@perpetua.io for a customized link that you can send to your client (Your client can use this link to easily generate the MWS token to send to you)

      ❎ If you get an error stating that the MWS is invalid, it is likely that the authorization token expired. Please regenerate the token, and try again.

      ❎ If you get an error stating that the MWS Merchant already exists, please contact us on chat support for assistance.

  5. Finally, you will see this screen which means that the account is successfully syncing. All you need to do now is wait. 🥳🚀

Connect a Vendor (or KDP) Account

To connect a Vendor/KDP Account, you only need to connect the AMS (or AAA; the two acronyms are used interchangeably in this context).

  1. Select your country from the drop-down menu.

  2. Sign in to your Amazon account.

  3. Once you sign in, the page will refresh and you will be taken back to Perpetua. After a few minutes of syncing, your accounts will appear. Select your account.

  4. Name your account.

  5. Finally, you will see this screen which means that the account is successfully syncing. All you need to do now is wait. Great! 🎉
