This article will address the following error:
Reports that previously worked now display No Data. An error is displayed in the logs for your data source:
"Task Failed Error: Authorization Error - PMA Error - Please ensure you have the minimum required access to the Amazon Account to get data. See this article: https://support.powermyanalytics.com/portal/en/kb/articles/connecting-to-amazon-seller"
This most often affects Promotions and Fees data, because Amazon protects those with extra permissions. It can appear even if you are a full account administrator.
Cause 1: Your Amazon access expired (most common)
When an administrator grants a user access to an Amazon account, that access expires after one year. Once it lapses, reports that previously worked begin returning the authorization error above.
Fix: Have the Amazon account administrator renew the user’s access on Amazon’s user-permissions page, then reconnect the source in your Hub (go to the Amazon Seller Central account, choose Actions > Reconnect Source) and refresh your report.

Cause 2: The report needs a specific permission (common for Promotions and Fees)
Promotions and fees are restricted data in Amazon Seller Central. Access is controlled at two levels, and both must be in place:
- Your Seller Central user permission. Under Settings > User Permissions > Manage Permissions, confirm Reports > Promotions Performance (View) for promotions, and Reports > Payments and Seller Fee Tax Invoices (View & Edit) for fees.
- Amazon API access. Reconnect the source (Actions > Reconnect Source), approve all permissions in the consent pop-up, then refresh.

Amazon serves the Promotions Performance report only to accounts enrolled in Amazon Brand Registry. If your account is not brand-registered, promotions data will not come through even when the permissions above are set correctly.
Cause 3: A field combination Amazon does not support
Some fields cannot be reported together. Most commonly, the Quantity field cannot be used in the same table as a Fee field (this produces incorrect fee values). Remove one and refresh.
Still seeing the error?
If the report still fails after renewing access, confirming the permissions above, and reconnecting the source,
submit a ticket and include the exact field or report that is failing, a screenshot of the error, the name of your Hub and the Amazon account, and the date the data last populated correctly.
