Fixing Amazon Sync Errors

Common Amazon Seller Central connection errors in AskBiz and how to fix them.

Error: Authorisation expired or revoked#

Amazon SP-API authorisations expire after 12 months or when revoked in Seller Central.

Fix: Go to Settings → Integrations → Amazon → Reconnect and reauthorise via Amazon Seller Central. While reconnecting, ensure you are logged in as the primary account holder — sub-users with restricted permissions cannot authorise full SP-API access.

Error: Marketplace not supported#

AskBiz supports Amazon.co.uk, Amazon.com, Amazon.de, Amazon.fr, Amazon.it, Amazon.es, Amazon.ca, and Amazon.com.au. Other Amazon marketplaces are not currently supported.

Fix: If you primarily sell on a supported marketplace, ensure you selected the correct marketplace during connection. If your primary marketplace is not on the supported list, contact support@askbiz.co.

Error: Reports API throttled#

Amazon throttles report requests during high-traffic periods. This is an Amazon-side limitation, not an AskBiz error.

Fix: This resolves automatically within 24 hours. AskBiz will retry the failed sync automatically. If throttling persists for more than 48 hours, contact support.

FBA inventory data is missing#

FBA inventory data requires the FBA Inventory permission to be granted during authorisation. If you connected AskBiz before this permission was added, it may be missing.

Fix: Reconnect your Amazon integration via Settings → Integrations → Amazon → Reconnect and ensure all requested permissions are granted during the Seller Central authorisation step.

Advertising data is not appearing#

Amazon advertising data (PPC spend, ROAS, ACoS) requires a separate authorisation from your Amazon Advertising account.

Fix: Go to Settings → Integrations → Amazon Advertising and connect your Amazon Advertising account separately. This is a different connection from your Seller Central connection.
