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.
