Why do advertising credentials sometimes become invalid?

Amazon Advertising integrations require separate API authorization from standard marketplace connections. Occasionally, advertising credentials may become invalid or expire, which prevents MerchantSpring from retrieving updated advertising metrics.

When this occurs, advertising data may stop updating until the credentials are refreshed.

Common Causes of Advertising Credential Issues

Several factors can invalidate advertising credentials:

• Expired Authorization Tokens
  Amazon periodically requires applications to refresh authentication tokens to maintain secure access.

• Permission Changes
  If the advertising account’s permissions change or access is revoked, the connection may become invalid.

• Account Security Updates
  Password changes, security updates, or changes to account administrators may require reauthorization.

• Amazon API Updates
  Amazon occasionally updates API requirements, which may require integrations to reauthenticate.

Notes: 

• Advertising connections may require separate permissions from marketplace sales data.
• Advertising metrics often update less frequently than sales metrics.
• After reconnection, data may take several hours to fully refresh.
