Unauthorized
Verify the full API key, Bearer header format and key status. The visible prefix in the dashboard is not the full token.
Revoked or lost key
A revoked key cannot be restored. If the full secret was lost, create a new key and update your server configuration.
Rate limits
Slow down request volume, cache non-user-specific inventory appropriately and avoid polling the same endpoint unnecessarily. CPX user-scoped inventory should still be fetched per relevant end user.
