Limitations to QuickBooks API

  • Rate limits can bottleneck data operations. The 500 requests per minute limit may restrict bulk data syncing or real-time integrations for high-volume businesses.
  • No custom object support restricts flexibility. You’re limited to QuickBooks’ predefined data structure, making it challenging to sync unique business processes or custom fields.
  • OAuth token management requires ongoing maintenance. Tokens expire and need refreshing, which can break integrations if not properly handled in your application.
  • Limited historical data access for some endpoints. Certain reports and transaction details may only be available for recent periods, complicating comprehensive data analysis.
