An error occurred while validating the integration authorization

Hey, @LiveWebinar :waving_hand: Thanks for your question. I have a few basics for you to try to rule out common issues. This will help give the community relevant information about your issue.

  • Check your OAuth configuration – Ensure that your OAuth configuration, including the redirect URL and scopes, match between your HubSpot app and the authorization URL
  • Try a fresh authorization – Sometimes, re-authorizing your application will “fix” things. Try to uninstall and then reinstall your app for one of your test accounts
  • Check your server logs and HubSpot call logs

Thank you! — Jaycee
