Google Authentication Error

Access blocked: Sparkbooth's request is invalid

What should I do if I receive an "Access blocked: Sparkbooth's request is invalid" error when trying to authenticate with Gmail, Google Drive, or Google Photos?

If you encounter an error stating "Error 400: invalid_request" while trying to sign in with Google, it may be due to an outdated authentication method used by the software. Please proceed as follows:
- Ensure you are using the latest version of Sparkbooth. As of version 7.1, Sparkbooth has updated its authentication method to comply with Google's standards. - If you are not on version 7.1 or later, please update your software to the latest version to resolve this issue.

What does "Error 400: invalid_request" mean when I'm trying to authenticate Sparkbooth?

This error generally indicates that the request sent to Google by Sparkbooth was invalid. This could be due to several reasons, such as an outdated application version that uses an old authentication method that Google no longer supports.

I see an error that mentions "Out-of-band (OOB) flow has been blocked" when I click on error details. What does this mean?


The "Out-of-band (OOB) flow" is a legacy authentication method that is no longer considered secure by modern standards. Google has blocked this method to protect users. Sparkbooth has adapted to this change by updating its authentication process in versions 7.1 and above.

How do I fix the "out-of-band" error?

To fix the "out-of-band" error, you need to update to the latest version of Sparkbooth. Here are the steps to follow:
- Go to the official Sparkbooth website and download the latest version of the software. - Install the latest version. This should automatically update your current installation. - Try authenticating with Google again. The new version uses an updated authentication method that should resolve the issue.

What if I update Sparkbooth and still get an error while authenticating?

If you have updated to the latest version and you still encounter errors, please check the following:
- Ensure you are connected to the internet and there are no firewall or network restrictions blocking the authentication process. - Double-check that you are using the correct Google account credentials and that you have granted all the necessary permissions for Sparkbooth to access your Gmail, Google Drive, or Google Photos. - If the problem persists, please contact Sparkbooth's technical support for further assistance. Provide them with the error details, screenshots, and any other relevant information to help them diagnose the issue.
