Verify API Quotas: Make sure you are not exceeding any API usage quotas set by Google Drive API. Check your API dashboard to monitor your usage and ensure you have not hit any limits.
Implement API Key: If you haven't already, create an API key and set up proper API restrictions in the Google Cloud Console. Ensure that the API key is used in your website's code to authenticate requests to the Google Drive API.
Use OAuth 2.0 Authentication: Instead of using a public link accessible to anyone ("For anyone with a link"), implement OAuth 2.0 authentication to access the videos. This will provide better control over access and may reduce the chances of Google flagging your requests as suspicious.
Throttle Requests: If your application makes too many requests to the Google Drive API in a short period, it might be considered suspicious behavior. Implement request throttling to limit the number of API requests per second/minute to a reasonable rate.
Implement Error Handling: Handle API errors appropriately in your website's code. If there are errors returned by the Google Drive API, make sure to display helpful error messages to users instead of generic error messages.
Check User-Agent Header: Some applications might get blocked if the User-Agent header in the API requests is missing or incorrect. Make sure your requests include an appropriate User-Agent header.
Verify Video Format: Ensure that the video format you are trying to play on your website is supported by the browsers. Different browsers have different video format support, and using a format that is not supported might lead to loading issues.
Optimize Video Delivery: Consider using video streaming techniques like adaptive bitrate streaming (ABR) or progressive streaming to improve video loading and playback performance.
Test on Different Networks: Test your website and video loading on various networks to ensure that the issue is not specific to your network connection or IP address range.
Reach out to Google Support: If you have tried the above steps and are still facing issues, reach out to Google Drive API support to seek assistance with the specific problem you are encountering.
