The Drive API returns two levels of error information:
- HTTP error codes and messages in the header.
- A JSON object in the response body with additional details that can help youdetermine how to handle the error.
Drive apps should catch and handle all errors that might be encountered whenusing the REST API. This guide provides instructions on how to resolve specificAPI errors.

Appid Patch V3
A backendError occurs when an unexpected error arises while processing therequest. This can be caused by a variety of issues, including a request's timingoverlapping with another request or a request for an unsupported action, such asattempting to update permissions for a single page in a Google Site instead of thesite itself.
Appid Patch V3 Download
To fix this error, use exponential backoff to retrythe request. Following is a list of 500 errors:
- 502 Bad Gateway
- 503 Service Unavailable
- 504 Gateway Timeout
Retry failed requests to resolve errors
You can periodically retry a failed request over an increasing amount of time tohandle errors related to rate limits, network volume, or response time. Forexample, you might retry a failed request after one second, then after twoseconds, and then after four seconds. This method is calledexponential backoff and it is used to improve bandwidth usage and maximizethroughput of requests in concurrent environments. When using exponentialbackoff, consider the following:
- Start retry periods at least one second after the error.
- If the attempted request introduces a change, such as a create request, add acheck to make sure nothing is duplicated. Some errors, such as invalidauthorization credentials or 'file not found' errors, aren't resolved byretrying the request.

Request additional quota
If you believe you need additional quota:
- Visit the Google API Console
- Select your project.
- Click the Quotas tab.
- Request additional quota.
Only request additional quota if your application exceeds the Drive API courtesylimit or the per-user limit. If exceeding the per-user limit, try to optimizeyour application code to make fewer requests.
