Limits and quotas protect the Google infrastructure from an automated process that uses the Reseller API in an inappropriate way. Excessive requests from an API might result from a harmless typo, or may result from an inefficiently designed system that makes needless API calls. Regardless of the cause, blocking traffic from a specific source once it reaches a certain level is necessary for the overall health of the Google Workspace system. It ensures that one developer's actions can not negatively impact the larger community.
In the unlikely event that your API request fails, you'll receive an HTTP status code response. A status code of 4XX has error information about incorrect input and an HTTP status code of 5XX has error information indicating which API quotas have been exceeded. These responses allow your custom application to detect these errors and take appropriate action.
If the number of requests gets too high, quota errors will occur.
For all errors that are time based (maximum of N things for N seconds per thread), especially the 5XX status code errors, we recommend your code catch the exception and, using an exponential backoff algorithm, wait for a small delay before retrying the failed call. A Reseller API example for one thread is to wait 5 seconds and retry the failed call. If the request is successful, repeat this pattern for the other threads. If the second request is not successful, your application should scale back on the frequency of the request until a call is successful. For example, increase the initial 5 second delay to 10 seconds and retry your failed call again. Also, decide on a retry limit. For example retry a request 5 to 7 times with different delay times before your application returns an error to the user.
|API Limit Categories||Limits|
||This property accepts up to 80 plain text characters.|
|Transfer Token (
||A customer's transfer token is valid for 14 days after it is generated.|
|Maximum number of users for a customer||Depending on your contract, the maximum number of users can either be 750 or the maximum defined in your reseller contract.|
|Unauthorized requests||Google does not allow unauthorized requests to the API. A request is considered unauthorized if no authorization token is provided. For more information, see Authorizing requests.|
|Other Types of Limits||Limitations and Guidelines|
|API Enablement||The API access has to be enabled before making calls to the Reseller API. In your Admin console, go to the Users and groups tab's Settings page and enable the API access toggle. For more API setup information, see Prerequisites.|
|Time format||All date times are in the Epoch format in milliseconds. See an example Epoch converter. This applies to the values for the subscription creation time, a plan's commitment start and end times, and a 30 day free trial's end time.|
