Rate limit the API method sendverificationcode in Identity Platform

Question

Is there a way to rate limit a certain method for the Identity toolkit API. I want to limit the following API, as I am incurring heavy usage costs from OTP requests.

POST identitytoolkit.googleapis.com/v1/accounts:sendverificationcode

Thank you for the help.

Answer 1

You can refer to Manage quotas and limits documentation in order to create a rate limit in the Identity Platform Console.

From the documentation:

1. In the Google Cloud Console, go to the APIs & Services page.

2. Select the API you want to monitor quotas for. For your case, Identity Toolkit API.

3. Click Quotas.

4. Select the operation you want to edit, then click Edit quotas. You can select multiple operations to edit at a time.

5. Enter a number within the limits set for the operation.

6. Click Submit request to update the operation's quota.
