Quotas provide control over how often a client app is\npermitted to invoke an API over a given time interval. In the example below, a Quota policy is\nconfigured to limit apps to 1 request per minute. (While this may not be realistic, it does\nprovide a simple way to see the effects of a policy.)\n\nIn an API proxy configuration, Policy files are stored as XML files under\n`/apiproxy/policies` directory.\n\nFor example, a policy of type Quota called Quota Policy could be created as a file called\n`QuotaPolicy.xml` with the following content: \n\n```text\n\u003cQuota enabled=\"true\" continueOnError=\"false\" name=\"QuotaPolicy\"\u003e\n \u003cAllow count=\"1\"/\u003e\n \u003cInterval\u003e1\u003c/Interval\u003e\n \u003cTimeUnit\u003eminute\u003c/TimeUnit\u003e\n\u003c/Quota\u003e\n```\n\nYou can create a text file by hand, or you can generate the policy from an XML schema. All\npolicies have some settings that are specific to the policy type, and some settings that are\ngeneric across all policies. \nWhen you attach policies in the management UI, the API proxy builder generates the policy instance from the XML schema for the policy type you selected. Therefore, you may see elements in the policy configuration that, for clarity, are not always included in documentation.\n\nAll policies define the following attributes:\n\n- `enabled`: Indicates whether the policy is turned *on* or *off* . Policies can be enabled/disabled at runtime by changing this setting. A policy that has `enabled` set to `false` is not enforced.\n- `continueOnError`: Defines whether the pipeline should continue processing the message if the policy fails. When enforcing quota policies, errors likely indicate that the quota has been exceeded, and, therefore, this attribute should be set to false.\n- `name`: The name that you give to this policy. This name is unique to this policy instance, and it is used to attach the policy to the flow as a processing step.\n\n| **Note:** Except for `name`, you rarely need to modify the default settings for these policy attributes. For this reason, and for clarity, they are often excluded from the policy samples in the documentation.\n\nIn the example above, the elements `Allow`, `Interval`, and\n`TimeUnit` are specific to the Quota policy. These elements provide settings that API\nServices enforces on behalf of an API. Other policy types define their own settings, which you\ncan learn about in the [Policy Reference](/apigee/docs/api-platform/reference/policies/reference-overview-policy)."]]
