このドキュメントでは、Google Tag Manager API の制限と割り当てについて説明します。
概要
Google タグ マネージャーは数百万のサイトで使用されています。そこで、システムが処理能力を超えるデータを受信することを防ぎ、システム リソースを安定的に配布するために、一定の制限事項が設けられています。ポリシーについては以下で説明しますが、これらは予告なく変更される場合があります。
割り当ての取得
割り当てを取得するには、Google API Console でアプリケーションを登録する必要があります。未登録の割り当ては許可されません。新しいアプリケーションを登録すると、プロジェクト内で識別するための固有のクライアント ID が割り当てられます。
クライアント ID でアプリケーションを識別する方法については、API Console ガイドのキー、アクセス、セキュリティ、ID のセクションをご覧ください。

To protect the system from\nreceiving more data than it can handle, and to ensure an equitable\ndistribution of system resources, certain limits have been put in place. Our\npolicies are as follows and are subject to change.\n\nObtaining Quota\n---------------\n\nYou must register your application in the\n[Google API Console](https://console.cloud.google.com/) to receive any quota; no\nunregistered quota will be allowed. When you register a new application, you\nare given a unique client ID to identify each application under that project.\nRead the [Keys, access, security, and\nidentity](/console/help/using-keys)\nsection of the API Console guide to learn more about how client\nIDs identify applications.\n\n### General Quota Limits\n\nThe following quota limits apply to all requests made to the\n[Tag Manager API](/tag-platform/tag-manager/api/v2):\n\n- 10,000 requests per **project** per day.\n- 0.25 queries per second (QPS) per **project**.\n\nThese quotas are independent of those you can set in the\n[API Console](https://console.cloud.google.com/). If the\nyou set the project's **per-user limit** above 0.25 QPS, the\nGoogle Tag Manager quota policy will still take effect and limit per-project\nrequests to 0.25 QPS.\n| **Note**: Daily quotas refresh at midnight PST. QPS quotas are enforced on a 100 second sliding window (i.e. 25 requests per 100 seconds).\n\nExceeding Quota Limits\n----------------------\n\nIf quota is exceeded, Google Tag Manager API returns an error for\nadditional requests: HTTP status code `403 Forbidden` and\na message indicating that the specific account has insufficient\nquota to proceed.\n| **Note** : You can apply for an increased quota by clicking **Edit Quotas** in the [API Console](https://console.cloud.google.com/) and filling out the *apply for higher quota form* to have your request considered."]]
