This means some services are now linked.\n- The absence of custom batching doesn't affect quota calculation. For example, a batch request containing 500 insert requests will be charged as 500 individual insert method requests.\n- Quota automation for accounts and products remains in place.\n- To determine your current quota usage and limits, including automation and overrides, use the [Quota.list method](/merchant/api/reference/rest/quota_v1/accounts.quotas/list).\n\n| **Note:** For the `accounts.list` method, quota and limits usage are charged for each user, and not for the Merchant Center ID or the advanced account ID. To list several sub-accounts, you should use the `accounts.listSubaccounts` method, which is more suitable for advanced accounts use case.\n\nMethod call quotas\n------------------\n\nMerchant API automatically adjusts call quotas for your\n[`products`](/merchant/api/guides/products/overview) and\n[`accounts`](/merchant/api/guides/accounts/overview) based on your usage.\n\nHere's how we track your quota usage:\n\n- Quotas are per-method. For example, the `get` method has a separate quota from the `update` method.\n- Each request counts once, regardless of its type. For example, we count a `list` request of 250 items once, not as 250 `get` requests.\n- Quota is charged based on the user who makes the API request. If the user is a direct member of an advanced account, the quota will be charged at the level of the advanced account.\n- Quotas apply to the Comparison Shopping Services (CSS) group, CSS, account, or [sub-accounts](/merchant/api/guides/accounts/sub-accounts) against which you authenticate when you make the call. For example, if you authenticate as an [advanced account](https://support.google.com/merchants/answer/188487), calls count against your advanced account's quota, but if you authenticate as one of your sub-accounts, calls count against the sub-account's quota.\n\n\u003cbr /\u003e\n\nThe diagram shows the hierarchy of CSS groups, CSS, accounts, and sub-accounts.\n\n### Check your quotas\n\nTo check the current quota and usage for an account, call\n[`quotas.list`](/merchant/api/reference/rest/quota_v1/accounts.quotas/list)\nwith the `name` of the account.\n\nAutomatic quota only applies to the `products` and `accounts` services. If you\nneed an increased quota for any other service, you're hitting your daily quota\nfor the `products` or `accounts` services, or you need a temporary increase for\nthe `accounts` or products `services`, [contact\nus](/merchant/api/support/get-help) with the following information:\n\n- Your Merchant Center ID\n- The methods you've reached your quota limits on\n- An estimate of the number of calls per day you need for those methods\n- The reason you need a quota increase\n- Whether it's a temporary or permanent increase\n\nWe recommend checking your quotas periodically to ensure you have sufficient\nquota for your implementation, or how your quota is adjusted automatically.\n\n### Errors\n\nIf you exceed the quotas, you receive the following errors:\n\n- Per minute: `quota/request_rate_too_high`\n- Per day: `quota/daily_limit_exceeded`\n\nTo view your quotas and usage, and request a per-day or per-minute quota\nincrease, see [Check your quotas](#check_your_quotas).\n\nThe following errors can't be resolved by automatic quota increases, and require\nyou to [request additional quota of items, feeds or\nsub-accounts](//support.google.com/merchants/contact/additional_items):\n\n- `too_many_items: Merchant quota exceeded`\n- `too_many_subaccounts: Maximum number of sub-accounts reached`\n\nResource representation limits\n------------------------------\n\nThe following limits describe notable restrictions for certain string values and\narray fields within the resource representations used in the Merchant API. These\nlimits are the same for both the Merchant API and their corresponding feature in\nthe Merchant Center.\n\nNote that this list of limits may not be complete. We won't extend these limits.\n\n| Resource | Field | Limit |\n|------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------|\n| [`shippingsettings`](/merchant/api/reference/rest/accounts_v1/accounts.shippingSettings) | Shipping services per country (`services`). Shipping groups per shipping service (`rateGroups`). Labels per shipping group (`applicableShippingLabels`). Subtables per shipping group (`subtables`). Number of rows or columns in a single [rate table](#note2). Length of shipping labels. | 20 20 30 100 150 100 |\n\nThe number of rows or columns in a rate table affects the following array fields:\n\n- Array fields within `rowHeaders` or `columnHeaders`:\n - `prices[]`\n - `weights[]`\n - `numberOfItems[]`\n - `postalCodeGroupNames[]`\n - `locations[]`\n - `rows[]`\n - `cells[]`"]]
