It's advised to update products no more than twice daily and sub-accounts once. Quotas are per-method, with `patch` methods impacting both `get` and `update` quotas. The `products` and `accounts` quotas are automatically adjusted, but other services or temporary increases require contacting support. `quotas.list` checks current usage. Errors indicate `request_rate_too_high` (per minute) or `daily_limit_exceeded` (per day). Some resource limits like shipping settings exist.\n"],null,["# Quotas and limits\n\nThe Content API for Shopping imposes strict quotas and limits on some features.\nAll quotas and limits are subject to elimination, reduction, or change at any\ntime, without notice.\n| **Note:** If you need to call `datafeeds.fetchnow` more than once per day, we recommend you use the [`products`](/shopping-content/reference/rest/%0Av2.1/products) service instead to update your product data. We cannot provide a quota increase on `datafeeds.fetchnow`.\n\nQuota policy\n------------\n\nOn average, don't update your products more than twice per day, and\nyour sub-accounts more than once per day.\n\nMethod call quotas\n------------------\n\nThe Content API for Shopping automatically adjusts your\n[`products`](/shopping-content/reference/rest/v2.1/products) and\n[`accounts`](/shopping-content/reference/rest/v2.1/accounts) quotas based on\nyour usage. Your `accounts` usage is based on your sub-accounts limit.\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- `patch` methods count against both your `get` and `update` quotas.\n- Each method call within a `custombatch` counts separately against that method's quota.\n- Calls count against the quota of the account you authenticate as when you make the call. For example, if you authenticate as an [advanced\n account](//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| **Note:** The [`merchantsupport`](/shopping-content/reference/rest/v2.1/merchantsupport) methods always count against the quota for the account whose issues are requested. This might not be the account authenticating the request.\n\n### Check your quotas\n\nTo check the current quota and usage for an account, call\n[`quotas.list`](/shopping-content/reference/rest/v2.1/quotas/list) with the\n`merchantId` of the account.\n\nWe recommend checking your quotas periodically to ensure you have sufficient\nquota for your implementation.\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`,\n[contact us](https://support.google.com/merchants/contact/shopping_api_support_form)\nwith the following information:\n\n- Your Merchant Center ID.\n- Which methods you've reached your quota limits on.\n- An estimation of how many calls per day you need for those methods.\n- The reason you need a quota increase.\n\n### Errors\n\nIf you exceed the Content API for Shopping quotas, you receive the following\nerrors:\n\n- Per minute: `quota/request_rate_too_high`\n- Per day: `quota/daily_limit_exceeded`\n\n| **Note:** Calls that receive `quota/request_rate_too_high`, `quota/daily_limit_exceeded`, or authentication errors don't count towards the daily quota but any other unsuccessful calls are counted towards it.\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 Content API. These\nlimits are the same for both the Content API and their corresponding feature in\nthe Merchant Center. This list of limits may not be complete, and these limits\ncannot be extended.\n\n| Resource | Field | Limit |\n|----------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------|\n| [shippingsettings](/shopping-content/reference/rest/v2.1/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[]`"]]
