# Bulk update inventory quantities using inventorySetQuantities **URL:** \ **Category:** New Graphql Product Apis\ **Tags:** Product-Ideas, Product-Tips, Setting-Up\ **Created:** [June 24, 2024, 8:24pm UTC](https://community.shopify.com/t/bulk-update-inventory-quantities-using-inventorysetquantities/334081 "2024-06-24T20:24:48Z")\ **Posts on this page:** 4\ **Page:** 1 ## AI-generated summary Using the inventorySetQuantities mutation (Admin GraphQL 2024-07) to update large numbers of inventory items. The original questions: 1) how many quantity updates can be sent per request, and 2) whether it’s supported by Shopify’s Bulk Operation import. Latest findings: - Bulk Operation: Not supported. A test confirmed inventorySetQuantities cannot run as a bulk mutation via the bulk operations/imports API. - Per-request limit: Not documented in public docs. A community reply indicates a practical limit of 250 quantity updates per request. - Performance report: One implementer updates ~10,000 items by batching 100 per call in about 20 seconds. Implications/notes: - Large-scale updates are feasible by batching standard mutations (e.g., 100–250 per call) rather than using bulk operations. - There is no official confirmation on the exact maximum batch size; 250 is community guidance. Status: Partially answered. Bulk support is ruled out; the precise, officially documented per-request limit remains unclear. The original poster may test and share results later.

Hello there, My app requires to update inventory quantities for (potentially) thousands of inventory items at a time. I am looking at the mutation [inventorySetQuantities](https://shopify.dev/docs/api/admin-graphql/2024-07/mutations/inventorySetQuantities?example=Setting+available+quantity+at+a+location+without+compare-and-swap+%28CAS%29+enabled) which is available in the GraphQL API version 2024-07 and I have a couple of questions that I can’t answer by looking at the public docs: - How many quantities can I update with a single [inventorySetQuantities](https://shopify.dev/docs/api/admin-graphql/2024-07/mutations/inventorySetQuantities?example=Setting+available+quantity+at+a+location+without+compare-and-swap+%28CAS%29+enabled) mutation? The param `quantities` is an array but it does not mention any limits. Would it work with thousands of updates? - Is the [inventorySetQuantities](https://shopify.dev/docs/api/admin-graphql/2024-07/mutations/inventorySetQuantities?example=Setting+available+quantity+at+a+location+without+compare-and-swap+%28CAS%29+enabled) supported as bulk mutation? I do not see it in the bulk mutation list ([https://shopify.dev/docs/api/usage/bulk-operations/imports#limitations)](https://shopify.dev/docs/api/usage/bulk-operations/imports#limitations)) but double checking if it is or will be available soon Thanks in advance! ---

Update: For those interested, I tried to the [inventorySetQuantities](https://shopify.dev/docs/api/admin-graphql/2024-07/mutations/inventorySetQuantities?example=Setting+available+quantity+at+a+location+without+compare-and-swap+%28CAS%29+enabled) in a bulk mutation and it does not work. The only question to answer now is, how many quantities can I update with a single [inventorySetQuantities](https://shopify.dev/docs/api/admin-graphql/2024-07/mutations/inventorySetQuantities?example=Setting+available+quantity+at+a+location+without+compare-and-swap+%28CAS%29+enabled) mutation? I may try that later and will post it. Cheers. ---

I’m using [inventorySetQuantities](https://shopify.dev/docs/api/admin-graphql/2024-07/mutations/inventorySetQuantities?example=Setting+available+quantity+at+a+location+without+compare-and-swap+%28CAS%29+enabled) as well, the limit per request should be 250. Wish it was supported in bulk mutation though. ---

For anyone interested we’re able to update ~10k using this API in batches of 100 in about 20 seconds.
