This topic aims to foster knowledge in our community, mainly regarding the use of GraphQL, and to provide an example of a query that can help retrieve important information related to inventory.
It’s worth noting that we have a learn on the subject at the following link:
As well as the following documentation on Developers:
Where can you find GraphQL in the VTEX Admin?
If your account already has the app installed, it can be found by navigating to “Store Settings” → “STOREFRONT” → “GraphQL IDE”
In this case, since the example proposed here is a Query tied to your store’s inventory, the selected app should be: vtex.inventory-graphql@0.20.0
To check the inventory change logs for a given SKU, simply use the query below, replacing {{skuID}} with the ID of the SKU for which you want to retrieve the change logs, and {{warehouseId}} with the ID of the desired warehouse, which can be found at the following link:
https://{{accountName}}.myvtex.com/admin/shipping-strategy/beta/warehouses
It’s also worth noting that you need to replace the {{accountName}} field with your VTEX account name.
{
productHistory(
sku: "{{skuId}}"
warehouseId: "{{warehouseId}}"
accountName: "{{accountName}}"){
sku
quantity
changelogHistory{
user
date
quantityBefore
quantityAfter
unlimitedBefore
unlimitedAfter
}
}
}
