Its very interesting.
I tried to change this in the admin UI i. e. https://admin.shopify.com/store/xxx/products/yyy
Then we have this request:
{
"operationName": "ProductSaveVariantsUpdate",
"variables": {
"productId": "gid://shopify/Product/xxxx",
"variantsToBulkUpdate": [
{
"id": "gid://shopify/ProductVariant/xxxx",
"showUnitPrice": true,
"unitPriceMeasurement": {
"quantityValue": 500,
"quantityUnit": "ML",
"referenceValue": 1,
"referenceUnit": "L"
}
}
]
},
"query": "mutation ProductSaveVariantsUpdate($productId: ID!, $variantsToBulkUpdate: [ProductVariantsBulkInput!]!) {\n productVariantsBulkUpdate(\n productId: $productId\n variants: $variantsToBulkUpdate\n ) {\n userErrors {\n field\n message\n __typename\n }\n __typename\n }\n}\n"
}
Well, yea, looks as easy as possible.
... But ...
Simple Node Shopify GraphQL...
const shopify = shopifyApi({
apiKey,
apiSecretKey,
adminApiAccessToken,
apiVersion,
isEmbeddedApp: false,
scopes: ['read_products', 'write_products', 'write_inventory'],
hostName: shop,
future: {
lineItemBilling: true
}
});
await this.client.request(`mutation(
$productId: ID!,
$input: ProductVariantsBulkInput!) {
productVariantsBulkUpdate(productId: $productId, variants: [$input]) {
userErrors {
field
message
}
}
}`,
{
variables: {
productId: xxxx,
inventoryItemId: yyyy,
input: {
showUnitPrice: true,
unitPriceMeasurement: {
quantityValue: 500,
quantityUnit: "ML",
referenceValue: 1,
referenceUnit: "L"
}
}
}
});
I mean it also looks very simple.
But executed it results in ...

"networkStatusCode": 200,

}
},
"problems": [
{

],
"explanation": "Field is not defined on ProductVariantsBulkInput"
},

"explanation": "Field is not defined on ProductVariantsBulkInput"
}
]
}
}
],

}
}
So the only way to solve that is via browser automation. Very sad & bad but ... Shopify 😀
