Laravel + Shopify inventoryBulkAdjustQuantityAtLocation - php

Question

I'm using following package : 'osiset/Basic-Shopify-API' and need bulk update products by location.
It's only possible with GraphQL. This function should work :
inventoryBulkAdjustQuantityAtLocation Shopify documentation
$shop = 'example.myshopify.com';
$token = 'shppa_admin_api_token';
/ Create options for the API
$options = new Options();
$options->setVersion('2020-04');
// Create the client and session
$api = new BasicShopifyAPI($options);
$api->setSession(new Session($shop, $token));
$products[0]['inventoryItemId'] = '33125243617303';
$products[0]['availableDelta'] = 2000;
$result = $api->graph(
'mutation inventoryBulkAdjustQuantityAtLocation($inventoryItemAdjustments: InventoryAdjustItemInput!,$locationId: ID!)
{inventoryBulkAdjustQuantityAtLocation(inventoryItemAdjustments: $InventoryAdjustItemInput, locationId: $locationId) {userErrors {field message } inventoryLevels { id }}}',
['inventoryItemAdjustments' =>
$products
],
);
But I don't understand how to use it. Could anyone help me ?

Answer 1

Now it works. It's a challenge to understand GraphQL queries if you never used them before.
Here are some more information :
https://www.shopify.com/partners/blog/multi-location_and_graphql
$locationId = "gid://shopify/Location/1";
$inventoryItemAdjustments1['locationId'] = $locationId;
$inventoryItemAdjustments1['inventoryItemAdjustments']['inventoryItemId'] = 'gid://shopify/InventoryItem/1';
$inventoryItemAdjustments1['inventoryItemAdjustments']['availableDelta'] = 500;
$result = $api->graph('mutation inventoryBulkAdjustQuantityAtLocation($inventoryItemAdjustments: [InventoryAdjustItemInput!]!, $locationId: ID!)
{inventoryBulkAdjustQuantityAtLocation(inventoryItemAdjustments: $inventoryItemAdjustments, locationId: $locationId) {userErrors { field message }}}',
$inventoryItemAdjustments1
);

Answer 2

Not so good examples (hardcoded values, aliases - not real life examples) ... graphql variables should be used and they should match mutation requirements ('root' parameters), in this case locationId and inventoryItemAdjustments (array of objects).
You can test this mutation in graphiql/playground using 'query variables' defined like this:
{
locationId: "gid://shopify/Location/1",
inventoryItemAdjustments: [
{
'inventoryItemId': 'gid://shopify/InventoryItem/1',
'availableDelta': 500
},
{
'inventoryItemId': 'gid://shopify/InventoryItem/2',
'availableDelta': 100
}
]
}
... so using php (associative arrays are encoded to json as objects - explicitely declared for readability) it should look more like this:
$locationId = "gid://shopify/Location/1";
$inventoryItemAdjustments = [];
$inventoryItemAdjustments[] = (object)[
'inventoryItemId' => 'gid://shopify/InventoryItem/1',
'availableDelta'] => 500;
];
$inventoryItemAdjustments[] = (object)[
'inventoryItemId' => 'gid://shopify/InventoryItem/2',
'availableDelta'] => 100;
];
$variables = (object)[
'locationId' => $locationId;
'inventoryItemAdjustments' => $inventoryItemAdjustments
];
$result = $api->graph('mutation inventoryBulkAdjustQuantityAtLocation($inventoryItemAdjustments: [InventoryAdjustItemInput!]!, $locationId: ID!)
{inventoryBulkAdjustQuantityAtLocation(inventoryItemAdjustments: $inventoryItemAdjustments, locationId: $locationId) {userErrors { field message }}}',
$variables
);

Answer 3

I would like to show another library that uses this and expand on the last example.
I am using a slightly different library for graphql:
https://github.com/Shopify/shopify-php-api/
Updating the inventory like it was posted here shows a [statusCode:GuzzleHttp\Psr7\Response:private] => 200
So it seems to work but does not reflect in updated inventory. :(
Checking at /admin/products/inventory?location_id=62241177806&query=F11_27781195
would not show the new inventory.
I am using the inventoryid correctly (not product or variantid).
$inventoryItemAdjustments = array();
$inventoryItemAdjustments[] = (object)[
'inventoryItemId' => 'gid://shopify/InventoryItem/43151435235534',
'availableDelta' => 500
];
$inventoryItemAdjustments[] = (object)[
'inventoryItemId' => 'gid://shopify/InventoryItem/43151435268302',
'availableDelta' => 500
];
$variables = array(
'locationId' => ConfigClass::$locationId,
'inventoryItemAdjustments' => $inventoryItemAdjustments
);
$graphqlquery='mutation inventoryBulkAdjustQuantityAtLocation($inventoryItemAdjustments: [InventoryAdjustItemInput!]!, $locationId: ID!)
{inventoryBulkAdjustQuantityAtLocation(inventoryItemAdjustments: $inventoryItemAdjustments, locationId: $locationId) {userErrors { field message }}}';
$response = $client->query(['query' => $graphqlquery, 'variables' => $variables]);
Deleting a product works (and is a good test if the library is initialized well):
$query = <<<QUERY
mutation {
productDelete(input: {id: "gid://shopify/Product/6975310463182"})
{
deletedProductId
}
}
QUERY;
$response = $client->query(["query" => $query]);
print_r($response);
die;
