Field 'checkoutLineItemsAdd' doesn't exist on type 'Mutation'

[hoangbien]

I am researching to develop an app on shopify. I've used "mutation"

And get the return result: 'Field \'checkoutLineItemsAdd\' doesn\'t exist on type \'Mutation\''
Would you please tell me why not? I am using https://github.com/osiset/laravel-shopify to call the api.
Thank you!
Here query:
$options = new Osiset\BasicShopifyAPI\Options();
$options->setType(true); // Makes it private
$options->setVersion('2021-04');
$options->setApiKey(env('SHOPIFY_API_KEY'));
$options->setApiPassword(env('SHOPIFY_API_PASSWORD'));

$api = new Osiset\BasicShopifyAPI\BasicShopifyAPI($options);
$api->setSession(new Osiset\BasicShopifyAPI\Session(env('SHOPIFY_MYSHOPIFY_DOMAIN'),env('SHOPIFY_API_PASSWORD')));
Log::info($result = $api->graph('mutation {
checkoutLineItemsAdd(lineItems: [{ variantId: "39974961316002", quantity: 5 }], checkoutId: "c324e358f7290a55a83d797a294f382b",
) {
checkout {
id
lineItems(first:2) {
edges {
node {
id
title
quantity
}
}
}
}
}
}'));
Result error:

@hassain Can you help me with this problem? Thank you.

[c10s]

I think you may be trying to run this mutation with the Admin API, when this checkoutLineItemsAdd is only available on the Storefront API.

Thank @c10s for support.  I have solved this problem.

But I have another problem that I don't know how to change product price from webhook before switching to checkout (For example, I want to add a free gift cart product to checkout but with the condition that the price of this product must be 0. Meanwhile I can't add a product from admin with zero price.). Can you give me any advice on this? I really need help with this
