Today, we’re focusing on an essential, yet sometimes overlooked aspect of Magento 2: getting a product by SKU using GraphQL. Understanding how to accurately and efficiently retrieve product details using SKU, or Stock Keeping Unit, is crucial for managing any e-commerce platform.

Whether you are a seasoned developer looking to sharpen your skills or a newbie trying to navigate the exciting world of Magento 2, this article will serve as a handy guide, breaking down the process into easy-to-understand steps.

Get A Product By SKU With GraphQL

Endpoint: “http(s)://yourdomain.com/graphql”

Method: POST

Syntax:  products(
    search: String
    filter: ProductFilterInput
    pageSize: Int
    currentPage: Int
    sort: ProductSortInput
): Products

Request example:

{
  products(
    filter: { sku: { like: "24-WB%" } }
    pageSize: 20
    currentPage: 1
    sort: { name: DESC }
  ) {
    items {
      sku
    }
    filters {
      name
      filter_items_count
      request_var
      filter_items {
        label
        value_string
        items_count
      }
    }
  }
}

Response:

{
    "data": {
        "products": {
            "total_count": 26,
            "items": [
                {
                    "name": "BUNDLE: Tiny Round \"Design Your Own\" Children's Necklace for Girls (50+ Optional Charms & FREE Engraving)",
                    "sku": "Tiny Round",
                    "price": {
                        "regularPrice": {
                            "amount": {
                                "currency": "USD",
                                "value": 439.78
                            }
                        }
                    }
                }],
            "page_info": {
                "page_size": 25,
                "current_page": 1
            }
        }
    }
}

For example:

Then, you write down the endpoint and your request:

After that, you can click run to send a request to the server.

Bonus: Get A Product With REST API

You can use a tool to access the API. In this situation, we will use Postman.

We need to get the access token of the admin user to get a product.

Endpoint: “http(s)://yourdomain.com/rest/V1/integration/admin/token”

Method: POST

Request:

{
	"username" : "string",
	"password" : "string"
}

Response: “token” (string)

For example:

In the first step, we get the access token of the admin user to get a product.

Endpoint: “http(s)://yourdomain.com/rest/V1/integration/admin/token”

Method: POST

Request:

{
	"username" : "string",
	"password" : "string"
}

Response: “token” (string)

For example:

Now, we have the access token. Let begin to get a product from API.

Endpoint: “http(s)://yourdomain.com/rest/V1/ products/:sku”

Method: GET

Request: sku.

Header: Authorization: Bearer (Token)

Response: token(string)

For example:

You need to check the access token. If it is correct, the API will return Product’s Information.

If the access token is incorrect, the API will return the error message like the following:

This is a process to get a product from REST API.

We hope that this instruction will help you get a product through API easily.
