Wix API 2024 – How to get inventory variants using Postman

In Wix API, you can get inventory variants using Postman based on inventory item ID.

Today, Beehexa will show you how to do it in this article. 

If this is the first time you make a call in the Postman, you must generate API credentials from the Wix Developers website.

Step 1: Generate API credentials from the Wix Developers’ Website.

Follow the process in Wix API: How to get an access token and refresh the access token? To know how to access Wix API. 

• After creating an app, remember the access token and the refresh token to send requests in the Postman. 

Step 2: Refresh the access token using Postman. 

Wix’s access token is only valid for 5 minutes, so you need to use the refresh token to request a new access token.

Flowing the steps below for refreshing the access token. 

• Log in to your Postman and create a new workspace.
• Create a new POST with this URL:

https://www.wix.com/oauth/access

In the body section, enter the code.

Payload:

{
    "grant_type": "refresh_token",
    "client_id": <APP_ID>,
    "client_secret": <APP_SECRET>,
    "refresh_token": <REFRESH_TOKEN>
}

Body Params:

NAME	TYPE	DESCRIPTION
grant_type	string	Value must be set to “refresh_token”
client_id	string	The App ID as defined in the Wix Developers Center
client_secret	string	The Secret Key for your app as defined in your Wix Developers Center
refresh_token	string	The refresh token issued with the access token

• Then click SEND

Response:

The Postman will return the new access token

Step 3: Get inventory variants using Postman 

Before getting inventory variants, we will get the product’s inventory item ID because that parameter is included in the next call. To have the inventory item ID we must get the product.

• From Wix dashboard
• Go to “Store products”
• Click on “Products”
• Then click on the product that you want to get the product ID. In this case, I will choose this T-Shirt.
• Finally, copy the product ID in the URL. 

We will rely on the product ID to get the product.

Product ID: 61ea866c-1564-401d-aa5e-1a2fc1bf28ed

Now we will get the product

• Log in to your Postman and create a new workspace.
• Create a new GET with this URL:

https://www.wixapis.com/stores/v1/products/61ea866c-1564-401d-aa5e-1a2fc1bf28ed

{id} = Product ID.

-HEADER:  ‘Authorization: <ACCESS TOKEN>’

Click Send 

Response: 

• As you can see, the Postman returned the result like this. Remember to copy this ID for the next step.

Inventory Item ID: 9e157993-ea9b-bfe2-55a1-e5d03e40d712

Finally, we will get inventory variants using Postman.

• In Postman, create a new workspace. 
• Create a new POST with this URL:

https://www.wixapis.com/stores/v2/inventoryItems/9e157993-ea9b-bfe2-55a1-e5d03e40d712/getVariants  

{inventoryId}: inventory item ID

-HEADER:  ‘Authorization: <ACCESS TOKEN>’

In the body, enter the code.

Payload:

{} } 

• Click Send

Response:
