Wix Product API 2026 – How To Get Product Options Availability

In Wix API, you can get product options availability using Postman based on product 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 and the refresh token in order to request a new access token. 

Step 3: Get product options availability

Before getting product options available, we will get the product ID because that parameter includes in the next call. 

• From Wix dashboard
• Go to “Store products”
• Click on “Products”
• Then click on the product that you want to get the product ID.
• Finally, copy the product ID in the URL. 

We will rely on the product ID and a product option to get the product options available. 

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

Product option = “Size”: “Small”\

Now, we will get the product options available.

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

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

{id} = Product ID.

-HEADER:  ‘Authorization: <ACCESS TOKEN>’

In the body, enter the code.

Payload:

{
    "options": {
        "Size": "Small"
    }
}

Click Send

Response:

As you can see, the Postman returned the product options availability like this.

    "productOptions": [
        {
            "optionType": "drop_down",
