Wix API 2024 – How to create a product category using Postman

In Wix API, you can use Postman to create a product category. Group products into categories (previously called collections) to make it easy for customers to find what they’re looking for. Because after creating the new category, you’ll be prompted to display it on whatever pages you want. 

With the benefit above, Beehexa will show you how to do it in this article today.

If this is your first 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 and refresh tokens 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>
}

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: Create a product category using Postman

Now, we will create a product category.

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

https://www.wixapis.com/stores/v1/collections

-HEADER:  ‘Authorization: <ACCESS TOKEN>’

In the body, enter the code.

Payload:

{
    "collection": {
        "name": "Shoes and T-shirt"
    }
}

Click send

Response: 

As you can see, the Postman returned the data like this.

{
    "collection": {
        "id": "789da22a-23f7-42d9-9578-93dd1e20c836",
        "name": "Shoes and T-shirt",
        "media": {
            "items": []
        },
        "numberOfProducts": 0,
        "slug": "shoes-and-t-shirt",
        "visible": true
    }
}

Step 4: Verify the result
