This article will show you how to delete a product category from Wix using Postman.

Let’s explore this subject a little deeper. 

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>
}

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: Delete a product category using Postman

Now I will check if this category is in Wix or not.

• Go to the Wix dashboard
• Choose store products 
• Click on categories

As you can see the “T-Shirt” category is in Wix.

Now, let’s get the category ID because the next call includes that parameter.

There are two ways to get the category ID.

The first way you can copy the ID in the response category of the cataloging command

The second way is to query the category and select the category ID you want to delete.

In this article, I will get it the first way. You can read this blog to know more about that: Wix API 2023 – How to create a product category using Postman

I have the category ID = 789da22a-23f7-42d9-9578-93dd1e20c836

Now, we will delete a product category using Postman.

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

https://www.wixapis.com/stores/v1/collections/{id}

-HEADER:  ‘Authorization: <ACCESS TOKEN>’

Then, Click send.

Response: 

As you can see, the Postman returned the empty array.

Step 4: Verify the result

Now, we will verify the category.

• Go to the Wix dashboard
• Choose store products 
• Click on categories

As you can see, the product category has been deleted.
