Wix API – How to increase or decrease inventory using Postman

In Wix API, you can increase or decrease inventory by using Postman. Instead of wasting a lot of time changing the inventory of each variant manually, you can do it quickly by using Wix API.

Now, let’s dive into this subject a little deeper to know how to increase or decrease inventory using Postman in Wix API. 

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
Code language: JavaScript (javascript)
refresh the access token in Wix API
  • In the body section, enter the code.

Payload

{ "grant_type": "refresh_token", "client_id": <APP_ID>, "client_secret": <APP_SECRET>, "refresh_token": <REFRESH_TOKEN> }
Code language: JSON / JSON with Comments (json)

Step 3: Get the Product ID and the Variant ID

Product ID

The next call includes the product ID so you need to get that parameter first. 

  • From the Wix dashboard
  • Go to “Store products”
  • and choose “Products”
  • Click on a product that you want to see
  • Copy the product ID in the URL.

Product ID = df19c1f7-07d8-a265-42f8-e8dfa824cc6e

Variant ID

Besides, Beehexa will show you the product variant information and the inventory of that variant so you can see the inventory change in step 4.

  • Scroll down to the “Manage variants” section
get the product ID in the Wix dashboard

As you can see, the variant we will get the ID is Small Black, and it has 2 product variants in stock.

Variants are combinations of product options.

Before increasing the inventory of the variant, you need to get the variant_ID. Because the next call includes that parameter. The variant ID doesn’t show in the dashboard or Wix store. To get the variant ID you need to use API. 

Now we will get the Variant ID.

  • Log in to your Postman and create a new workspace.
  • Create a new POST with this URL:
https://www.wixapis.com/stores/v1/products/{id}/variants/query
Code language: JavaScript (javascript)

{id} = Product ID.

-HEADER:  ‘Authorization: <ACCESS TOKEN>’

In this call, you must ensure that you are granted permission to read the products.
