Shopify API 2025 – Create, Update, Delete a Customer

Managing customers is very important for each business. From customers’ information, you can run marketing campaigns, send marketing emails, or remind customers to create an account if they don’t have one before to become loyal customers. 

For the reason above, today, Beehexa will help you create, update and delete a customer by Shopify API. This is one of the necessary conditions for your business if you want to manage customers effectively and retain customers for a long time.

Create A Customer Using Postman In Shopify

Step 1: Generate API credentials from the Shopify admin

• • Log in to your Shopify admin

• • Go to Apps – Manage private apps

• • Click Create a new private app

• • In the App details section, enter a name for your app, and an emergency developer email.

• • In the Admin API section, select the areas of your store that you want the app to access

• • Click Save

The Admin API section displays the app’s API key and password when you save the app’s details. 

Step 2: Create a customer using Postman in Shopify

• • Log in to your Postman and create a new workspace

• • Create a new POST with this URL:

https://{username}:{password}@{shop}.myshopify.com/admin/api/{api-version}/{resource}.json

1. 1. {username} – The API key that you generated.

1. 1. {password} – The API password that you generated.

1. 1. {shop} – The name of your development store.

1. 1. {api-version} – The supported API version that you want to use.

1. 1. {resource} – A resource endpoint from the REST Admin API.

Or you can copy this example in the Shopify Admin, remember to change {resource} to {customers}:

https://33a72f01e02987636e1c1a9a4e95c840:[email protected]/admin/api/2021-10/customers.json

• • Paste the URL above.

In the body section, enter this code, then click Send.
