To fulfill your orders, Atomix needs access to your Shopify data (Products, Orders, and Inventory). Follow these steps to create a Custom App and provide the required API credentials.
Step 1: Enable Custom App Development
Log in to your Shopify Admin panel.
Go to Settings (bottom left corner).
Select App and sales channels from the left-hand menu.
Click on Develop apps.
Click Allow custom app development.
Read the warning and click Allow custom app development again to confirm.
Step 2: Create the Atomix App
Click Create an app.
App Name: Enter "Atomix Fulfillment".
App Developer: Select your primary store owner or admin.
Click Create app.
Step 3: Configure Admin API Scopes
Now you must grant specific permissions so Atomix can sync data.
Click Configuration.
Under Admin API integration, click Configure.
Important: You must select Write and Read access for the following scopes:
Assigned fulfillment orders (write_assigned_fulfillment_orders, read_assigned_fulfillment_orders)
Fulfillment services (write_fulfillments, read_fulfillments)
Inventory (write_inventory, read_inventory)
Orders (write_orders, read_orders)
Products (write_products, read_products)
Merchant-managed fulfillment orders (write_merchant_managed_fulfillment_orders, read_merchant_managed_fulfillment_orders)
Click Save at the top right.
Step 4: Install App and Get API Credentials
Click the API credentials tab.
Click Install app and confirm in the pop-up.
You will now see your Admin API access token.
Warning: This token can only be revealed ONCE. Copy it and save it securely.
You will also need the API key and API secret key displayed below the token.
Step 5: Share Credentials with Atomix
Once you have the Access Token, API Key, and Secret Key, please share them with your Atomix Onboarding Manager or send them via Intercom to complete the integration.
