Accept payments through Shopify on your Komerza store. Komerza creates draft orders on your Shopify store and redirects customers to Shopify’s hosted checkout to complete payment.

Prerequisites

  • A Shopify store with an active plan
  • Access to your Shopify Admin dashboard
1

Create a Custom App in Shopify

  1. Log in to your Shopify Admin
  2. Go to SettingsApps and sales channelsDevelop apps
  3. Click Create an app and give it a name (e.g. “Komerza Integration”)
  4. Under ConfigurationAdmin API integration, click Configure and enable the following scopes:
    • write_draft_orders
    • read_draft_orders
    • read_orders
    • write_orders
  5. Click Save
All four scopes are required. Missing any of them will cause connection errors later.

Copy Your API Credentials

  1. In your Shopify app, go to the API credentials tab
  2. Copy the API key and API secret key
Keep these credentials secure — they grant access to your Shopify store’s order data.
3

Connect Shopify to Komerza

  1. In your Komerza dashboard, go to SettingsPayment MethodsShopify
  2. Enter your Shop URL (e.g. mystore.myshopify.com)
  3. Paste the API Key and API Secret from the previous step
  4. Click Save
4

Authorize the Connection

  1. After saving your credentials, click Connect to Shopify
  2. You’ll be redirected to Shopify to approve the app’s permissions
  3. Click Install app on the Shopify authorization screen
  4. You’ll be redirected back to your Komerza dashboard — the connection is now active
The status will show:
  • Active — Everything is connected and working
  • Inactive — Check that your API credentials are correct

How It Works

  1. A customer selects Shopify at checkout
  2. Komerza creates a draft order on your Shopify store
  3. The customer is redirected to Shopify’s hosted checkout to complete payment
  4. Once payment is confirmed, Komerza automatically marks the order as delivered

Managing Payments

  • Refunds — You can issue refunds through Komerza. The refund is processed via the Shopify Orders API and reflected in both platforms.
  • Webhooks — Komerza listens for order and refund events from Shopify to keep everything in sync.

Disconnecting Shopify

Go to SettingsPayment MethodsShopify and click Disconnect. Your existing orders are not affected — only new checkouts will no longer offer Shopify.

Troubleshooting

ProblemFix
”Missing required permissions” errorGo back to your Shopify app settings and make sure all four API scopes are enabled, then reconnect
