Install Paystand for BigCommerce

Important considerations

• Paystand is not listed as an official BigCommerce app. Installation requires manual setup using your store’s WebDAV access and Paystand API credentials.
• Follow this guide carefully to connect your BigCommerce store to Paystand and enable your custom checkout.

The Paystand plugin allows you to accept digital payments—including ACH, Bank Transfers, and Credit Cards—directly in your BigCommerce store using the Paystand zero-fee payment network.

Setup is completed in two parts:

1. Connect BigCommerce to Paystand by entering API credentials

2. Install the Paystand Custom Checkout by files via WebDAV

Part 1: Connect BigCommerce with Paystand

Step 1: Log in to BigCommerce

Go to your BigCommerce Admin Dashboard and sign in with your store credentials

Create a store-level API account

1. Go to Advanced Settings > API and click Store-level API accounts
   

2. Click Create API Account
   

3. Enter a recognizable name (for example, Paystand Integration)
   

4. Assign the following permissions

Save your changes
BigCommerce automatically downloads a .txt file containing your Access Token, Client ID, Client Secret, and API Path

Tips

• Refer to the permission screenshots in the Paystand setup documentation for a visual reference.
• Keep the downloaded file in a secure location — you’ll need it to complete the integration in the Paystand Dashboard.

Step 2: Enable an offline payment method

This step creates a visible “Paystand” payment option in your store

1. Go to Store Setup > Payments
   

2. Under Offline Payment Methods, enable Money Order
   

3. Change its display name to Paystand
   
   Note: You can also edit the Payment Information section to display a custom message after the order is completed.

4. Click Save

Step 3: Configure Paystand in your Dashboard

1. Log in to your Paystand Dashboard

2. Go to Integrations

3. Add the BigCommerce Webhook URL
   In the Webhook Event URLs module, ensure webhooks are enabled and add the following URL:

   https://bigcommerce.paystand.com/api/webhook/transactions

   

4. Go to Configure BigCommerce Settings
   

5. Enter the following details:

   • Publishable Key

   • Client Secret

   • Customer ID

   • Client ID

   • (Optional) Checkout Preset Key

   

6. Add the BigCommerce API credentials from the file downloaded in Step 2
   

7. Click Verify Connection

8. When the Save Configuration button becomes active, click Save Configuration

9. Finally, go back 

Result

• Your BigCommerce store is now securely connected to the Paystand payment network

Part 2: Install the Paystand Custom Checkout

Once your accounts are connected, you’ll upload the Paystand checkout files and enable the custom checkout

Step 1. Connect to your store via WebDAV

1. In your BigCommerce Admin Panel, go to Advanced Settings > File Access (WebDAV)
   

2. Click Download WebDAV Connection File — this file preconfigures Cyberduck or another WebDAV client with your store’s access details
   

3. Open Cyberduck and import the connection file
   
   Note: The simplest way to import your connection is to drag and drop the files directly into Cyberduck. You can also drag and drop multiple files at once.
    

4. When prompted, enter your WebDAV username and password (available in your Admin Panel)

Tips

• Use Cyberduck as your WebDAV client for best compatibility.

Step 2. Upload Paystand checkout files

1. Once connected, navigate to /dav/content/checkout
   

2. Upload the Paystand-provided checkout files into this directory
   

3. Confirm the files appear alongside your existing checkout scripts (for example, adyen-v2-payment-method.js, apple-pay-button.js)

Example file: auto-loader.js

Important

• Do not overwrite or delete existing checkout scripts when uploading Paystand files.
• Ensure that auto-loader.js is added as a new file inside the /dav/content/checkout directory.
• Always confirm that your store’s original payment scripts (such as card processors or wallets) remain intact to avoid checkout disruption.

Step 3. Enable the custom checkout

1. In your BigCommerce Admin Panel, go to Advanced Settings > Checkout
   

2. Change your Checkout Type to Custom Checkout
   

3. Scroll to the Custom Checkout section

4. In the Script URL field, enter:

5. webdav:checkout/auto-loader.js

   

6. Click Save

Step 4. Verify the installation

1. Open your storefront in a browser

2. Add a product to your cart and proceed to checkout

3. You should now see the Paystand custom checkout experience

4. Complete a test order to confirm functionality

Step 5. Troubleshooting

If you don’t see the custom checkout:

• Confirm that the correct loader file (auto-loader.js) was uploaded

• Clear your store’s cache or CDN to ensure the latest files load

• If issues persist, contact Paystand Support with your store name, screenshots, and any console error logs
