### 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

| Area | Permission |
| --- | --- |
| Content | Read-only |
| Checkout Content | None |
| Customers | Modify |
| Customers Login | None |
| Information & Settings | Modify |
| Marketing | None |
| Orders | Modify |

**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:

```plaintext
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. ```auto
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
