Step 1: Purchase and Download the Plugin

  1. Visit the official Indatos product page: Authorize.Net WooCommerce Plugin 
  2. Complete the purchase for the appropriate license.
  3. Log in to your Indatos account and download the plugin ZIP file.

The downloaded ZIP file contains the full plugin package required for installation.

Step 2: Install the Plugin in WordPress

  1. Log in to your WordPress admin dashboard.
  2. Navigate to Plugins > Add New.
  3. Click Upload Plugin.
  4. Select the downloaded plugin ZIP file and click Install Now.
  5. Once installation completes, click Activate.

After activation, the payment gateway becomes available in WooCommerce settings.

Step 3: Retrieve Authorize.Net API Credentials

To authenticate your store with Authorize.Net, you must obtain API credentials from your merchant account.

  1. Log in to your Authorize.Net merchant dashboard.
  2. Navigate to the API credentials section.
  3. Copy your API Login ID.
  4. Generate or retrieve your Transaction Key.

Keep these credentials secure.
They are required to process payments and should never be shared publicly.

Step 4: Configure the Plugin in WooCommerce

  3. Click Manage.
  4. Enter your API Login ID and Transaction Key.

Step 5: Enable Payment Methods

Within the plugin settings, enable the payment options you wish to offer:

  • Credit card payments
  • Debit card payments
  • eCheck payments, if supported by your merchant account

Ensure the payment method is visible on the checkout page before proceeding.

Step 6: Test Transactions

Testing is critical before accepting live payments.

  • Enable test mode or use Authorize.Net sandbox credentials.
  • Place a test order using test card details.
  • Confirm the order appears in WooCommerce with the correct status.
  • Test refunds and voids directly from the WooCommerce order screen.

Successful testing confirms that payments, order creation, and transaction handling are working correctly.

Step 7: Switch to Live Mode

  1. Disable test mode.
  2. Enter live production API credentials if not already configured.
  3. Place a real transaction with a valid payment method.
