1. Understanding Authorize.net’s API Capabilities

Authorize.net provides APIs for handling transactions. When integrating the API, ensure that the decline codes are captured effectively. This allows you to trigger the pop-up window only when necessary.

2. Creating the Basic Pop-Up Framework

Use HTML and JavaScript to build a basic pop-up window.

<div id=”decline-popup” style=”display: none;”>

    <h2>Transaction Declined</h2>

    <p>Your transaction could not be processed. Please check your details and try again.</p>

    <button onclick=”closePopup()”>Close</button>

</div>

3. Styling the Pop-Up Window

To style your Authorize.net declined transaction pop-up window, use CSS:

#decline-popup {

    position: fixed;

    top: 50%;

    left: 50%;

    transform: translate(-50%, -50%);

    background-color: #f8d7da;

    color: #721c24;

    border: 1px solid #f5c6cb;

    padding: 20px;

    z-index: 1000;

    box-shadow: 0 4px 8px rgba(0, 0, 0, 0.2);

}

button {

    background-color: #721c24;

    color: white;

    border: none;

    padding: 10px 20px;

    cursor: pointer;

}

4. Integrating with Authorize.net’s Response Codes

When a transaction fails, Authorize.net provides a response code. Use JavaScript to display the pop-up based on the response code.

function handleTransactionResponse(responseCode) {

    if (responseCode === ‘DECLINED’) {

        document.getElementById(‘decline-popup’).style.display = ‘block’;

    }

}

function closePopup() {

    document.getElementById(‘decline-popup’).style.display = ‘none’;

}

5. Testing the Declined Transaction Pop-Up

Ensure the Authorize.net declined transaction pop-up window works across browsers and devices. Simulate declined transactions during testing to verify functionality and appearance.
