Identifying the Symptom: Invalid Expiry Date

When integrating Adyen into your application, you might encounter the error message 'Invalid Expiry Date.' This error typically appears during the checkout process when a customer attempts to make a payment using a credit or debit card.

What You Observe

The transaction fails, and an error message is displayed, indicating that the expiry date provided is invalid. This can lead to a poor user experience and potentially lost sales.

Exploring the Issue: Why 'Invalid Expiry Date' Occurs

The 'Invalid Expiry Date' error occurs when the expiry date entered by the user is incorrect or has already passed. This can happen due to user input errors or outdated card information.

Common Causes

• The user mistyped the expiry date.
• The card has expired.
• The format of the expiry date is incorrect.

Steps to Fix the 'Invalid Expiry Date' Issue

To resolve this issue, follow these steps to ensure the expiry date is entered correctly and validated properly:

1. Validate User Input

Ensure that the expiry date field in your checkout form is properly validated. Use input masks or date pickers to guide users in entering the correct format (MM/YY).

2. Implement Client-Side Validation

Use JavaScript to perform client-side validation. Check that the expiry date is in the future and follows the correct format. Here's a simple example:

function validateExpiryDate(expiryDate) { const [month, year] = expiryDate.split('/'); const currentDate = new Date(); const expiry = new Date(`20${year}`, month - 1); return expiry > currentDate;}

3. Server-Side Validation

Always perform server-side validation to ensure data integrity. Verify that the expiry date is valid and has not passed before processing the payment.

4. User Feedback

Provide clear feedback to users if the expiry date is invalid. Display a message prompting them to check the date and try again.
