Square is a leading FinTech company that provides a comprehensive payment gateway solution for businesses of all sizes. It enables merchants to accept payments via credit and debit cards, manage transactions, and streamline their checkout processes. Square's APIs are widely used in production applications to facilitate seamless payment processing.
When integrating Square's payment gateway, developers may encounter the INVALID_EXPIRATION_DATE error. This error typically arises during the payment processing stage and indicates that the expiration date provided for a credit or debit card is not valid.
The most common symptom of this issue is a failed transaction attempt, accompanied by an error message stating "INVALID_EXPIRATION_DATE". This error prevents the transaction from being completed successfully.
The root cause of the INVALID_EXPIRATION_DATE error is usually an incorrectly entered expiration date. This could be due to a typo, an expired card, or a format mismatch. Ensuring the accuracy of the expiration date is crucial for successful payment processing.
To resolve this error, follow these actionable steps:
Ensure that the expiration date is entered in the correct format. Square typically requires the date in MM/YY format. Double-check the input field and adjust the format if necessary.
Review the expiration date for any typos. A simple mistake in the month or year can lead to this error. Correct any errors and attempt the transaction again.
Ensure that the card being used is not expired. If the card has expired, request an updated card from the customer and retry the transaction.
Incorporate validation logic in your application to check the expiration date before submitting the transaction. This can prevent invalid dates from being processed. For more details on implementing validation, refer to Square's developer documentation.
