Square INVALID_DISCOUNT_CODE error encountered during checkout.

The discount code provided is invalid or expired.

Understanding Square's Payment Gateway

Square is a leading FinTech company providing a comprehensive suite of tools for businesses to manage payments, both online and offline. Its payment gateway API allows developers to integrate secure and efficient payment processing into their applications, facilitating seamless transactions for users.

Identifying the INVALID_DISCOUNT_CODE Error

During the checkout process, users may encounter the INVALID_DISCOUNT_CODE error. This error typically manifests when a customer attempts to apply a discount code that is either invalid or has expired, preventing the discount from being applied to the transaction.

Common Symptoms

  • Discount not applied to the total amount.
  • Error message displayed to the user indicating an invalid code.
  • Transaction cannot be completed with the desired discount.

Exploring the INVALID_DISCOUNT_CODE Issue

The INVALID_DISCOUNT_CODE error is triggered when the discount code entered does not match any active codes in the system. This can occur due to several reasons, such as typographical errors, expired codes, or codes that have been deactivated.

Possible Root Causes

  • Typo in the discount code entered by the user.
  • The discount code has expired.
  • The discount code is not applicable to the current transaction.

Steps to Resolve the INVALID_DISCOUNT_CODE Error

To resolve this issue, follow these steps:

Step 1: Verify the Discount Code

Ensure that the discount code entered by the user is correct. Double-check for any typographical errors and confirm that the code is still active.

Step 2: Check Code Expiry

Access the Square Dashboard and navigate to the Discounts section. Verify the expiry date of the discount code to ensure it is still valid.

Step 3: Validate Code Applicability

Ensure that the discount code is applicable to the items in the cart. Some codes may have restrictions on product categories or minimum purchase amounts.

Step 4: Update or Reactivate the Code

If the code has expired or been deactivated, consider creating a new code or reactivating the existing one. This can be done through the Square Dashboard by following the Square Developer Documentation.

Conclusion

By following these steps, you can effectively troubleshoot and resolve the INVALID_DISCOUNT_CODE error in your Square-integrated application. Ensuring that discount codes are valid and applicable will enhance the checkout experience for your users.
