3 digit security code fails with E00003 cardcode invalid error unless I added leading zero?

[aaw]

Hi!

New PHP integration here. I was testing with my company amex with no issues. But the testers got started and right away are running into this.....

E00003 - cardCode element is invalid - The value XXXXXX is invalid according to its datatype, The Pattern constraint failed.

So I was stumped by this error until one of the testers added a leading 0 to the 3 digit VISA code he was trying to test with and then it worked?

My values are sanitized before sending them over, so I know there are no extra characters being submitted, so is the solution adding a leading 0 if the security code is 3 digits? I'm assuming there is something else going wrong with what I'm sending, but I'm at a loss as to what it could be? Thanks in advance for any help!

Thanks for the reply. It turns out it was my fault. I had an input mask on the card code field that only allowed 4 numeric digits. What I didn't realize is that if you entered less than 4, it appended an extra dash at the end of the string.

It seems like you're encountering an error message (E00003) related to the cardCode element when integrating PHP with your payment processing system. This error indicates that the value provided for the card security code is considered invalid.

The error message you've described suggests that adding a leading zero to a 3-digit VISA code resolves the issue for some testers. This could be due to a data type or validation constraint in the payment processing system.

Here are some steps you can take to further diagnose and potentially fix the issue:

1. Check API Documentation: Review the API documentation for the payment processing system you are integrating with. Ensure that you are sending the card security code in the correct format as specified by their requirements. It's possible that the system expects a 4-digit code, and adding a leading zero makes it comply with that requirement.

2. Contact the Payment Gateway Provider: If you can't find a solution in the documentation, consider reaching out to the payment gateway provider's support team. They can provide specific guidance on how to format the card security code for successful transactions.

3. Validate Data: Even though you mentioned that you sanitize your data, double-check that the card security code is being processed correctly in your PHP integration. Ensure that no extra characters or formatting issues are introduced during the data transfer.

4. Test Different Card Types: To confirm whether this issue is specific to VISA cards or not, try testing with other card types such as MasterCard or American Express. This will help you determine if the problem is widespread or isolated.

5. Logs and Error Handling: Implement comprehensive error handling and logging in your PHP integration. This will help you capture and analyze any additional error details that might provide more insight into the issue.

6. Consider Future-Proofing: While adding a leading zero might be a workaround for now, consider whether this approach will remain valid in the long term. Payment systems and APIs can change, so it's essential to stay updated and adapt your integration accordingly.

Ultimately, the key is to ensure that the card security code is sent in the correct format according to the payment gateway's requirements. If in doubt, contact their support for specific guidance on how to format this data correctly.
