I'm working on an app where users add a card before making a payment. However, I noticed that even when using a dummy card, it successfully generates a token in live mode, which is unexpected.
I want to implement a validation step to check if the card is valid and has sufficient balance before proceeding with the payment. Ideally, this should help prevent unnecessary transactions or failed payments due to insufficient funds.
Has anyone faced a similar issue? Is there a recommended API or method to verify card validity and balance before attempting a transaction?
Any insights or best practices would be greatly appreciated! Thanks in advance.
