How to verify card details in paypal valut Api - paypal

I have used paypal vault API to store the credit card details.When Iam saving the card I gave wrong card details.So When Iam trying to make the payment It is throwing error.Iam using the sandbox environment
Is there any process to know whether a card is valid or not while saving the card details?

Currently PayPal does not validate credit card information that is being stored using the /v1/vault/credit-cards. The card will be validated against the processor when you try to charge the buyer using CARD ID. There is no alternate for validating the card.

PayPal REST SDK - how to validate credit card accounts

I was able to implement credit card payments on my website. Now my problem is how do I identify if the credit card account is fake or a fraud. What I am doing is I store the credit card info using the vault api then I get those stored accounts for the user to choose what card they will use to purchase my product. However, i can't find a way to add some more validation on how to check if the user is the real user of that credit card account. Right now I can enter any credit card number by just using a card number generator and it directly submits the payment. I can see in my sandbox merchant account that the payment was successful.
So is there a way for me to prevent this?
Thanks to those who could help.
Processing a zero value payment authorization request is the most common way to authenticate the card details are valid without actually taking payment.

Update my PayPal card via 3rd party app?

Is it possible to update my card details stored in my PayPal account via a 3rd party app with the use of an API? I came across the below documentation but wasn't too sure in which scenarios it could be used?
"Update a stored credit card
Operation
PATCH /v1/vault/credit-cards/
Use this call to modify a credit card."
Any thoughts?
There is no API's available for updating the credit card on your PayPal account.
But, using Adaptive Payments, you can just add a new Payment Card using AddPaymentCard API.
Although, you would need to apply for an application at apps.paypal.com
The vault is for REST API which is used to store(encrypt) the buyer's credit card information and could be used for future transactions.The Vault API provides a secure way to store customer credit cards. By storing cards with PayPal, you can avoid storing them on your servers.

Paypal Vault and IOS mobile SDK

Can we store or use the vault feature of paypal via the IOS Mobile SDK?
I know we have to use the REST API to verify the payment after it has been made - Can we also call the vault API to store the customers credit card so that the customer doesn't have to renter their credit card details again when using our app?
Thanks!
Dave from PayPal here.
Within the PayPal iOS SDK we do store the customer's credit card information (using the PayPal vault), so that your customer can in the future make another payment using your app without needing to re-enter that information.
For this storage to occur, when you create the PayPalPaymentViewController you must pass in a non-nil payerId string. If for a subsequent payment you provide the same payerId, then the previously stored credit card information will be retrieved.
