Hi there, you are looking for Card External Accounts specifically here?

For Custom Connected Accounts, I assume?

[meager gulch]

yep

so this field of the requirements

[nimble tinsel]

Gotcha

Yep you can use our Card Element

To create a Token

And then pass that to your Server to create an External Account

[meager gulch]

and the card element checks the validity doesnt it

[meager gulch]

thats really helpful actually, thank you

[nimble tinsel]

The Card Element will ensure that it is a legitimate credit card number (it uses the Luhn check), but it won't validate the card with the issuer. That would happen when you create the External Account server-side.

[meager gulch]

okay gotcha. so instead of adding the external account ON account creation

I do it afterwards like so

(tok_mastercard would be what I get from the CardElement)

and that api would return/throw an error if the card isn't valid

correct?

[nimble tinsel]

Yep exactly

Recommend testing it out!

[meager gulch]

yep

thank you all clear
