Hello, hope you're doing well!
To summarize the question, I am trying to use Radar to ban the use of credit cards in my embedded checkout flow
Is that possible/are there are other more efficient routes to do the same?

Hi, you could use Radar but you would also use: https://docs.stripe.com/payments/accept-a-payment-deferred integration. You collect the payment method details and look at the funding_type: https://docs.stripe.com/api/payment_methods/object?api-version=2025-05-28.basil#payment_method_object-card-funding to then recollect a new payment method before you create the charge if they used a credit card
wintry cloak
I see, and this is possible when using Stripe Checkout Embedded?
fluid gale
Not this integration directly, but you can also look at the funding type of the card, https://docs.stripe.com/api/cards/object#card_object-funding.
You would need to know this before you create the Checkout Session so you can have a UI that says 'pay with debit card' for instance and then create the CheckoutSession.
There is another way but it is not recommended. You could create a CheckoutSession in setup mode, then inspect the payment method details/ card funding type and create the CheckoutSession if it's not a credit card. Again, this is not recommended to do this but sharing with you as an option
I think Radar is the best approach as you're using Checkout Sessions
wintry cloak
Understood, how would Radar be used exactly in this scenario?
fluid gale
if you add a block rule with Radar, it it will block the payment when the funding type is credit
wintry cloak
And how can I integrate it with my Checkout? Could you share show guide/docs?
fluid gale
You write the rule, https://docs.stripe.com/radar/rules on your Dashboard and it will apply to all the transactions
If you have any additional questions about Radar, our support team will be able to better assist: https://support.stripe.com/contact
wintry cloak
Perfect, and this will be auto applied to my payments through checkout?
If so what happens then when somone tries to use a credit card?
fluid gale
We're developers so we do not have expertise on fees. I see https://stripe.com/gb/radar/pricing but you can confirm when with support.

By signing up, you agree to the Terms of Service and authorize Stripe to charge an additional $0.02 USD per screened transaction after your 30-day free trial ends. You can cancel anytime.
If I want to do it without this, is there a free method?
fluid gale
I do not think so for custom rules
