Stripe allows you to implement unique business logic so you can write fraud prevention rules specific to your business.
Block: Rules that block a payment and reject it. Blocked payments aren’t evaluated against any review rules.
Block
Block rules specify that Stripe should always block a payment. If a payment matches the criteria in a block rule, Stripe rejects it and it’s not subject to further rules evaluation.
Rule structure
The rule structure has two components—the action it should take and the condition to evaluate:
{action} if {condition}
For credit card block we use
Block if :card_funding: = ‘credit’
