(1 review)


PISP (Payment Initiation Service Provider API): PISP APIs are payment initiation services that offer retailers another way of taking online payments. These service providers let a shopper pay directly from his/her bank account. Users do not give a bank login details to a merchant, or, vice versa, the merchant user’s login details to the bank account; users simply give permission to the merchant to execute payments on the user’s behalf via the bank account.
