​​Some payment methods require your customer to take additional steps to complete the payment. The PaymentIntent object’s next_action parameter specifies the type of customer action. Some common actions that customers need to perform are: ​​Redirect to their bank’s online service to authenticate and approve the payment. Verify ownership of their account by providing a one-time code that you post to the Stripe API (for example, microdeposits). Push funds (for example, in the case for bank transfers) through their bank’s online service. Not all payment methods require additional customer actions. For example, card payments (excluding 3D Secure) require no additional authentication beyond collecting card details.
