🌊Payment flows

Understand the flow of a transaction through Hyperswitch

This chapter will cover the payment flows available with Hyperswitch. Please reach out to us to learn more about the payment flows supported!

Payments flow

There are multiple stages in a Payment flow depending on the payment methods that are involved. Considering an one-time payment method where there was no redirection involved, the following stages form the Payment flow:

a) Creating a Payment: When your customer wants to checkout, create a payment by hitting the payments/create endpoint. Fetch and store the payment_id and client_secret

b) Loading the SDK: After your customer checks out, load the Hyperswitch SDK by initiating it with the client_secret and publishable_key

c) SDK being rendered: After you initiate the SDK, the SDK makes several API calls involving the /sessions and /payment_methods endpoints to load relevant payment methods and any saved cards associated with the customer

d) Customer enters the payment method data: After the SDK is fully rendered, your customer would choose a payment method and enter the relevant information and click pay

e) Confirming the payment: After the customer clicks pay, the SDK calls the payments/confirm endpoint with the customer's payment method details and post response, it displays the payment status

Here's a more detailed version of the payment flow:

Use-cases supported by Hyperswitch

What are PaymentIntent and PaymentAttempt objects and how do they work in Hyperswitch?

Hyperswitch uses the PaymentIntent object to track the status of a payment initiated by you. Since, Hyperswitch enables retrying a single payment multiple times across different processors until a successful transaction, we track each of these payment attempts through separate PaymentAttempt objects.

While PaymentIntent and PaymentAttempt have their own state machines, the various states in PaymentAttempt are also constrained by their respective mapping to the PaymentIntent statuses.
