Payment Method SDK

The Payment method SDK allows you to securely collect payment information and give customers the option to save their payment details for future transactions. By vaulting these details during the inital checkout phase.

Key Features

• Full Token Management – Create, retrieve, update, and delete payment tokens directly from your server.

• PSP and Network Tokenization – Generate both PSP tokens and network tokens through a single API.

• Secure Storage – Store tokens safely in Hyperswitch’s Vault.

• Reduced Frontend Complexity – Shift tokenization processes to the backend, minimizing frontend dependencies.

Understanding Payment and Vault Flow

Vaulting :

1. Collect Card Details – Your server collects card details (requires PCI compliance).

2. Send a Tokenization Request – Make a POST request to /payment_methods with the card details.

3. Token Creation & Validation – Hyperswitch validates the request and generates a secure token in the vault.

4. PSP & Network Tokenization (Optional) – If configured through your Hyperswitch dashboard, we also generate PSP and/or network tokens when you pass relevant parameters as mentioned below

5. Receive Payment Method ID – You get a pm_id, which can be used for future payments.

6. Payment using stored card : For payment you will will have to call the /payment/create API and pass the value of parameter confirm as true.
