[WEB - SDK] - Add Payment Method with Dynamic Field Rendering - BACS Bank Transfer

sakksham7 commented 1 month ago

The Hyperswitch SDK is a versatile tool built to streamline payment integration for developers. It simplifies the process of adding multiple payment methods, allowing you to quickly implement support for various gateways without the need to manually integrate each one. With Hyperswitch, you can efficiently manage payments across platforms, reducing complexity and boosting development speed.

Getting started

Get familiar with ReScript.
Check the README.md for project structure and setup instructions.
To setup locally, follow these steps

#  Clone repository
cd hyperswitch-web
yarn install
yarn run server     # This starts the mock server
yarn run re:start   # In another terminal

# Start Demo App in another terminal
cd hyperswitch-react-demo-app
yarn install
yarn run start        # This starts the demo app

Description:

We are looking to implement a new payment method in our WebSDK that supports dynamic field rendering. The goal is to allow the backend to define the fields required for the payment method and have the frontend WebSDK render these fields dynamically based on the response.

This feature should be flexible enough to handle different payment methods, each potentially requiring different types of input fields (e.g., text fields, dropdowns, checkboxes, etc.).

Requirements:

Payment Method Integration Details:

In this section, we provide details on the payment call response and the confirm call payload for the newly integrated payment method. Ensure you have configured the payment method at Hyperswitch Dashboard correctly. The backend already includes support for this payment method, so no additional configuration is needed.

Confirm call Payload should look like:

Dynamic Field Rendering:

Based on the backend response, the WebSDK should dynamically generate the necessary input fields.
Each field should be properly validated (e.g., required, length, pattern matching) based on the backend specifications.
Support different types of fields such as:
- Text fields (e.g., for name, card number)
- Select dropdowns (e.g., for country or card type)
- Checkbox fields (e.g., for terms and conditions)

User Inputs:

Once the user fills in the fields, the WebSDK should package the input data and send it back to the backend for payment processing.

Contribution Guidelines:

Fork the repository and create a new branch for your work.
Ensure the WebSDK follows best practices for API integration and field rendering.
Write clean, well-documented code with clear commit messages.
Add unit tests to ensure the dynamic field rendering works as expected.
Make sure to follow our coding standards and contribution guidelines.
