[sudhirrnanda]

Context

Embracing diversity in payments is one of the core tenets of Hyperswitch. And we look forward to integrating a large variety of payment processors (connectors) and payment flows around the world.

Multisafepay is a Dutch fintech company that provides a range of payment solutions and services, including online payment processing, digital wallets, and fraud prevention tools, to businesses throughout Europe. In Hyperswitch parlance, Multisafe is one of the connectors we have integrated with. As of now, hyperswitch supports card payments, apple pay and paypal wallets and klarna (BNPL option) via multisafe

We look forward to including some more critical payment methods through Multisafe

Problem Statement

iDeal and Giropay are online banking based payment methods that allow end users to complete payments in their own banking environment.

• iDEAL has an almost 100% reach for Dutch businesses and processes close to 1 Billion transactions annually.
• Giropay is a major player in the German market, and supports about 32,000 online businesses.

The goal is to extend Hyperswitch’s integration with Multisafe to support iDeal and Giropay.

How to get started:

1. Set up a Rust environment and run Hyperswitch locally

2. Signup and create a sandbox account on Multisafe to get the API Credentials

How to Implement:

Now you can get started with implementation:

1. Read and understand the general guidelines on contributing to Hyperswitch

2. Import postman collection of hyperswitch from here

3. Understand the implementation of all different payment flows and how to add a connector

4. As mentioned earlier for Multisafe, card payments are implemented. Test out this flow from postman using these test resources and understand the API implementation

5. Study the relevant API Documentation of Multisafe to implement iDeal and Giropay through Multisafe

6. Implement iDeal and Giropay using the API references in point 5. Modify the following file to implement iDeal and Giropay

crates/router/src/connector/multisafepay/transformers.rs
crates/router/src/connector/multisafepay.rs

7. Test the following flows - Payment, Capture, Void and Refund using postman for your local implementation and generate relevant screenshots of the test cases.

Expected Outcomes:

Submit a pull request to the juspay/hyperswitch repository including the relevant screenshots of the test cases.

Brownie Points: Providing clear and comprehensive documentation and code comments.

Proposal: Implementing iDEAL and Giropay payment methods with Multisafe #4143

Objective

Add iDEAL and Giropay payment processors in Multisafepay connector.

Background

Currently multisafepay provides various payment processors from Banking Methods, BNPL, Credit and Debit cards, Prepaid cards and Wallets segment. From these hyperswitch's multisafepay connector provides support for credit cards and debit cards, mendate payements, GooglePay, Paypal and Klarna only. iDEAL and Giropay are from "Banking Methods" category.

iDeal

iDeal has direct and re-directed flow which is showed below:

direct: given iDEAL issuer code user customer will be directly redirected to the bank’s
page
redirect: Redirect customer to payment’s page to select their bank.

Giropay

giropay has only redirect flow which is exactly same flow as iDEAL’s redirect flow.

Approach

For iDeal deciding direct or re-direct payment type:
If bank name is provided in PaymentMethodData then direct path should be used otherwise redirect. If direct flow is selected then in MultisafepayPaymentsRequest ’s gateway_info must have issuer_id field.

List of iDEAL issuers and respective code is given below (source)

Code	Description
0031	ABN AMRO
0761	ASN Bank
4371	bunq
1235	Handelsbanken
9927	Nationale Nederlanden
9926	N26
0721	ING
0801	Knab
0021	Rabobank
0771	Regio Bank
1099	Revolut
0751	SNS Bank
0511	Triodos Bank
0161	Van Lanschot Bankiers
0806	Yoursafe
Only these banks should be allowed in PaymentMethodData for iDEAL.

Implementation

All the changes will be in connector/multisafepay.rs file and in the enums and traits for request object

• Add Ideal and Giropay in Gateway enum
• changes in impl TryFrom<&CheckoutRouterData<&T>> for MultisafepayPaymentsRequest

  • for payment_type : add pattern for redirect “giropay” and “iDeal” and direct “iDeal” payments

  • for gateway : add BankRedirectData::Ideal and BankRedirectData::Geropay pattern

  • for gateway_info: Only for direct “iDeal” payments,

    • issuer_id : get issuer id from the table above
      There are also optional gateway_info fields for modifying payment behaviours like allow_change_amount , min_amount and max_amount which are related to QR code payment in direct flop.
