Implementing Sofort and EPS payment methods with Airwallex

[sudhirrnanda]

Update on AirWallex Problem Statements

AirWallex mandates the use of an organization email for Sandbox account setup. As a result, we'd like to ask candidates to select alternative problem statements. We will be adding more problem statements soon.

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.

Airwallex is a financial technology company that provides businesses with global payment solutions, including cross-border payments, foreign exchange, and risk management, with easy integration. In Hyperswitch parlance, Airwallex is one of the connectors we have integrated with. As of now, hyperswitch supports card payments and google pay wallet payments through Airwallex

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

Problem Statement

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

• Sofort is popular in Germany, Austria and Switzerland and quickly gaining popularity all over the EU

• EPS, while originally developed by Austrian Banks, is also a very popular payment method in the EU

The goal is to extend hyperswitch’s integration with Airwallex needs to support Sofort and EPS

How to get started:

1. Set up a Rust environment and run Hyperswitch locally

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

How to Implement:

Now you can get started with the 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 Airwallex, 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 Airwallex to implement Sofort and EPS through Airwallex

6. Implement Sofort and EPS using the API references in point 4. Modify the following file to implement Sofort and EPS

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

Note: We welcome multiple PRs for this problem statement

Hi @c10n3, I wanted to work on the same problem. Is it first come, first served, or can multiple people work on the same problem? Please clarify. Thanks!

[manojradhakrishnan]

Multiple developers can attempt the same problem. We value approach and clean code more than anything else.

[manav-chan]

I am done with setting up the Rust development environment for Hyperswitch and tried the basic APIs, and now I am researching on this issue..

[manojradhakrishnan]

Good luck. Please try creating a pull request for the feature.

Hi @manojradhakrishnan just a heads up - discussion #4145 mentions Sofort and EPS, along with SEPA and BACS in point 6

Implement SEPA and BACS using the API references in point 5. Modify the following file to implement Sofort and EPS

I covered both in my PR, let me know if I should include this discussion thread in PR description as well.

[neerajkumar-n]

@CuriousCorrelation - I see your PR, but i don't think you have filled in the google form. Why don't you fill the google form: https://forms.gle/QQfA5fdG37QvCDio8

[manojradhakrishnan]

Thanks for letting know. Fixed the description.

[CuriousCorrelation]

@neerajkumar-n Thanks you so much for the remainder! Just waiting to hear back from a couple of recent collaborations to make sure everything is up to date.

A quick question if you don't mind, it seems the form expects one challenge, tho will it be alright to include all #4179 at #4191, #4144 + #4145 at #4222, perhaps comma separated? I believe they might offer insight in both planning and execution, if it wouldn't be too much trouble of course.

[neerajkumar-n]

Yes @CuriousCorrelation, please do add them with a comma separated.

[CuriousCorrelation]

Hey @neerajkumar-n thanks for your patience, form's filled and sent! Email is same as my username here if you'd like to confirm. Thanks again for the remainder.
