[DMP 2024]: PISP demo app for Mojaloop

[elnyry-sam-k]

Ticket Contents

Description

Mojaloop supports Payment Initiation Service Provider (PISP) or Third-party Payment Initiation (3PPI) use case and while this has been implemented based on a standard API and currently being worked on for further improvements (version 2.0), there’s a need for a good demonstration tool using an “app” like interface.

This will help in demonstrating the use case to adopters and interested entities to easily understand the use case and how it works in Mojaloop (the design, security features and general feature set / functionality).

In addition, integration tasks involved and updates to actual PISP services to bring the dependencies up to date and tests to work will also be involved so that these can be run together for the demos / integration.

Goals & Mid-Point Milestone

Goals

• Goal 1: Update PISP/3PP services to run locally or on demo environments and update dependencies with tests running. Understand requirements for the app and document (sequences & frames)
• Goal 2: Provide an initial interface for the app/web app and a high level demo with minimal backend integration
• Goal 3: Using a test/demo PISP server, showcase end-to-end demo of PISP use case for Mojaloop [Goals Achieved By Mid-point Milestone]
• Goal 4: Update PISP services to address any dependency upgrades and testing issues
• Goal 5: [Bonus Goal] Review changes needed to the PISP services for the PISP API 2.0 and document technical requirements

Setup/Installation

https://github.com/mojaloop/pisp-project

Expected Outcome

A functioning PISP demo using a demo (third-party payment initiation) app showing an end-to-end sequences and integration of services involved. The focus here is on the demo app and basic integration with the PISP services such as PISP adapter.

Weekly Goals

Week 1

• Undertake the Mojaloop's introductory course: 'MOJA 101: Mojaloop Introduction'
• Complete the Mojaloop's special course for understanding APIs at Mojaloop, 'MOJA 102: Mojaloop API'

Week 2

• understand the objective of Mojaloop. Which is whatever DFSP you belong to, wherever payment you want to sent. Mojaloop will solve the problem. By enabling the reliability.
• Go through the API specific detailed documentations and sequence diagrams (https://docs.mojaloop.io/api/thirdparty/)

Week 3

• Attend session on "What is Mojaloop?" led by Tullo Sir for better clarity on what we are working towards.
• Mojaloop 's API (most important and base of the PISP services)(https://www.youtube.com/watch?v=_Z7dKvw7a-c)

Week 4

• Run the Core test Harness (CTH), and Testing Toolkit locally and understand basics
• Make a minor contribution to the Ml-Core-Test-Harness, within
  the documentation as a kickstart to understanding the pull request checks.

Week 5

• Analyze third-party APIs, functionality and sequences (apis and sequence diagrams)
• Using the TTK backend for developing ui for PISP demonstration.

Week 6

• Come up with a proper implementation plan using Figma design for end-to-end PISP demonstration (blueprint) with detailed step demonstration (link)

Week 7

• Run PISP related services locally (to be checked when got services up 3/3)
• Bring following services up to date: Service-1 [Auth-Service] (https://github.com/mojaloop/auth-service)
• Bring following services up to date: Service-2 [thirdparty-svc] https://github.com/mojaloop/thirdparty-api-svc
• Bring following services up to date: Service-3 [thirdparty-sdk] (https://github.com/mojaloop/thirdparty-sdk)

Week 8

• Finalize Figma design with reviews
• Get started with the development of the implementation plan (blueprint to developed version) (once the improvements in the presented implementation plan have been made as per the suggestions by mentor).
• An initial demo screen on TTK using the finalized Figma design is produced for review.
