How We Helped Client Overcome Message Transaction Issues & Improved Business Processes With MuleSoft Integration

Legacy POS application needs to be synchronized with modern POS application

The client had a legacy POS application that was built on monolithic architecture and wanted to modernize its backend by moving to a new POS application. To prevent disruptions with the majority of the customers who were routed to the old POS system, they wanted to retain both POS applications. Along with the major challenges, there were time constraints for this transition.

• The client wanted to have a new POS application created using a similar API with some additional features.
• Integrate the systems and maintain both POS running until the process stabilizes.
• Planned to move to the new POS completely by eliminating the legacy POS system in the future.
• Create API for the E-com partners to integrate with their systems and enable a seamless transaction.
• Replace and upgrade the legacy authentication type with OAuth in the new POS application.
• The lower 3.x mule version extended support had matured and come to an end for the organization. The mule services had to be migrated from 3 .x version to the latest mule 4.x version.

A comprehensive enterprise integration solution to connect legacy & modern POS

We took a deep dive and comprehended the requirements clearly. Our team collaborated with the key stakeholders to understand their core business and identified the gaps for deriving feasible solutions.

Reusable APIs

Although the client was using MuleSoft's Anypoint platform for integrating the systems it required various modifications to deliver a connected experience to the customers and the trading partners.

To obtain this, our team developed numerous reusable APIs using the API-led connectivity approach. These APIs were then exposed as mule flows and all the business logic was performed in a very limited period.

We also developed E-com service APIs for the trading partners and exposed them to create a seamless integration opportunity with the respective applications.

Routing logic

Since the existing customers were routed to the old POS application, we developed Muleflows and performed routing logics to enable them to the right path.

For instance, if an existing customer initiated a request, it needed to be tracked and routed to the old POS application. Similarly, when a new customer shows up, this has to be routed to the new POS application.

Naming convention

To exclude and rule out any sort of commotion in the newly created APIs, we followed the best practices and exposed relevant APIs for the respective functionality. For instance: The Experience API for a hassle-free user experience; the process API for encapsulating business logic and operations; followed by the system API catering to the backend of the application.

Error logging and Unit testing

We achieved logging functionality with meaningful context and eased the troubleshooting task by setting the log levels for the integration. We leveraged MuleSoft's MUnit for building automated test cases and performed unit tests for the integration of APIs.

Deployment and support

We wanted to ensure quality and thus used the best DevOps practices for the development & testing of the APIs. To ensure reliability, we rendered our support using multiple deployment tools like Maven, Gitlab, and Jenkins for the release management. We extended our support by monitoring the deployments regularly and fixed the errors as and when required.

Version update/Migration

The client was using MuleSoft 3.x version and the extended support had already expired. However, all the services existing in the lower 3.x had to be migrated to the 4.x versions to continue using them and reap maximum benefits of the MuleSoft API management.

We rationalized the existing Mule 3 integration to enable a seamless migration. We then developed, optimized, and migrated all the services from MuleSoft 3.x to MuleSoft 4.x successfully without impacting the business logic within a short span of time. This led to seamless access to data, and detection of errors. It will also enable a frictionless upgrade in the future.

Authentication

When the migration to a new platform happens, review of the security implementation in the application and the infrastructure is of utmost importance. Further, the existing identity infrastructure used by the client in their legacy POS application was not modernized and thus was vulnerable at the endpoint. We recommended the best identity solutions for their new POS application and suggested OAuth for the authentications. We developed muleflows and configured them to generate the token using the actual API.

A scalable & future-proof integration strategy that drives business efficiency

With our team's industry-specific expertise, relentless support, and robust solutions, the client was able to

• Establish a scalable, consistent, and future-proof integration strategy.
• Reduce barriers and use both the legacy POS application & the new POS application.
• Streamline the process and increase productivity manifold.
• Achieve scalable and flexible POS systems with additional functions.
• Focus on the business process rather than the operations.
• Connect with the customers and the trading partners at a faster rate.
• Enriched security and ensured confidentiality across the integrations.
