Overview

WSO2 released version 3.1 of its open source API Manager platform in April 2020, targeting three broad themes: expanded support for modern deployment architectures (Kubernetes, microservices, and serverless), stronger API security, and an improved developer experience. The release ships under the Apache License 2.0 and is backed by the WSO2 Subscription service.

WSO2 API Manager is positioned as a full-lifecycle API management platform covering API creation, publishing, consumption, and monitoring. Version 3.1 ships alongside a matching release of WSO2 API Microgateway, its cloud-native, decentralized gateway component aimed at microservices deployments.

WSO2 API Microgateway 3.1

The Microgateway is a lightweight, developer-centric API gateway designed for decentralized deployments alongside microservices. It integrates with WSO2 API Manager for centralized management while running independently at the edge — in Kubernetes clusters, containerized environments, service meshes, and hybrid deployments. WSO2 states it can boot in under one second.

Key additions in version 3.1 include:

• gRPC support: The Microgateway can now expose managed gRPC endpoints, making it suitable for microservices and mobile backends that use the gRPC remote procedure call protocol.
• Runtime language choice: Developers can select either Java or Ballerina (WSO2’s open source networking-oriented language) as the runtime for the Microgateway.
• Improved observability: Enhanced message tracing capabilities give operators better visibility into traffic flowing through the gateway.
• Strengthened authentication: New options include API key-based authentication, combined authentication schemas, and support for multiple JWT issuers.

Extended Support for Kubernetes, Containers, and Serverless

Kubernetes API Operator

WSO2 introduced native Kubernetes support via a Kubernetes API Operator in 2019 — treating API management configuration as a first-class Kubernetes resource. Version 3.1 extends that operator with:

• Support for multiple Docker registries: Docker Hub, Amazon ECR, Google Container Registry, Quay.io, and generic HTTP/HTTPS registries.
• The ability to expose multiple Swagger/OpenAPI definitions as a single API.
• Automatic microgateway deployment from a Swagger definition — intended to reduce time-to-deployment for microservices to minutes.
• Deployment and management of KNative (serverless) applications.
• API management applied to microservices running inside an Istio service mesh.
• Java interceptors for mediation logic when exposing APIs.
• API exposure via a Kubernetes Ingress controller to provide a single ingress point for API traffic.

AWS Lambda Integration

WSO2 API Manager 3.1 adds native AWS Lambda integration, allowing developers to front Lambda functions with managed API endpoints. The integration supports two credential models for invoking Lambda functions:

• Stored AWS credentials configured in the API Manager.
• Temporary credentials supplied by an AWS IAM role.

This makes it straightforward to apply API management policies — rate limiting, security, analytics — to serverless backends without changing the Lambda function itself.

Expanded API Security

API Security Audit Integration with 42Crunch

WSO2 partnered with 42Crunch to develop an open source extension that integrates the 42Crunch API Security Audit tool directly into WSO2 API Manager. The integration scores an API’s OpenAPI/Swagger definition across three dimensions:

• OpenAPI format compliance
• Security posture
• Data validation coverage

The audit report identifies specific lines in the API definition where issues exist, explains how each vulnerability could be exploited, and links to remediation guidance. Developers can edit the API definition using the built-in Swagger Editor inside WSO2 API Manager and immediately re-run the audit to verify the fix.

Enhanced JWT Authentication

WSO2 API Manager has supported JSON Web Tokens (JWT) for OAuth 2.0-secured APIs since an earlier release. Version 3.1 adds three enhancements:

• Backend JWT separation: The backend JWT is decoupled from the client JWT, preventing user information from being forwarded to backend services without explicit consent.
• User claims in backend JWTs: Developers can embed user claims into the JWT passed to the backend service, enabling user-context-aware logic inside the API implementation.
• Multiple JWT issuers: The API gateway can now validate tokens issued by multiple identity providers, allowing organizations to bring their own JWTs from external systems.

These enhancements are particularly relevant for hybrid and distributed API gateway deployments, where reducing round-trips to a central token validation service improves both scalability and operational cost.

Improved Developer Experience

AI-Powered API Recommendations

The API Store (developer portal) in WSO2 API Manager 3.1 gains an AI-powered recommendation engine. Rather than relying solely on keyword search, the system analyses developer behaviour and the application under development to surface APIs that are likely to be relevant — reducing discovery time for developers exploring a large API catalogue.

API Categories

API providers can assign a category to each API from a predefined list managed by the portal administrator. The developer portal then groups APIs by category, providing an alternative to tag-based browsing. Providers no longer need to follow tag naming conventions — they simply select the appropriate category. If no suitable category exists, providers can request that the administrator create one.

API Mocking

Building on the existing API prototyping feature, API mocking in version 3.1 allows developers to define mock response payloads for each response code and content type directly in the API definition. The inline script for payload generation is generated automatically from example values or response schemas in the OpenAPI definition. This lets API testers interact with a realistic simulated API before the actual backend is ready — without requiring a subscription.

Availability and Licensing

WSO2 API Manager 3.1 and WSO2 API Microgateway 3.1 are available as open source software under the Apache License 2.0. Enterprise support is available through WSO2 Subscription, which includes:

• WSO2 Update — continuous delivery of bug fixes, security patches, and performance improvements.
• WSO2 Support — 24×7 technical support.
• Flexible hosting: cloud, on-premises, or hybrid, under unified pricing.

About WSO2

Founded in 2005 and headquartered in Mountain View, CA, WSO2 provides an open source, API-first integration platform. At the time of this release, the company employed over 600 staff across offices in Australia, Brazil, Germany, Sri Lanka, the UK, and the US, and reported that its integration technologies processed over 6 trillion transactions annually for enterprise customers worldwide.

From Brick-and-Mortar to Brazil’s Digital Powerhouse

Dubbed “the Amazon of Brazil,” retailer Magazine Luiza — universally known as Magalu — has become one of the most widely studied digital transformation success stories in retail. Between January 2015 and mid-2019, the company’s stock price reportedly increased more than 18,000% in value. That figure is striking on its own, but it becomes extraordinary when you consider that Brazil was simultaneously enduring its worst recession in modern history when the rally began.

Less than a decade earlier, few would have predicted such an outcome. Magazine Luiza was a predominantly brick-and-mortar operation struggling with economic instability and rising pressure from digitally-native competitors. What changed? And what can enterprise leaders learn from how Magalu engineered its transformation? Here are five actionable lessons.

Lesson 1: Change Must Come From the Top

Magalu CEO Frederico Trajano did not frame digital transformation as a series of app launches or isolated technology projects. His vision was comprehensive: move technology from a back-office support function to the strategic core of the business.

“Technology [must move] from the background to center stage — and [be] seen as the brain of the business. Hierarchical structures, paralyzed by excessive bureaucracy, the fear of change and attachment to past successes, usually strongly reject the digital culture.”

— Frederico Trajano, Magalu Q4 2016 Earnings Statement

This top-down commitment matters because digital transformation is as much a cultural and organizational challenge as it is a technical one. Without clear executive sponsorship, the typical enterprise stalls: individual teams digitize existing processes without rethinking them, silos persist, and KPIs never evolve to reward new behaviors. Meaningful transformation requires leadership that is willing to:

• Redefine incentives and performance metrics to reinforce digital-first behaviors
• Break down organizational silos that block cross-functional collaboration
• Invest in retraining and reassuring employees who fear displacement
• Communicate a clear vision that connects technology investment to business strategy

Without that mandate from the C-suite, even well-funded technology programs tend to produce incremental efficiency gains rather than genuine business model change.

Lesson 2: Innovators Need Room to Innovate

Trajano recognized early that transforming a large organization requires a dedicated engine for innovation. In 2012, he established Luizalabs — an internal technology and innovation team that started with a small group of developers and eventually grew to more than 900 employees spread across four buildings in two Brazilian states.

Two deliberate decisions made Luizalabs effective rather than merely symbolic:

1. Access to core systems. Developers were given direct access to Magalu’s live business systems, rather than being isolated in a sandbox working on theoretical prototypes with no path to production.
2. Freedom from heavy governance. Luizalabs was exempted from the company’s slower, bureaucratic approval processes, allowing it to operate with startup-like velocity.

“The idea was to try to break the entire system — to show that it’s possible to have IT close to the business guys. Before, there were very heavy processes. It would take two months to get all the information.”

— Andre Fatala, CTO and head of Luizalabs

By adopting agile development practices, automated testing, and lighter-touch governance tooling, Luizalabs compressed delivery cycles from months or years down to weeks or days — and created a repeatable blueprint the broader organization could learn from and scale.

Lesson 3: IT Agility Is a Precondition for Business Agility

Speeding up software delivery requires more than a motivated team — it requires an architecture that supports rapid, independent change. Magalu’s legacy systems were largely monolithic: large, tightly coupled codebases where changing one component risked breaking others, and where multiple developers could rarely work in parallel without stepping on each other.

Migrating everything at once was not practical, so Magalu adopted a two-speed IT strategy:

• Front-end acceleration: Customer-facing applications were decoupled from back-end systems using APIs, allowing front-end teams to iterate quickly on user experiences without waiting for back-end changes.
• Back-end modernization at its own pace: Core systems of record were maintained and gradually re-architected without blocking customer-facing development.

“In 2013 we had an e-commerce platform, and even a library of APIs, but those APIs were accessing an overstretched backend application built with 150,000 lines of code. Deployment of new APIs was slow, we were burdened with undesirable dependencies, and we faced scalability challenges as well as distributed responsibilities across siloed teams.”

— Andre Fatala, CTO, quoted in a Google Cloud blog post

Over time, this two-speed approach evolved into a full microservices architecture — where applications are composed of small, independently deployable services rather than built as monolithic blocks. Each service is exposed via a well-defined API, making it discoverable and reusable by other teams. API management tooling gave Magalu visibility into how its business capabilities were being consumed, enforced access controls, and generated usage analytics across the platform.

The practical result: developers could combine existing services like building blocks to ship new products without rebuilding functionality from scratch each time.

Lesson 4: Digital Platforms Unlock New Business Models

With a modular, API-driven architecture in place, Magalu could pursue business strategies that would have been impossible on its legacy systems. In 2016, the company launched a third-party digital marketplace, allowing external sellers to list products under the Magalu brand.

The impact was immediate and measurable:

• The legacy integrated system had supported fewer than 50,000 SKUs.
• The marketplace eclipsed 1 million SKUs by late 2017.
• It eventually grew to include more than 8,000 sellers offering 7.5 million SKUs.

Because the marketplace is API-driven, onboarding new merchants adds virtually no marginal infrastructure cost. Automated monitoring and rule enforcement keep the seller ecosystem healthy without requiring proportional increases in headcount.

Magalu also introduced Lu, an AI-powered virtual influencer designed to help shoppers discover products — an early signal of where the company’s ambitions were heading. By 2018, Trajano was describing a much broader vision:

“We are not only building an app, but rather a ‘superapp’: a digital environment where customers can go shopping, pay bills, top-up their mobile phones, hire transportation services, buy lunch. By attracting partners to the superapp environment we will increase our chances of attracting new customers, whose interactions with the company will be even more frequent and meaningful.”

— Frederico Trajano, Magalu Q4 2018 Earnings Statement

The platform mindset — building infrastructure that others can build on — is what separates companies that digitize existing processes from those that create entirely new categories of value.

Lesson 5: True Transformation Reaches Every Corner of the Business

Customer-facing digital experiences are a critical piece of transformation — but they are not sufficient on their own. Magalu recognized that a slick e-commerce front end would disappoint customers if the operational reality behind it could not deliver. Transformation had to run deeper.

Specific operational changes included:

• In-store employee tools: Sales associates were equipped with apps that surfaced local inventory data, enabled card payments anywhere on the shop floor, and guided customers through digital credit verification — eliminating friction at the point of sale.
• Last-mile delivery: Thousands of contract drivers use a Magalu app in a rideshare-style model to fulfill online orders, compressing delivery windows and reducing dependence on traditional logistics providers.
• In-store pickup: Technology was applied to make click-and-collect experiences simpler and more reliable, bridging online and physical retail.

The lesson here is straightforward: a great digital storefront backed by a slow, manual operation will erode customer trust. Sustainable digital transformation requires that the entire value chain — operations, logistics, employee tooling, and finance — evolves alongside the customer experience.

Final Thoughts: Technology Is a Road to Change, Not Change Itself

Magalu’s story is not a story about any single technology. It is a story about using technology deliberately and consistently to serve customers better, empower employees, and open new business models. Enterprises that frame digital transformation around specific technologies — a cloud migration, a machine learning initiative, a mobile app — risk achieving incremental efficiency improvements while leaving the fundamental structure of their business unchanged.

The five lessons from Magalu point to a different approach:

1. Secure genuine executive commitment — not just sponsorship, but active vision-setting and cultural leadership.
2. Create protected space for innovation, with real access to real systems and freedom from bureaucratic drag.
3. Modernize your IT architecture so that business agility is technically possible, not just aspirationally desired.
4. Think in platforms and ecosystems, not just products and features.
5. Extend transformation through the entire operating model, not just the customer interface.

Technology is a means to an end. The end is a business that can change as fast as its customers’ expectations do.

WSO2 API Microgateway 3.0: What Changed

At OSCON, WSO2 announced version 3.0 of its open source WSO2 API Microgateway, a lightweight, developer-focused API gateway designed for microservices architectures. The release introduced several capabilities aimed at reducing the operational burden of managing large numbers of APIs across distributed systems.

Key Features Introduced in Version 3.0

• Multi-microservice API exposure: Multiple microservices can now be exposed through a single API endpoint, simplifying the interface surface for consumers.
• Automatic microservice discovery: The gateway can detect microservices automatically, reducing manual configuration overhead.
• Legacy API transformation: Incoming legacy API request formats can be translated into more modern formats, easing migration paths.
• OpenAPI Specification (OAS) support: Previously known as Swagger, OAS support was added to improve developer collaboration on API design and documentation.
• Decoupled toolkit and runtime: The WSO2 API Microgateway toolkit was separated from its runtime, enabling greater scalability and allowing smoother, less disruptive upgrades.

Performance and Core Capabilities

The WSO2 API Microgateway is engineered for fast startup — designed to boot in under one second — making it well-suited for dynamic, container-based environments where services are frequently started and stopped. Beyond routing, it provides a broad set of built-in capabilities out of the box:

• Authentication and authorization
• Rate limiting and throttling
• Service composition
• Service discovery
• Request and response transformation
• Analytics and observability

It is designed to integrate with the WSO2 API Manager, an open source API management platform that can be deployed on-premises or in the cloud, giving teams centralized visibility and control over their API estate.

Kubernetes and Container Orchestration Support

Recognizing that the majority of microservices are now deployed in containers, WSO2 built native Kubernetes support directly into the gateway. This allows teams to generate Kubernetes artifacts from the gateway configuration and apply them directly to Kubernetes clusters — tightly integrating API management into container orchestration workflows rather than treating it as an afterthought.

WSO2 also provides a visual flow diagram interface that lets organizations map and manage the relationships between APIs and services, offering a graphical overview of an otherwise complex dependency graph.

The Ballerina Connection: Integrating Development and Operations

A recurring theme in WSO2’s messaging around the Microgateway is the convergence of application development and integration work into a single team — a goal closely aligned with DevOps principles. To support this, WSO2 has actively promoted Ballerina, a general-purpose, open source programming language designed specifically for writing distributed integrations.

According to Ken Oestreich, vice president of product marketing at WSO2, Ballerina enables developers to build and embed their own micro-enterprise service bus (ESB) logic directly within a distributed application — without needing a separate, centrally managed integration layer. These integration components can then be version-controlled, tested, and deployed as part of standard CI/CD pipelines.

The Broader API Management Challenge in Microservices Environments

The WSO2 announcement addresses a problem that has grown significantly as container adoption has accelerated: API sprawl. In traditional monolithic architectures, managing a relatively small set of APIs was tractable. In a microservices environment, each discrete service exposes its own API, and the number of APIs in a large organization can reach into the thousands.

This creates several operational risks:

• Dependency fragility: APIs are often tightly interdependent. Changes to one API can degrade the performance of downstream consumers, even if no individual service crashes outright.
• Ownership ambiguity: Developers typically create APIs, but once those APIs are deployed to production, ownership often shifts to operations or platform teams — creating gaps in accountability.
• Operational visibility: Without centralized tooling, it becomes difficult to track which APIs exist, who is consuming them, and what the impact of a change or deprecation will be.

Integrating API Management into DevOps Workflows

The underlying challenge is cultural as much as technical: API management needs to become a natural, first-class part of the DevOps lifecycle rather than a separate concern handled by a siloed team. This means treating API definitions as code, versioning them alongside service code, and including API contract testing in CI/CD pipelines.

The WSO2 API Microgateway 3.0 release reflects an attempt to make this integration more practical — by decoupling the toolkit from the runtime, supporting OAS for design-time collaboration, and providing Kubernetes-native deployment artifacts that fit naturally into GitOps and pipeline-driven workflows.

For teams managing large numbers of microservices, a gateway that can boot in under a second, auto-discover services, and integrate directly with Kubernetes represents a meaningful improvement over heavier, centralized API gateway patterns inherited from SOA-era architectures.
