eCommerce businesses need a powerful architecture to ensure smooth operations and efficient website performance. And you can either go for monolithic or MACH architecture to develop the eCommerce store.
The choice of architecture depends on different factors, such as the complexity of the requirements, scalability needs, development team expertise, long-term goals, budget, performance optimization, integration requirements, and the ability to embrace new technologies.
This is a Monolith to MACH series of 4 informative articles, each explaining different components of the MACH architecture – Microservices-based, API-first, Cloud-native, and Headless architecture. Read on…
First, let’s understand the difference between monolithic and MACH architecture.
Monolithic Architecture
Monolithic architecture for eCommerce refers to a traditional approach where the entire eCommerce application is built as a single, unified system. All components, including the frontend, backend, and database, are tightly coupled and packaged together as a single deployable unit.
Pros
Cons
MACH Architecture
MACH architecture stands for Microservices, API-first, Cloud-native, and Headless. It offers a more modular and decoupled approach to eCommerce application development.

Now that we know the differences between the two architectures, let’s discuss what APIs are.
APIs play a crucial role in enabling communication and integration between the various components and services. Consider the example of a delivery executive who goes to the store or warehouse and brings you the order.
Here are the most popular APIs used in the MACH architecture.
1. Service APIs
Service APIs are the APIs exposed by individual microservices in the eCommerce system. Each microservice provides well-defined APIs that allow other services or components to interact with its specific functionality. Service APIs enable communication between different microservices, facilitating the modular and independent development, deployment, and scaling of services within the architecture.
2. Commerce APIs
Commerce APIs provide access to eCommerce-specific functionalities, such as product catalogs, pricing, inventory management, shopping carts, and checkout processes. These APIs allow external systems or frontend applications to retrieve or update eCommerce data and perform transactions. Commerce APIs enable integrations with third-party systems, such as payment gateways, shipping providers, or marketing tools.
3. Content APIs
Content APIs are used to manage and deliver content in the headless architecture. They allow frontend applications to retrieve content, such as product descriptions, images, blog posts, or marketing banners, from a content management system (CMS) or digital experience platform (DXP). Content APIs enable content personalization, localization, and delivery across various channels.
4. Integration APIs
Integration APIs help in communication and data exchange between the eCommerce system and external systems or services. They enable integration with third-party applications, such as customer relationship management (CRM) systems, enterprise resource planning (ERP) systems, analytics platforms, or marketing automation tools. Integration APIs enable data synchronization, event notifications, and seamless collaboration with external systems.
5. Third-Party APIs
In addition to the APIs within the MACH architecture, third-party APIs are often utilized to leverage external services or functionalities. These can include payment gateways, shipping carriers, social media platforms, geolocation services, or other specialized services that complement the eCommerce offering. Third-party APIs expand the capabilities of the eCommerce system and enable seamless integration with external services.
Besides these, there are two more approaches to implementing APIs – open and private APIs.
Open APIs, also known as public APIs, are designed to be accessible to external developers, partners, or third-party applications. They are made available to the public and can be used by anyone who registers for an API key or meets certain authentication requirements. Open APIs are typically documented, well-defined, and follow industry standards to ensure ease of use and interoperability. They enable developers to build applications, services, or integrations that interact with the exposed functionality of the API provider. Open APIs foster innovation, collaboration, and the creation of ecosystem-driven solutions.
Private APIs, also called internal APIs or partner APIs, are designed for specific use within an organization or restricted to a limited group of trusted partners. They are not publicly accessible and require authentication or authorization to access. Private APIs are often used for internal systems integration, enabling different applications or services within an organization to communicate and share data securely. They provide a controlled and secure way to expose functionality or data to selected stakeholders while maintaining privacy and security measures. Private APIs are not typically intended for external public use.
Your eCommerce model plays an integral part in guiding the choice of APIs and data orchestration strategies. The specific requirements and characteristics of each eCommerce model influence the selection of appropriate APIs and the way data is orchestrated within the system. Here’s how different eCommerce models can guide these choices:
In the commerce-first model, you have an eCommerce platform on the frontend for the user experience and checkout. The backend uses APIs for data orchestration with an ERP, PIM, OMS, or other system. This strategy utilizes highly-extensible SaaS technologies.
The experience-first approach, also known as the headless commerce model, decouples the presentation layer from the eCommerce platform and uses popular CMS like WordPress. API connectivity is crucial for proper data orchestration in decoupled systems. This model prioritizes attracting customers by delivering pleasant content experiences. Through this approach, you can use the API economy to make use of the best applications at the presentation layer to address the challenges unique to your business.
APIs have a significant influence on various aspects of an eCommerce tech stack, including flexibility, security, reusability, scalability, and extensibility. Here’s a breakdown of how APIs impact each of these factors:
With well-designed and documented APIs, businesses can easily connect their eCommerce platform with third-party services such as payment gateways, shipping providers, marketing tools, or social media platforms. This flexibility allows businesses to adopt best-of-breed solutions, leverage specialized services, and adapt to changing business needs without the need for extensive customization or redevelopment.
APIs play a crucial role in maintaining security in an eCommerce tech stack. APIs provide controlled access to data and functionality, allowing businesses to implement authentication, authorization, and encryption mechanisms to secure communication and protect sensitive customer and business information. By adhering to security best practices, such as using secure protocols (HTTPS), implementing API keys or tokens, and applying rate limiting, businesses can ensure secure interactions between their eCommerce platform and external systems.
By exposing well-defined APIs, different components or services within the tech stack can be designed to interact with each other in a modular and reusable manner. For example, an inventory management API can be reused by multiple modules or applications within the eCommerce platform, ensuring consistent and efficient inventory management across different processes. API-driven reusability reduces redundancy, promotes consistency, and simplifies maintenance and updates across the tech stack.
APIs enable horizontal or vertical scaling of individual components or services. With properly designed APIs, businesses can scale specific functionalities independently based on demand or resource requirements. For example, by scaling the order processing API separately from the product catalog API, businesses can handle increased order volume without affecting the availability or performance of other components. APIs allow businesses to distribute the load, balance resources, and scale different parts of the tech stack efficiently.
Businesses can offer integration points for developers or partners to extend the capabilities of the eCommerce platform with the help of APIs. These extensions can range from custom integrations with external systems, adding new features or building specialized modules to meet specific business requirements. APIs enable businesses to build an ecosystem of extensions, plugins, or integrations that enhance the functionality and adaptability of the eCommerce tech stack.
