Featured Case Study: Enterprise SAP & Zoho Integration

The Challenge: A major NZ B2B supplier needed to migrate to Zoho One while maintaining deep integration with backend SAP inventory management with zero room for downtime.

The Solution: Lumen designed a custom API architecture to bridge SAP with Zoho CRM, Desk, and Analytics. We delivered a real-time sync for 100% stock accuracy in under 6 weeks.

The Outcome: The client achieved full digital independence with a lower TCO and zero operational failure during their peak transition period.

FAQs

An API developer designs and maintains the secure bridges between software. They handle architecture, security (OAuth2), and documentation for platforms like SAP, Zoho, and HubSpot.

  1. Public APIs: Open for external developers.
  2. Private APIs: Internal to an organization for efficiency.
  3. Partner APIs: Shared with strategic business allies.
  4. Composite APIs: Combining multiple data calls into one for higher performance.

For beginners, understanding APIs can be simplified by comparing them to a restaurant's service model. Imagine an API as a waiter who takes your order (a request) and conveys it to the kitchen (a system). The kitchen prepares your meal (processes the request) and the waiter delivers the dish back to you (the response). In digital terms, when an application wants to access data or functionalities from another service, it sends a request through the API. The API then queries the relevant system for that information or action and returns the response to the requesting application. This interaction allows different software applications to communicate and share resources efficiently.

A familiar example of an API is the process of searching for flights on a travel website. When you enter your travel dates and destination, the website uses the airlines’ APIs to retrieve available flights and displays them for you. The APIs act as intermediaries, allowing the travel service to access the airlines' databases without needing direct access to their internal systems.

In simple terms, an API is a set of rules and protocols that allows one software application to access the services and data of another. It’s a bridge that enables two different systems to communicate with each other, allowing developers to tap into functionalities or data without having to build those features from scratch.

A real-time API example is the streaming of live sports scores. Websites and mobile apps use these APIs to fetch and display live game scores from various sports leagues instantly. This allows fans to follow their favourite teams and games in real time, even if they cannot watch the game live. The APIs ensure that the data is updated continuously, providing the latest scores and game statistics as they happen.
