**Summary:**
The article discusses the importance of API-led connectivity in improving API reuse and organizational agility. It highlights how APIs play a crucial role in enabling different applications to communicate and why API-led connectivity is essential for modern enterprise applications. The article also emphasizes the benefits of API-led connectivity and the challenges associated with API management. It delves into the components of API-led connectivity and provides insights into IBM’s modular approach to API-led connectivity.

API-led connectivity has become increasingly important in the digital age, where real-time, personalized, and connected user experiences are expected across different platforms. As enterprise applications continue to evolve to meet these demands, the integration between applications has become crucial. However, manually building point-to-point integrations is time-consuming, inefficient, and costly. Organizations need a better way to consume and share data and a more flexible and agile way to add new features and solutions. This is where application programming interfaces (APIs) come into play. API-led connectivity, also known as API-led integration or API connectivity, addresses these requirements and helps organizations break down data silos, improve collaboration, respond to change quickly, and increase innovation.

APIs serve as a modern, efficient way to allow others to access and consume an organization’s data and services, enabling companies to open their application data and functionality throughout their ecosystem. The adoption of APIs has skyrocketed in recent years, with an estimated 75 percent of all enterprises projected to be using APIs by next year.

While APIs are transforming the way business is done, they can become unwieldy. A typical organization has approximately 15,564 APIs in use today. This can pose challenges when changes occur, making it difficult for IT staff to keep up with coding APIs by hand.

API-led connectivity is a modern methodology that replaces complex point-to-point integration styles, enabling a more flexible, scalable, and agile architecture through reusable APIs. This approach helps organizations reduce integration complexity and cost, improve accuracy, provide consistent customer experiences, gain better visibility and control, and adapt faster to changing business requirements and technological advancements.

API-led connectivity encompasses two complementary technologies: application integration and API management. The application integration platform that supports APIs provides an opportunity to change the way IT teams operate, enabling business technologists and less experienced developers to compose apps and integrations. API management software allows organizations to govern, manage, secure, and monetize APIs. Both are key components of the IBM iPaaS solution.

IBM uses a modular but integrated approach to API-led connectivity, providing solutions such as IBM API Connect and IBM App Connect to support the entire API lifecycle and enable providers to create, manage, secure, and share APIs within and outside the organization.
