APIs have become essential for modern businesses to facilitate data sharing and collaboration both internally and externally, serving as a digital supply chain that connects vendors and customers. However, there is a gap in tools for leveraging the data flowing through these APIs. Traditional business analytics focus on either offline transactional data or online usage metrics, leaving out insights from API-driven interactions. To address this, an effective API analytics system should capture both technical metrics and business-relevant data, allowing organizations to track customer journeys, monitor product retention rates, and optimize marketing strategies. Such a system must also allow business users to create actionable insights through dashboards tailored to various team needs. Challenges in deploying API analytics include maintenance costs, compliance risks, and ensuring ease of use for non-technical users, emphasizing the necessity of self-service analytics for agile development and innovation.
