[WSO2 Integration Summit Nairobi 2019] Role of Integration in an API Driven World
1 like375 views
This document discusses the role of integration in an API-driven world. It covers why APIs are important for digital transformation and new revenue opportunities. It describes code-first and contract-first API design approaches. The document also discusses using an integration gateway as an "API facade" and how the WSO2 Enterprise Integrator can serve this role. Additional topics covered include API implementation strategies, a case study of a "Super City" implementing an API initiative, and capabilities of the WSO2 Enterprise Integrator and Micro Integrator for API-driven integration.
