Gartner defines the application programming interface (API) management market as the market for software to manage, govern and secure APIs. APIs modernize IT architectures. They provide context, tools and resources to generative and agentic AI programs and provide access to systems, services, partners and data services. API management tools enable organizations to plan, deploy, secure, operate, version control and retire APIs, regardless of their size, region or industry.
Gartner defines integration platform as a service (iPaaS) as a vendor-managed cloud service that enables end users to implement integrations between applications, services and data sources, both internal and external to their organization. iPaaS enables end users of the platform to integrate a variety of internal and external applications, services and data sources for at least one of the three main patterns of integration technology use: data consistency, multistep process and composite services. These integration use cases are most commonly implemented via intuitive low-code or no-code developer environments, though some vendors provide more complex developer tooling.
