    What is API?

    Definition

    An API (Application Programming Interface) is a set of protocols and rules that allows two software systems to communicate and exchange data. APIs enable integrations, allowing a learning platform to pull user data from an HR system, or a mobile app to access course content from an LMS. APIs are fundamental to modern software architecture.

    APIs in enterprise learning stacks

    Well-designed APIs make learning platforms flexible and future-proof. A platform with robust APIs can integrate with HR systems, send data to analytics platforms, and connect to AI agents. Poor or missing APIs force workarounds, limit extensibility, and create vendor lock-in. API-first architecture is a hallmark of modern learning infrastructure.

    API — frequently asked

    REST (Representational State Transfer) is most common: HTTP endpoints returning JSON. GraphQL is gaining adoption for more efficient data queries. Standards like xAPI (Experience API) standardize learning data exchange.

    APIs enable custom integrations with internal systems, automated workflows, and third-party extensions. They reduce manual data entry and connect learning to business outcomes.

    Authentication (API keys, OAuth), authorization (role-based access), rate limiting, encryption (HTTPS), and audit logging. Secure APIs require attention during implementation.

    From definition to done.
