From understanding HTTP and JSON to mastering REST or GraphQL frameworks, you’ll gain practical experience through live coding exercises tailored to address real‑world challenges and specific technical projects in your daily workflow.
APIs training
Build better systems with APIs (Application Programming Interfaces) - REST and GraphQL. Learn how services connect, share data, and power software across the web.
Develop in-demand API skills that enhance your technical capabilities
Why choose APIs?
APIs are how software talks. REST and GraphQL are at the heart of modern app development, connecting everything from websites and mobile apps to enterprise systems. If you're working in development, understanding APIs is essential.
This training will teach you to write GraphQL queries exploiting features including arguments, variables and directives. Plus, you’ll learn to configure a REST API in terms of caching, compression and idempotence.

FAQs
By completing a StayAhead APIs courses, you’ll strengthen your ability to design scalable solutions, streamline systems, and support digital transformation initiatives.
What are APIs?
APIs, or Application Programming Interfaces, are tools that allow different software systems to talk to each other. They define a set of rules and protocols that enable one application to request data or functionality from another, without needing to know how the other system is built internally.
APIs are used everywhere – from linking websites to payment gateways, to microservices in enterprise systems. They help software work together efficiently, making them a vital part of modern development.
What’s the difference between REST and GraphQL?
The key difference between REST and GraphQL lies in how they handle data requests and responses.
REST is an architectural style that uses fixed endpoints for each resource and returns full datasets. As a result, clients often have to make multiple requests to get all the information they need.
GraphQL, on the other hand, lets you query exactly what you need. Instead of having multiple endpoints, GraphQL uses one endpoint and lets the client define the structure of the response, offering more control and efficiency for complex applications.
Can I take both courses?
Are the courses live or self-paced?
All API courses are delivered as live virtual classroom training, led by expert instructors, with hands-on labs and real-time support.
