Objective

Designing APIs for use over the web is a key part of most web development projects these days. Knowing the best way to design them with longevity, testability and reliability in mind is important. The goal of this course is for the student to be familiar with APIs, the concept of API Design and what is essential to design of an API-based solution. By explaining API Design steps and API Design approaches, the student will be familiar with all these concepts in a practical way. Then the student will be familiar with different API styles, and obtain a deeper level of knowledge about REST and its key difference and advantageous over the other styles. Finally, the student will understand security and performance concerns.
This course is 100% virtual thanks to the comprehensive tutorial videos and content made for this course.
The student will pass this course after submitting required assignments, quiz and projects.
