6 Best API Testing Courses for Beginners
API testing is a fundamental skill for anyone building or maintaining web services, and these six beginner‑focused courses give you a practical entry point. They cover tools such as Postman, Gatling, and REST Assured, and introduce core concepts like request construction, response validation, and basic automation. The selection is split between Udemy and Coursera, with prices ranging from $19.99 to $79.99, so you can choose a budget that matches your needs while still gaining hands‑on experience.
Each course takes a slightly different approach: the Postman tracks focus on manual testing and API workflow, the Gatling offering adds a Java‑based stress‑testing angle, and the REST Assured titles concentrate on code‑driven automation in Java. Consider your preferred toolset, whether you want a broader overview or a deep dive into a specific framework, and pick the option that aligns with your current projects and learning style.

How these 6 courses were chosen
Every course below is a real, currently listed course from Udemy, Coursera, matched to "api testing" by our catalog and ordered by our CourseAsk score. Courses whose own title names the topic rank above those only tagged with it.
The grade on each entry scores how much the provider publishes about the course before you pay — the length and detail of the description, whether it lists learning outcomes and objectives — and whether a named university or institution stands behind it. A is fully documented and institution-backed; E is little more than a title and a price. Courses with almost nothing published are left ungraded rather than marked down, because an unknown course and a poor one are not the same thing.
There are no star ratings on this page — the course feeds we license do not include them, and we would rather leave a column out than fill it with a number we cannot stand behind. What we do have is price: these range from $19.99 to $79.99, as listed by the provider when we last updated the page.

What the prices here tell you
The 6 priced courses on this page run from $19.99 to $79.99, with the middle of the range around $49.00 — a spread of $60.00. The options are closely priced, so cost is unlikely to be your deciding factor. A higher price on this page usually reflects who is behind the course rather than how much material it contains, so it is worth opening two or three at different price points and comparing their syllabus before deciding.
Who is behind these courses
These courses come from Udemy and Coursera. The platforms differ in how they sell: some charge once per course, others expect a subscription, and the listed price is not always what you pay at checkout after a promotion.
Before you enrol
Open the provider’s own page and check three things this comparison cannot tell you: when the course was last updated, what the syllabus actually covers in its later sections, and what recent learners say. Prices shown here are the provider’s listed price when we last rebuilt this page on 18 September 2026 — they change often, and a promotion can move them substantially. We earn a commission if you enrol through our links, which costs you nothing and never affects the order courses appear in.
