API Integration - End to End Web Development teaches you to connect front-end applications to the services behind them. It covers how APIs work, how RESTful and GraphQL APIs are designed and documented, and how a web app calls, secures and displays them.

By the end, you can design and implement RESTful APIs, build a simple GraphQL API, make authenticated requests with Fetch and Axios, debug failed calls, and present API data in a real UI - across 22 short video lessons, 7 readings and 10 assignments.

It's course 3 of Board Infinity's End-to-End Web Development: UI, Databases, APIs specialization on Coursera, the step that ties a user interface and its database together.

03 What you'll learn

Four outcomes. Real, connected web apps.

Each module takes you a step further, from how APIs work to putting their data in front of users.

Module 1

Design RESTful APIs

Understand API types, then design, implement, document with Swagger, and version and deprecate RESTful APIs.

Module 1

Build with GraphQL

Learn what GraphQL is, where it beats REST, and build a simple GraphQL API of your own.

Make requests with Fetch and Axios, authenticate with OAuth and API keys, and debug and handle API errors.

Module 3

Integrate APIs into real UIs

Display API data in the interface, handle dynamic data as it changes, and cache responses for speed.

08 FAQ

Common questions

Everything learners ask before enrolling, answered plainly.

About the course

Module one covers what APIs are, the types of APIs, designing and implementing RESTful APIs, documenting them with Swagger, versioning and deprecation, and building a simple GraphQL API. Module two covers making requests with the Fetch API and Axios, handling responses, authentication with OAuth and API keys, securing requests, and debugging and error handling. Module three covers displaying API data in the UI, handling dynamic data and caching API data.

Coursera lists this as an intermediate-level course, and the specialization recommends basic web development knowledge. Comfort with HTML, CSS and JavaScript helps - the first two courses of the specialization, Crafting User Interface and Managing Databases, cover the UI and data layers this course connects.

The current enrollment options and price for your region are shown on the Coursera course page. The course is included with a Coursera Plus subscription, and Coursera's financial aid is available for eligible learners. Enrollment also includes the whole End-to-End Web Development specialization track.

About 10 hours of total learning across 3 modules, with 22 video lessons, 7 readings and 10 assignments. Coursera estimates 1 week at 10 hours a week. It's fully self-paced - deadlines flex around your schedule.

The first two modules each have three practice quizzes, one per lesson, and a one-hour graded quiz at the end. The third module has a practice quiz and a 30-minute graded quiz - 10 assignments in all. A reading after each lesson goes further into topics like API design, authentication and authorization, and error handling.

Yes - this page is Board Infinity's own overview of our course. Enrollment, payment, video lessons, grading and the certificate all happen on Coursera, where the course is hosted. Think of this page as the detailed tour before you head there.

Career & certificate

Yes. Completing the graded quizzes earns you a shareable certificate from Board Infinity, issued through Coursera with its own verification link. You can add it to your LinkedIn profile, resume or CV, and the same completed work counts toward the full specialization certificate.

It supports full-stack, front-end, back-end and API developer roles, as well as integration engineering and API testing - any role where an application talks to services over APIs.

Two ways. The certificate goes in your LinkedIn Licenses & Certifications section via Coursera's one-click add. Just as valuable is naming what you can do: a line like “Designed and documented RESTful APIs with Swagger, built a GraphQL API, and integrated authenticated APIs into a web UI with Fetch and Axios” gives interviewers something concrete to ask about.

Yes. Module one covers RESTful API basics, design, implementation and documentation, then introduces GraphQL, its benefits, and building a simple GraphQL API.

This is the final course of the specialization. If you haven't taken them, the first two courses are Crafting User Interface - End to End Web Development (~14 hours) and Managing Databases - End to End Web Development (~13 hours). Completing all three earns the specialization certificate.
