Join Larsen & Toubro in GIFT City, Gandhinagar as an API Integration Developer Intern. This entry-level internship is designed for students and recent graduates who learn best by building, shipping and getting real feedback on API development and third-party integration work. About the role As an API Integration Developer Intern at Larsen & Toubro, your core focus will be connecting systems that were never designed to talk to each other, and keeping the contract stable. You are attached to a named mentor, join the team's stand-ups and reviews, and are trusted with work that matters rather than filler tasks. Questions are encouraged, your output is reviewed properly, and you get the feedback you need to actually improve. What you'll do day to day • Work on connecting systems that were never designed to talk to each other, and keeping the contract stable alongside the core team • Use REST APIs, JSON & XML, Postman, OAuth 2.0 & API Keys, Webhooks on live, production-facing problems • Turn your work into clear documentation, notes or decks for reviewers • Take part in reviews and act on the feedback you receive • Collaborate across functions — engineering, product, design or business as the work demands • Follow the team's quality, testing and documentation standards • Track and report your own progress against an agreed plan Skills you'll build You will build practical, demonstrable experience in REST APIs, JSON & XML, Postman, OAuth 2.0 & API Keys, Webhooks, Node.js or Java, API Documentation (Swagger), Error Handling & Retries, Git, SQL — the exact toolkit that separates a hireable fresher from a CV full of coursework. No prior work experience is required. Curiosity, problem-solving ability and a willingness to learn matter far more here than a polished résumé, and every one of these skills is taught on the job.
