A Web API is a broader term that can include REST, SOAP, or other protocols.<\/p>\n<h4 data-start=\"487\" data-end=\"527\">2. <strong data-start=\"495\" data-end=\"527\">Is every REST API a Web API?<\/strong><\/h4>\n<p data-start=\"528\" data-end=\"682\">Yes, every REST API is a Web API because it uses web technologies (like HTTP). However, not all Web APIs are RESTful \u2014 some may use SOAP or other formats.<\/p>\n<h4 data-start=\"684\" data-end=\"733\">3. <strong data-start=\"692\" data-end=\"733\">Which is better: REST API or Web API?<\/strong><\/h4>\n<p data-start=\"734\" data-end=\"934\">REST API is often better for modern web and mobile applications due to its simplicity, stateless design, and use of JSON. Web API is more flexible and may be preferred in legacy or enterprise systems.<\/p>\n<h4 data-start=\"936\" data-end=\"973\">4. <strong data-start=\"944\" data-end=\"973\">Can a Web API be RESTful?<\/strong><\/h4>\n<p data-start=\"974\" data-end=\"1141\">Absolutely. A Web API becomes a REST API when it follows REST constraints like statelessness, resource-based URLs, and use of HTTP methods like GET, POST, PUT, DELETE.<\/p>\n<h4 data-start=\"1143\" data-end=\"1195\">5. <strong data-start=\"1151\" data-end=\"1195\">When should I use REST API over Web API?<\/strong><\/h4>\n<p data-start=\"1196\" data-end=\"1424\">Use REST API when building scalable, maintainable web or mobile apps that benefit from lightweight communication. Choose a broader Web API (like SOAP) for complex enterprise systems needing advanced security or protocol support.<\/p>\n<h4 data-start=\"1426\" data-end=\"1465\">6. <strong data-start=\"1434\" data-end=\"1465\">Why is REST API so popular?<\/strong><\/h4>\n<p data-start=\"1466\" data-end=\"1623\">REST APIs are popular because they are easy to use, support JSON (which is lightweight and readable), and scale well in modern cloud and mobile environments.<\/p>\n<h4 data-start=\"1625\" data-end=\"1685\">7. <strong data-start=\"1633\" data-end=\"1685\">Is Web API obsolete now that REST API is common?<\/strong><\/h4>\n<p data-start=\"1686\" data-end=\"1841\">No. Web API is still widely used and offers broader compatibility, especially in older or complex enterprise systems that require SOAP or custom protocols.<\/p>\n<hr \/>\n<h2>Related Reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.kaashivinfotech.com\/blog\/open-source-vs-closed-source-key-differences\/\">Open Source vs Closed Source: Key Differences Explained<\/a><\/li>\n<li><a href=\"https:\/\/www.kaashivinfotech.com\/blog\/what-is-wordpress-beginners-guide\/\">What Is WordPress?
