Unlike more complex SOAP services, REST web services are <strong data-start=\"816\" data-end=\"859\">lightweight, flexible, and easy to implement<\/strong>. It uses standard methods such as <strong data-start=\"900\" data-end=\"907\">GET<\/strong>, <strong data-start=\"909\" data-end=\"917\">POST<\/strong>, <strong data-start=\"919\" data-end=\"926\">PUT<\/strong> and <strong data-start=\"930\" data-end=\"940\">DELETE<\/strong> to manipulate data, often in the format <strong data-start=\"987\" data-end=\"995\">JSON<\/strong> or <strong data-start=\"999\" data-end=\"1006\">XML<\/strong>. This approach facilitates the exchange of information between websites, mobile applications, ERPs, and other business software, while ensuring a <strong data-start=\"1153\" data-end=\"1184\">software interoperability<\/strong> optimal.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3d19124 elementor-widget elementor-widget-heading\" data-id=\"3d19124\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">What is a REST web service used for?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9e243bb elementor-widget elementor-widget-text-editor\" data-id=\"9e243bb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul><li>The REST web service allows systems to connect and\u2019<strong data-start=\"1303\" data-end=\"1332\">automate processes<\/strong> fluidly.
