In this blog we are going to learn about how to expose an Apex method  as a REST resource using @HttpGet annotation<\/strong>.<\/p>\n\n\n\n

\n

–> REST annotation enables you to expose an Apex class or an Apex method as a REST resource. In salesforce, there are six REST annotations, that is :<\/p>\n\n\n\n

1). @RestResource(urlMapping=’\/your url’)<\/p>\n\n\n\n

2). @HttpGet<\/p>\n\n\n\n

3). @HttpPost<\/p>\n\n\n\n

4). @HttpPut<\/p>\n\n\n\n

5). @HttpPatch<\/p>\n\n\n\n

6). @HttpDelete<\/p>\n\n\n\n

–> Classes with REST annotation should be defined as global.<\/strong><\/p>\n\n\n\n

–> Methods with REST annotation should be defined as global static.<\/strong><\/p>\n<\/div>\n\n\n\n

@Httpget<\/h3><\/div>
\n

–> @HttpGet is used at method level. This method is called when a HTTP GET  request is sent. To expose your apex class as REST resource you should use @RestResource(urlMapping=’\/your url’) annotation at class level as shown below.<\/p>\n\n\n\n

@RestResource(urlMapping='\/your_url')\nglobal class restExample {\n\t\n    @HttpGet\n    global static void exampleMethod() {\n        \n        \/\/ Write your code here \n    }\n}<\/pre>\n\n\n\n
–> Here url mapping is relative to https:\/\/instance.salesforce.com\/services\/apexrest\/.<\/p>\n\n\n\n
–> If your class is in namespace say ‘abc’, then API  url must be as follows:<\/p>\n\n\n\n
