RestContext.response.statusCode can be used to set HTTP Status Code for Salesforce Apex REST API.
Sample Apex Code:
@RestResource( urlMapping='/RecordFinder/V1/*' )
global with sharing class RESTAPIController {
@HttpGet
global static void doGet() {
switch on RestContext.request.requestURI.substringAfterLast( '/' ) {
when 'CheckAccountAvailability' {
verifyExistingAccount();
} when 'CheckContactAvailability' {
verifyExistingContact();
} when else {
String strResponse;
Map < String, String > mapResponse = new Map < String, String >();
mapResponse.put(
'errorMessage',
'Please check the endpoint URL and Path'
);
strResponse = JSON.serialize(
mapResponse
);
RestContext.response.addHeader(
'Content-Type',
'application/json'
);
RestContext.response.responseBody = Blob.valueOf(
strResponse
);
RestContext.response.statusCode = 406;
}
}
}
