Process builder allows you to do the below actions:
Workflows can only handle four types of actions:
Callout Class:
public class CalloutClass {
public static HttpResponse getInfoFromExternalService() {
HttpRequest req = new HttpRequest();
req.setEndpoint('http://api.salesforce.com/foo/bar');
req.setMethod('GET');
Http h = new Http();
HttpResponse res = h.send(req);
return res;
}
}
Mock Http Response Generator Class:
@isTest
global class MockHttpResponseGenerator implements HttpCalloutMock {
global HTTPResponse respond(HTTPRequest req) {
System.assertEquals('http://api.salesforce.com/foo/bar', req.getEndpoint());
System.assertEquals('GET', req.getMethod());
HttpResponse res = new HttpResponse();
res.setHeader('Content-Type', 'application/json');
res.setBody('{"foo":"bar"}');
res.setStatusCode(200);
return res;
}
}
Callout Test Class:
@isTest
private class CalloutClassTest {
@isTest static void testCallout() {
Test.setMock(HttpCalloutMock.class, new MockHttpResponseGenerator());
HttpResponse res = CalloutClass.getInfoFromExternalService();
String contentType = res.getHeader('Content-Type');
System.assert(contentType == 'application/json');
String actualValue = res.getBody();
String expectedValue = '{"foo":"bar"}';
System.assertEquals(actualValue, expectedValue);
System.assertEquals(200, res.getStatusCode());
}
}
Sample Code:
//Metadata Service
MetadataService.MetadataPort service = new MetadataService.MetadataPort();
ServiceCreation.SessionHeader = new MetadataService.SessionHeader_element();
ServiceCreation.SessionHeader.sessionId = UserInfo.getSessionId();
//Metadata for remote site settings
MetadataService.RemoteSiteSetting remoteSiteSettings = new MetadataService.RemoteSiteSetting();
remoteSiteSettings.fullName = 'Google';
remoteSiteSettings.url = 'https://www.google.com';
remoteSiteSettings.description = 'Remote site settings created from apex';
remoteSiteSettings.isActive = true;
remoteSiteSettings.disableProtocolSecurity = false;
MetadataService.SaveResult[] results = service.createMetadata(new List<MetadataService.Metadata> { remoteSiteSettings });
for(MetadataService.SaveResult sr : results){
if(result.success){
//Success
system.debug('Sucess - ' + result);
}else{
//Failed
system.debug('Failed - '+ result.errors[0].message);
}
}
Note: You need to import all the metadata classes from Metadata WSDL to get this working.
ChangeSets is one of the tools that Salesforce provides for developers to migrating metadata and configuration changes between environments. There are some limitation in ChangeSets. Here are the limitations of ChangeSets, that is why developers need alternative deployment solutions to ChangeSets.
