C.1. Step – Step for Create Callout Method Integration Based on Triggers
1. Buat Class Apex untuk Mendapatkan Access Token
Gunakan kode berikut:
public class REST_CallOut_SalesforceOAuth {
// Metode untuk mendapatkan Access Token dari org tujuan
public static String getAccessToken() {
// URL Endpoint untuk OAuth 2.0 token
String tokenEndpoint = 'https://login.salesforce.com/services/oauth2/token';
// Setup HTTP Request
HttpRequest req = new HttpRequest();
req.setEndpoint(tokenEndpoint);
req.setMethod('POST');
req.setHeader('Content-Type', 'application/x-www-form-urlencoded');
// OAuth 2.0 credentials dari Connected App di org tujuan
String clientId = 'YOUR_CONSUMER_KEY'; // Ganti dengan Client ID (Consumer Key)
String clientSecret = 'YOUR_CONSUMER_SECRET'; // Ganti dengan Client Secret (Consumer Secret)
String username = 'YOUR_ORG_TUJUAN_USERNAME'; // Ganti dengan username org tujuan
String password = 'YOUR_ORG_TUJUAN_PASSWORD_AND_SECURITY_TOKEN'; // Gabungan password + security token dari org tujuan
// Set body untuk request, sesuai dengan format OAuth 2.0
String body = 'grant_type=password'
+ '&client_id=' + EncodingUtil.urlEncode(clientId, 'UTF-8')
+ '&client_secret=' + EncodingUtil.urlEncode(clientSecret, 'UTF-8')
+ '&username=' + EncodingUtil.urlEncode(username, 'UTF-8')
+ '&password=' + EncodingUtil.urlEncode(password, 'UTF-8');
req.setBody(body);
// Eksekusi HTTP Request
Http http = new Http();
HttpResponse res = http.send(req);
// Jika responsenya sukses (status 200), ambil token dari response body
if (res.getStatusCode() == 200) {
// Parsing JSON response untuk mendapatkan access token
Map<String, Object> responseBody = (Map<String, Object>) JSON.deserializeUntyped(res.getBody());
String accessToken = (String) responseBody.get('access_token');
// Log token untuk debugging (jangan gunakan ini di produksi)
System.debug('Access Token: ' + accessToken);
// Kembalikan access token
return accessToken;
} else {
// Log jika terjadi kesalahan dan return null
System.debug('Error Response: ' + res.getBody());
return null;
}
}
}
Credentials
CONSUMER_KEY : 3MVG9VMBZCsTL9hna9QaiPuFBAPG4StUl9CkTR0xdSvQBoHmThkUn_UhnTB0k3qZQxcupYINLjheLWe5SU1b0
CONSUMER_SECRET : BB1E7ECC5ACDEA2D7DFD680ACDCECA2360C8AD8E59E2880AC2CBB58041AD7176
USER_NAME : devorg1@saasten.com
PASSWORD : demo1234
SECURITY TOKEN : 7cZapUnBJBo0di1buBHlNvxp
2. Buat Class Apex untuk Melakukan Callout ke Org Tujuan
Setelah mendapatkan token, kita akan menggunakan token tersebut untuk memanggil Salesforce REST API di org tujuan dan mengirimkan data.
Berikut Contoh Codingannya:
public class REST_Callout_Contact {
@future(callout=true)
public static void InsertContactDataToOrg2(Id contactId) {
// Ambil data Contact yang akan dikirim
Contact con = [SELECT Id, FirstName, LastName, Email FROM Contact WHERE Id = :contactId];
// Dapatkan Access Token menggunakan metode yang dibuat sebelumnya
String accessToken = REST_CallOut_SalesforceOAuth.getAccessToken();
if (accessToken == null) {
System.debug('Failed to get access token');
return;
}
String EndPoint= 'https://saastentechnologies65-dev-ed.develop.my.salesforce.com';
// URL Endpoint Salesforce REST API di org tujuan
String URLendpoint = EndPoint + '/services/data/v54.0/sobjects/Contact/';
// Siapkan HTTP Request
HttpRequest req = new HttpRequest();
req.setEndpoint(URLendpoint);
req.setMethod('POST');
req.setHeader('Authorization', 'Bearer ' + accessToken);
req.setHeader('Content-Type', 'application/json');
// Format data Contact ke dalam JSON
String jsonBody = '{"FirstName": "' + con.FirstName + '", "LastName": "' + con.LastName + '", "Email": "' + con.Email + '"}';
req.setBody(jsonBody);
// Eksekusi HTTP Request
Http http = new Http();
HttpResponse res = http.send(req);
// Log hasil response
System.debug('Response Status: ' + res.getStatus());
System.debug('Response Body: ' + res.getBody());
}
}
Berikut Contoh Codingannya
trigger ContactTrigger on Contact (after insert) {
for (Contact con : Trigger.new) {
// Panggil metode untuk mengirim data ke org tujuan
REST_Callout_Contact.sendContactDataToOrg2(con.Id);
}
}
3. Testing dan Verifikasi
C.2. Step – Step for Create Callout Method Integration Based on Button Using Invocable Metode
1. Membuat Invocable Method untuk Pengiriman Data Contact
Contoh Kode:
public with sharing class ContactIntegrationService {
@InvocableMethod(label='Send Contact Data')
public static List<String> sendContactData(List<Id> contactIds) {
List<String> resultMessages = new List<String>();
String accessToken = REST_CallOut_SalesforceOAuth.getAccessToken() //Mendapatkan Access Token
for (Id contactId : contactIds) {
try {
Contact contact = [SELECT Id, FirstName, LastName, Email FROM Contact WHERE Id = :contactId LIMIT 1];
HttpRequest req = new HttpRequest();
req.setEndpoint('https://target-org.my.salesforce.com/services/data/v52.0/sobjects/Contact/');
req.setMethod('POST');
req.setHeader('Authorization', 'Bearer ' + accessToken);
req.setHeader('Content-Type', 'application/json');
Map<String, Object> contactData = new Map<String, Object>();
contactData.put('FirstName', contact.FirstName);
contactData.put('LastName', contact.LastName);
contactData.put('Email', contact.Email);
req.setBody(JSON.serialize(contactData));
Http http = new Http();
HttpResponse res = http.send(req);
if (res.getStatusCode() == 201) {
resultMessages.add('Contact ' + contact.FirstName + ' ' + contact.LastName + ' berhasil dikirim!');
} else {
resultMessages.add('Gagal mengirim Contact ' + contact.FirstName + ': ' + res.getBody());
}
} catch (Exception e) {
resultMessages.add('Error mengirim Contact Id: ' + contactId + '. Pesan error: ' + e.getMessage());
}
}
return resultMessages;
}
}
Poin Penting:
2. Membuat Button untuk Memanggil Invocable Method
Langkah-langkah Membuat Button:
Want to print your doc?
This is not the way.
This is not the way.
Try clicking the ⋯ next to your doc name or using a keyboard shortcut (
CtrlP
) instead.
