Send SMS using Twilio Salesforce Library

SMS is still one of the best way to connect with customer .

This blog will be explaining how to use the twilio-salesforce helper library to send SMS. As usual we will implement a small application for it. We will add “Send SMS” button on Account. After clicking “Send SMS” button Salesforce user can type message and send to phone number of that Account.

Steps:

1) download the twilio-salesforce library from GitHub.

 

2) If you don’t have Force.com migration tool install from here.

3) Extract downloaded twilio-salesforce zip file and edit install/build.properties
  to insert your Salesforce username and password. append security token to
    your password.

   Open command line to the install folder, then deploy using Ant:    

    Command : $ ant deployTwilio

4) Sign up for twilio account by trial pack you can send SMS to verified phone
     numbers only.

     (If you need you can get paid service so you can send SMS without
     verifying phone numbers).

5) Get first number :

     Log in to twilio Click on Phone Numbers and get first number(SMS will be
     send from this Number ).

     In verified Caller Ids sub-tab you can verify phone numbers(You will need
     verified numbers to send SMS if you are using trial pack).

6) Create Custom Object SMS :

     Object Name SMS (API Name : SMS__c)

     Create fields as below, this object will be used to save SMS log.

 

7) Create Visualforce Page : Send_SMS

<apex:page standardController="Account" Extensions="Send_SMS_Controller"
  showHeader="false" sidebar="false">
     <apex:form >
           <apex:pageBlock id="msgs"> 
                <apex:pageMessages ></apex:pageMessages>
                 Body : <br/>
                <apex:inputText id="smsBody" value="{!smsBody}"   
      style="width:400px; height:50px;"/>
                       <br/>
                <apex:commandButton action="{!send}" value="Send" 
     id="sendButton" reRender="msgs" rendered="{!hasNumber}"/>
                <apex:commandButton action="{!getReturn}" value="Return to Account"
      id="returnButton" reRender="msgs" rendered="{!NOT(hasNumber)}"/>
             </apex:pageBlock>
       </apex:form>
  </apex:page>

8) Create Apex Class : Send_SMS_Controller

public class Send_SMS_Controller {
    public String smsBody {get; set;}
    public boolean hasNumber {get; set;}
    private final String  fromNumber = '+19545732804';// get it from twilio
      //after login click Phone Numbers tab in left sidebar

    private string dialCode = '+91'; // Add your dial Code of your country.
    public Send_SMS_Controller(ApexPages.StandardController controller) {
       hasNumber = true;
    }
    public PageReference Send()
    {
        String account = ‘your twilio Account SID’; // Account SID on home tab
        String token   =   'twilio Account AUTH Token';//AUTH Token on home tab
        TwilioRestClient client = new TwilioRestClient(account, token);
        
        Id accountId = ApexPages.currentPage().getParameters().get('id');
        String baseUrl = URL.getSalesforceBaseUrl().toExternalForm();
        Account a = [select Phone from Account where Id = :accountId];
 
        if(a.Phone != null)
        {
            String phoneNumber = a.Phone;
            if(!phoneNumber.Contains(dialCode))
            phoneNumber = dialCode+phoneNumber;// If by default dialCode is not 
             //on Phone number we will ad it.
            System.debug('phoneNumber'+phoneNumber);
             Map<String,String> params = new Map<String,String> {
            'To'   => phoneNumber,
            'From' => fromNumber,
            'Body' => smsBody
             };
             TwilioSMS sms = client.getAccount().getSMSMessages().create(params);
             SMS__c sentSMS = new SMS__c(From__c = fromNumber,To__c = phoneNumber,
        Account__c = accountId, Body__c = smsBody);
             insert sentSMS;
             
             
        }
        else
        {
             ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR, 'This Account have No Phone Number Click Return to Account'));
             System.debug('Message is set');
             hasNumber = false;
             return null;
        }
        
        pagereference redirect = new PageReference(baseUrl+'/'+accountId);
        return redirect;
    }
     public PageReference getReturn()
     {
        return new PageReference(URL.getSalesforceBaseUrl().toExternalForm()+'/'+ApexPages.currentPage().getParameters().get('id'));
