Salesforce rest api integration to update a record.

Today we will trying to cover the topic Salesforce rest api integration by taking example of two Salesforce systems.

First let's see when to use rest api as we have lot of other Salesforce api.

Rest api is a simple and power webservice based on restfull principles and it use rest resource and HTTP methods to expose functionalities.It supports both XML and JSON .Rest api has light weight request and response frame work and it is good for mobile and web apps.
Let say I have two system as SYSTEM A and another system as SYSTEM B.

What we will doing today is we will try to update a record in SYSTEM B using rest api from SYSTEM A.

REST API WEBSERVICE FROM SYSTEM B:

@RestResource(urlMapping='/updaterecord/*')
   global with sharing class updateAccount {
     @httpput
      global Static string fetchAccount(string Name,string NewAccountNumber,string OldAccountNumber){
      Account obj=new account();
      obj=[select id,name,AccountNumber from account where AccountNumber=:OldAccountNumber]; // fetching account by old account number.
      obj.AccountNumber=NewAccountNumber; // updating account with new account number.
      update obj;
        return 'Success';
      }
   }

CONNECTED APP IMAGE FROM SYSTEM B:

Note down the Consumer key,Consumer secret(We need to provide it SYSTEM A for authentication purpose along with username,password,security token of user which SYSTEM A will be using for authentication).

APEX CONTROLLER FROM SYSTEM A :

public class restApiToUpdateRecords{


private string cKey='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
private string cSecret='XXXXXXXXXXXXXXXXXXXXX';
private string uName='XXXXXXXXXXXXXXXXXXX';
private string passwd='Password+SecurityToken';
public static list<resultWrapper> listWrap{get;set;}

public restApiToUpdateRecords()
{
listWrap=new list<resultWrapper>();

}



public class responseWrapper{

public string id;
public string access_token;
public string instance_url;

}

public string getRequestToken()
{
string reqBody='grant_type=password&client_id='+cKey+'&client_secret='+cSecret+'&username='+uName+'&password='+passwd;                                   

Http h=new Http();
HttpRequest req=new HttpRequest();
req.setBody(reqBody);
req.setMethod('POST');
req.setEndpoint('https://login.salesforce.com/services/oauth2/token');

HttpResponse hresp=h.send(req);
responseWrapper wResp=(responseWrapper) JSON.deserialize(hresp.getBody(),responseWrapper.class);
system.debug('Instance url'+wResp.instance_url);
system.debug('session id'+wResp.access_token);
return wResp.access_token;


}

public void getConList()
{

list<account> accList1=new list<account>();
String accToken;
string responseBody;
string Jsonstring='{"Name":"Acc test 1","NewAccountNumber":"456","OldAccountNumber":"123"}';
string accIdToupdate='0017F00001Xf1RO';
string endPoint='https://ap5.salesforce.com/services/apexrest/updaterecord/';
restApiToUpdateRecords obj=new restApiToUpdateRecords();
accToken=obj.getRequestToken();
system.debug('access token'+ accToken);
if(accToken!='')
{
Http h1=new Http();
HttpRequest req1=new HttpRequest();
req1.setHeader('Authorization','Bearer '+accToken);
req1.setHeader('Content-Type','application/json');
req1.setBody(Jsonstring);
req1.setMethod('PUT');
req1.setEndpoint(endPoint);
HttpResponse hresp1=h1.send(req1);


}



}

public class resultWrapper{

public string id{get;set;}
public string name{get;set;}


}


}


VISUALFORCE PAGE FROM SYSTEM A TO DISPLAY DATA:

<apex:page controller="restApiToUpdateRecords">
<apex:form >
<apex:pageBlock >

 <apex:pageblockButtons >
 <apex:commandButton value="Update record" action="{!getConList}"/>

 </apex:pageblockButtons>

 </apex:pageBlock>
 </apex:form>
</apex:page>
