dynamically get session id rest api

Hi All,

I am trying to connect one sf org to anaother. I am using the below class to initiate the call from command button. I copied session id of target org and hard coded here in the class which then worked. But for next time it expires and i get invalid session id.

Can anyone help me out how i can dynamically have the session id of source org, so that i need not to hard code it.

public class Apex_Rest_DemoController {
    
    public String response{get;set;}
    public String accName{get;set;}
    public String accPhone{get;set;}
    public String accWebsite{get;set;}
    
    public PageReference CreateAccount() {
        //find access token using Auth 2.0 
       String Access_Token = '00D28000000Heme!AQ8AQAFOnSjXlGvbNT9JXj5vcC2XjQyFtz8ls_x0IMmoDuX91WDLvb9j5qficiTwQpCGjTYIRCUOmvwQOlWvP2.0HPA3x9M.';
       
        Httprequest req=new httprequest();
        String domainName='ap2.salesforce.com';

        String endPointURL='https://'+domainName+'/services/data/v34.0/sobjects/Account';
        req.setendpoint(endPointURL);
        req.setHeader('Content-Type', 'application/xml; charset=utf-8');
        req.setBody('<?xml version="1.0" encoding="UTF-8" ?><request><name>'+accName+'</name><phone>'+accPhone+'</phone><website >'+accWebsite+'</website > </request>');
        req.setmethod('POST');
        req.setHeader('Authorization','Authorization: Bearer '+Access_Token);
        //req.setHeader('Authorization','Bearer '+Access_Token);
        //req.setHeader('Authorization', 'OAuth '+UserInfo.getSessionId());
        Http http = new Http();
        HTTPResponse res = http.send(req);
        response=res.getbody();
        System.debug('****************res.getStatusCode();'+res.getStatusCode());
        System.debug('****************res.getbody();'+res.getbody());
        return null;
    }
}

Use   UserInfo.getSessionId() to get dynamically session id and assigned it to 

String Access_Token =  UserInfo.getSessionId();

Hi,

You need to make a call for access token instead of har coding it which can be in following format. as a response you will get access token that you can use in the above code.

Http h = new Http();
String body='grant_type='+password+'&client_id='+CLIENT_ID+'&client_secret='+CLIENT_SECRET+'&username=username&password=password+securitytoken';
HttpRequest req = new HttpRequest();
req.setEndpoint('https://login.salesforce.com/services/oauth2/token');
req.setMethod('POST');
req.setBody(body);
HttpResponse res = h.send(req);

Thanks

Hi ❤Code, 
One option is to  make a SOAP call using either the enterprise wsdl or the partner wsdl of the target environment and call the login method that takes the username & password+securityToken and get the sessionId as reponse.

Hi Pallab,

Anyway to acomplish this using rest api. The only point i am stuck is how to get the session id of my target sfdc org without hardcoding.

Hi.. I get you want to make a REST call to accomplish this. However to make this REST call you need an active connection (sessionId). So before making the REST call, make a SOAP call and get the session id in response. and subsequently use this session Id  to make the REST call. Hope am making sense :-)

(1)
this line:request.setHeader('Authorization', 'OAuth ' + SESSION_ID);
should be :req.setHeader('Authorization', 'OAuth ' + SESSION_ID);

(2) also try iusing: req.setHeader('Authorization', 'Bearer + SESSION_ID);
Best of Luck :-)

Hi Pallab,

Tried the above, but no luck..Getting Invalid Session error

Hi..
Can you please validate that your SOAP call to the other salesforce instance worked? (Lets call its SFDC-B)

You have used credentials of a SFDC-B' User while making the SOAP call to SFDC-B. If you login to SFDC-B and verify the user's login history to confirm the SOAP call actually made a call to SFDC-B and returned a SessionId?

Hi Pallab,

Thanks for helping me out. I have resolved the issue. I made a OAuth call to target org using consumer, key, client secret, uid and password. Captured the sessionid and used that one making a rest call to rest resource.

Hi,

Below is what I am doing:

        byte[] data = IOUtils.toByteArray(new FileInputStream(f));
                JSONObject content = new JSONObject(); 
                if (attachment != null) {
     content.put("Name", attachment); 
                }
                content.put("Body", new String(Base64.encode(data))); 
                content.put("ParentId", caseid);

                builder = new PostMethod("https://gus.salesforce.com/services/data/v20.0/sobjects/Attachment/");
                builder.setRequestEntity(new StringRequestEntity(content.toString(), "application/json", null));
                builder.setRequestHeader("Authorization","OAuth " + SessionId); 
                httpclient.executeMethod(builder);

This code works for me but for files for smaller size. I tried attaching file of 50+ MB and it threw bad request error for me. Can you please help. I need a solution for attaching files of larger size (around 1GB).

Regards,

Hi,

I have subscribed for developer account in Salesforce. Now I want to do some API calls to Salesforce. So as prerequisite I have created a connected app called Mule in sales force and I have enabled OAuth in it. API is enabled for my profile. 

As mentioned in the link ( https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/quickstart_oauth.htm ) I am trying to get SessionID. I am using below link command.

curl https://login.salesforce.com/services/oauth2/token -d "grant_type=password" -d "client_id=******" -d "client_secret=*****" -d "username=mylogin@salesforce.com" -d "password=mypassword123456"

I got error {"error":"invalid_grant","error_description":"authentication failure"}

I tried same from postman using POST method, gave userid and password

https://login.salesforce.com/services/oauth2/token?grant_type=password&client_id=3MVG9YDQS5WtC11opKfz4w0XYTmO4dfE9Bwx4Ao7fy5fMPAuZfRBQFIIkUv78ln8gZ.bw3W2GicyQLnZyVu1I&client_secret=4284160506975427817

RESPONSE:
{
  "error": "invalid_grant",
  "error_description": "authentication failure"
}

can some one please help ?
