5 Easy Steps to Configure Salesforce Live Agent

Live Agent is a native Salesforce tool that provides the ability to interactively communicate with your web site users. Once you have an active deployment of live agent, you will be able to chat with you site visitors in live time. The information collected during the chat can then be saved into your Salesforce instance and reported on. This is a great way to get valuable user feedback and at the same time provide a much needed service to people navigating your website.

You can get started with Live Agent by first contacting Salesforce.com to setup your particular instance of Salesforce with Live Agent. Live Agent does come at an additional cost and it is only available for Enterprise and Performance editions of the Service Cloud.

1. Getting Started:

Once Live Agent is enabled for your org, you will be able to view the following Live Agent options in the start-up menu. Go to Setup -> Build -> Customize -> Live Agent.

Note: If Live Agent is not yet enabled these options will not be listed.

2. Create you user skills

The first step to implementing Live Agent is to set up Skills for users. These skills will allow you to tag the people who will be chatting with your web site visitors. You may want to have a range of skills for subject area experts. For example, you may have a hardware specialist and a software expert. By making good use of the user skills you can route the right questions to the right place quickly. Be sure not to overcomplicate the user skills with too many options, there needs to be at least one employee for each skill in order for the skill to be useful.

3. Create your Live Agent Button

Once you have created the user skills, you can move on to the next step of creating a new button. The button is where you can connect what user skills are needed for people who click on the button. Other settings that are at the button level include; Button images, Pre or Post – Chat Forms, custom agent names, routing type, auto greeting, and Language.
It is highly advisable to carefully review the Chat Buttons & Invitations area of the setup menu because these options will control how the button works on your site. That means the entire out of the box button configuration available from Salesforce.com is located here. If additional features are required for your particular button setup, you will need to customize the Chat Button code with APEX and VisualForce. For example if you would like to set the web page button for the chat initiation to also launch an external support page, this will need to be added into the chat button code by a developer.

4. Customize the Live Agent Configuration

In the last step we looked at all of the site visitor/ customer side of the Live Agent implementation. This part of the setup is where the internal company employee setup is customized. Everything your employees will be looking at from inside the service console will be controlled in this area. The same disclaimer about enhancements is true for this area of the setup as well. Since all the native out of the box configuration is located here it is important to review this carefully. If there is a feature you need to have that is not listed here, please inquire during your purchase consultation as it may require custom APEX in order to implement.

The Live Agent Configuration area entails the Basic Information, User and Profile Assignment, Supervisor Settings, and Chat Transfer Settings.

Basic Information is where custom agent names, auto away, critical wait time (seconds), sneak peek and notifications are specified.

Determine what users are assigned for this configuration, you can set the employees who will have this configuration applied to them by user or by profile:

Next, you can set the chat supervisor settings, a chat supervisor has an additional set of privileges in order to monitor and assist with the other agent’s ongoing chat. For example, a Supervisor can look at an ongoing chat and send a ‘whisper message’ to the agent that is not customer visible. For example, a supervisor may ‘whisper’ to an agent in order to offer advice or assistance. Set the Supervisor and Chat Transfer Settings:

5. Configure your Deployments

Deployment settings will allow you to specify branding, permitted Domains and set permission for visitors to save the chat transcript. The Deployment code that will be used on your webpage is located here upon Saving.

Upon clicking Save, the following deployment code will generate on the Deployment detail page. You can take the code and paste it into your web page.

This is the end of the basic setup. Once your button is live you can test it out by first logging into your Salesforce and navigating to the service console. Be sure you are set to active in order to get an incoming chat. Once the chat has ended look for the Chat Transcript in your Salesforce. This is where the details of each chat are stored. The Chat Transcripts are customizable and may be summarized in Salesforce reports.

System.LimitException: Too many SOQL queries: 101 – while moving into production

This exception is one of the common governor limits that a salesforce developer experiences. Generally we would get this exception when the code is not written properly . ie. You have a SOQL query with in a for loop.

But many a times while deploying a trigger or class to production i get ths error. I check and double check if there were any SOQL queries within a for loop. But nothing in the class or trigger has the SOQL with in a loop and this is reflected in a different test class other than the code you are moving into production.

This happens because we would not have used the Test.startTest() and Test.stopTest() methods in our test classes. All the DML operations for setting the data for execution of test should be done before the Test.startTest() method and all the actions for testing your code should be between Test.startTest() and Test.stopTest() methods.

What this does is that it gives context to your test class. In other words only the code executed between the Test.startTest() and Test.stopTest() would be considered in the governor limit calculations. If there are no Test.startTest() and Test.stopTest() then all the setup code and actual test code would count towards the limits.

To those looking for Salesforce opportunities…

Never forget this! You create your own luck!

Be aware of the following considerations for trigger context variables:

• trigger.new and trigger.old cannot be used in Apex DML operations.

• You can use an object to change its own field values using trigger.new, but only in before triggers. In all after triggers, trigger.new is not saved, so a run time exception is thrown.

• trigger.old is always read-only.

• You cannot delete trigger.new.

7 Enhancements in the Salesforce Spring ’14 Release.

1. Direct-to-Agent Chat Available

Once you set up your agents with their corresponding skills, you’ll be able to route a chat request to one specific agent, based on skill set and availability. Additionally, a few other related enhancements make this even better: Agent-declined chat requests can be automatically rerouted AND chat requests can now be automatically accepted once assigned to an agent.

2. Launch Flows from Workflow Rules – Pilot

Salesforce’s Take: Spring ’14 introduces a new workflow action called a flow trigger, which launches a flow when the workflow rule criteria are met. A trigger-ready flow is a flow that can be launched from a flow trigger workflow action. Because trigger-ready flows must be able to run in bulk and without user interaction, they can’t contain Step, Screen, or Apex Plug-in elements in any flow version.

To set this up, you’ll need to do the following:

1. Create and activate a trigger-ready flow
2. Create a workflow rule
3. Create a flow trigger workflow action and associated it with the above workflow rule
4. Activate the workflow rule

3. TEXT() Function Picklist Support Expanded

Salesforce’s Take: The TEXT() formula function now converts picklist values to text in approval rules, approval step rules, workflow rules, auto-response rules, escalation rules, assignment rules, and custom buttons and links.

4. Partial Data Sandboxes

5. Mass Assign Permission Sets

Salesforce’s Take: Now you can assign multiple users and revoke multiple user assignments from a permission set.

6. Create Cases from Salesforce Side Panel

Salesforce’s Take: If your users track customer support issues and gripes with cases they create in Salesforce, they can now create them directly from the side panel.

7. Salesforce Console Enhancements – Multi-monitor

Salesforce’s Take: Move portions of a console from your browser to any locations on your screens that help you work best. Pop out primary tabs, custom components, and other console items and drag them to any area on your screens. If pinned lists are set up, place popped out items in a playground to keep track of Salesforce windows when several applications share your screens.

Relationship between Accounts,Contacts In salesforce

Account and contact behaves as master detail in business logics but on UI it is a lookup relationship. Let me explain you a bit more.

You can create a contact without filling account i.e it shows that there is a lookup relationship between account and contact.

If you have created a contact with account and you delete that account then contact will be deleted, this shows that it is in Master-Detail relationship. This is a standard behavior.

So we can say it in both ways, but it documentation it is a lookup relationship.

For more reference you can visit : http://success.salesforce.com/ideaView?c=09a30000000D9y3&id=08730000000JL3KAAW

I hope it is helpful for you

How to integrate SFDC with external webservice?

Salesforce: APEX HTTP callout example, POST and GET
Steps to implement apex HTTP callout:
How to integrate SFDC with external webservice?



Using this you can integrate your SFDC instance with external systems, that can be your SAP, Oracle Apps or any other in-house application which need your sfdc data more or less immediately to process request.

This callout is for Rest webservice:
 
1) External system enabled with REST webservice with JSON/XML response ( we are using Json in this example)
2) Register, our external endpoint URL with SFDC "Remote sites". ( endpoint URL, is the external system URL which will serving your request)

3) Invoking HTTP Callouts using following code:


Following is the sample/example apex class which is making callouts to external system rest webservice. This example also shows you , how Serializeand deSerialize Json. (Object to Json String and vise-verse).

public with sharing class TestHttpCallOut {

String endPoint = 'http://***yousite_app***.com/sfdc';

public void postDataToRemote(String name,String email,Integer age){
   performAction('POST',name,email,age);  
}
public void fetchDataFromRemote(){
   performAction('GET');  
}


 public void performAction(String method,String name,String email,Integer age){
           
             //Prepare http req
             HttpRequest req = new HttpRequest();
             req.setEndpoint(endPoint);
             req.setMethod(method);
           
                Map<String,object> mapEmp = new Map<String,object>();
                mapEmp.put('name',name);
                mapEmp.put('email',email);
                mapEmp.put('age',age);
                String JSONString = JSON.serialize(mapEmp);  
       
           
            req.setBody(JSONString);
           
            Http http = new Http();
            HTTPResponse res = http.send(req);
           
            System.debug(res.getBody());
       
  }
 
public void performAction(String method){

             HttpRequest req = new HttpRequest();
             req.setEndpoint(endPoint);
             req.setMethod(method);
           
            Http http = new Http();
            HTTPResponse res = http.send(req);
            Map<String,String> responseMap =   (Map<String,String>)JSON.deSerialize(res.getBody(),Map<String,String>.class);
             
              System.debug(responseMap);
             
  }
   
 
}

Use folloiwng commented code to execute this example,

/*
//TestHttpCallOut  a = new TestHttpCallOut ();
//a.fetchDataFromRemote();
//a.postDataToRemote('BOB','abc@xyz.com',101);
*/
