Salesforce Live Agent allows you to connect with customers in real time through a web-based, text-only live chat. To initiate text-only live chat, a pre-chat form is a useful feature.
A pre-chat form is used to gather basic information from customers, like name, email, phone number, and reason for contacting the agent — all of which will help in redirecting the customer to the right agent in minimal time. To gather more information, if required, you can customize the pre-chat form using a VisualForce page.
You can create custom fields in the Standard Live Agent object, which can then be mapped using the pre-chat form and will be visible to the agent on the hover pop-up during the incoming chat. The format to map custom fields is: name=”liveagent.pre chat:.
If you don’t want to show any custom detail on the page, you can hide it using this statement:
<input type=”hidden” name=”liveagent.prechat.save:customDetail” value=”Custom_Field__c”/>
Once you have completed the setup, you will need to map those details to Salesforce. You can create only single mapping for each object. In each mapping, you need to specify the Salesforce object’s field name and custom detail name, and you can separate each pair with a semicolon.
This is how you can show a textbox for input email:
<input type=”text” name=”liveagent.prechat:contactFirstName” />
<input type=”text” name=”liveagent.prechat:contactLastName” />
<input type=”text” name=”liveagent.prechat:contactEmail” />
<input type=”hidden” name=”liveagent.prechat:SessionId” id=”prechat_field_session_id” value=”” />
This is how you can map this detail to Salesforce:
<input type=”hidden” name=”liveagent.prechat.findorcreate.map:Contact” value=”FirstName,contactFirstName;LastName,contactLastName;Email,contactEmail;Session_Id__c,SessionId” />
The next step is to determine whether you want to perform a search on the existing records in Salesforce. You can do this by using doFind. You can also specify if you want an exact match or a partial match for the search string.
This will search on Contact records using input Email for exact match on Contact records.
<input type=”hidden” name=”liveagent.prechat.findorcreate.map.doFind:Contact” value=”Email,true;” />
<input type=”hidden” name=”liveagent.prechat.findorcreate.map.isExactMatch:Contact” value=”Email,true;” />
To use another object, you need to specify one more mapping similarly.
If a matched record is found, Salesforce will open its detail page in a new subtab. If more than one record matches, it will display a list of those matched records. If you want to create a new field (in case there is no match found) then you need to use doCreate input.
<input type=”hidden” name=”liveagent.prechat.findorcreate.map.doCreate:Contact” value=”FirstName,true;LastName,true;Email,true;Session_Id__c,true” />
The fields specified in the value attribute will be mapped from the pre-chat form to a new Contact record. If you don’t specify doFind, it will always create a new Contact record. So if you want to search, use doFind, and if you want to create a new record, use doCreate. If you want to search and create, use both.
If you want to show a newly created/searched record you can also control that using showOnCreate.
<input type=”hidden” name=”liveagent.prechat.findorcreate.showOnCreate:Contact” value=”true” />
The Live Chat Transcript Object is related to the Contact field via a standard lookup field, so if you want to relate the live chat transcript to the Contact field, you can use saveToTranscript to populate that lookup field on the chat transcript.
<input type=”hidden” name=”liveagent.prechat.findorcreate.saveToTranscript:Contact” value=”Contact” />
