このタスクについて

注:

If you’re using existing code, verify that you update the script to show v=3.1. For example:

<script src="https://example.service-now.com/scripts/sn_csm_ec.js?v=3.1"></script>
<script>
SN_CSM_EC.init({
      moduleID: "https://example.service-now.com/#aeff0547dd393010f87734cef087e2ba",
      loadFeature: SN_CSM_EC.loadEMFeature()
});
</script>

手順

1. Navigate to Engagement Messenger > Modules.
2. In the Configure Engagement Messenger Module, open the Implement tab.
3. Copy the code from the Embed code section.
4. In a text editor, open the HTML file of the web page on your website where you integrate Engagement Messenger.
5. Paste the code that you copied before the closing body tag.
6. Define the feature context and specify the variables for the feature.
   Use the following format to define a feature context:

   { 
   	feature: "<feature_name>", 
   	openOnLoad: <true/false>, 
   	params: { 
   		"<param_name>": "<param_value>",
   		"<param_name>": "<param_value> 
   	} 
   }

   In the format, specify the feature variables.

   feature

   The feature name. For more information, see Feature context parameters supported in Engagement Messenger .

   openOnLoad

   Include this option and set it to true only if you want Engagement Messenger to open automatically. The default setting for this option is for Engagement Messenger not to open automatically.

   <param_name>": "<param_value>

   Name and value of a parameter associated with the feature. For more information, see Feature context parameters supported in Engagement Messenger.

7. Create a custom wrapper function to pass the feature context to the SN_CSM_EC.init function of the embed code.
   For example, the following code uses the chatFeatureContext() custom wrapper function for the chat feature context.

   
   function chatFeatureContext(){ 
   	return { 
   			feature: "CHAT",
   			openOnLoad: false,
   			params: { 
   				"topic_id": "8708db281bd5b81080df6247b04bcb79",
   				"language": "fr"		
   				} 
   		  } 
   }

8. Replace the SN_CSM_EC.loadEMFeature() function with a custom wrapper function that you created in step 7.
   For example, in the following code, the chatFeatureContext() wrapper function is passed as the value of the loadFeature attribute.

   SN_CSM_EC.init({ 
   		moduleID: "https://example.service-now.com/#<module_id>", 
   		loadFeature: chatFeatureContext()
   }); 
   

9. Save the file.
10. オプション: Verify that the designated feature launches.
    1. Open the website in which you embedded Engagement Messenger.
    2. Select the launcher icon.
    3. Verify that Engagement Messenger launches feature you configured in the embed code.

タスクの結果

The feature you specified in the embed code is launched by default when Engagement Messenger is opened in the website in which it’s embedded.

例

The following code initiates the chat feature by default. It also shows how to trigger a Virtual Agent topic by default when chat is loaded by passing the system identifier (sys_id) of the topic. You can also specify a language to initiate chat in that language.

<script src="https://example.servicenow.com/scripts/sn_csm_ec.js?v=3.1"></script>
<script>
function chatFeatureContext(){ 
	return { 
			feature: "CHAT",
			openOnLoad: false,
			params: { 
				"topic_id": "8708db281bd5b81080df6247b04bcb79",
				"language": "fr"		
				} 
		  } 
}

SN_CSM_EC.init({
	moduleID: "https://example.service-now.com/#d27c94d6db403810a2a6a0ced39619da",
	loadFeature: chatFeatureContext()
