This section will describe the responses that are expected to be sent by the Send Conversation Events endpoint of the Custom Endpoint service. To ensure the validity of the response, brands can use our Conversation Tester feature. In the case of Structured Content validation, you can also leverage this tool.

Sending Encoded Metadata

The Conversational Cloud Messaging platform provides a new metadata input type (“encodedMetadata”) for passing a base64 encoded metadata on a conversation. The new metadata input type is in addition to the existing conversation metadata input field. Third-party Bot also supports this property and this section will cover the information needed for you to send encoded metadata within your conversations. Before sending encoded metadata you must ensure the following conditions in order to successfully send the data.

  • Common.EncodedMetadata AC feature is ON
  • Content is base64 encoded
  • Metadata size is limited to 5k

Failing to comply with the above validation points will cause the message to be dropped. This feature is only available for messaging conversations, not for chat conversations

Sending Text Message with Encoded Metadata

You can send encodedMetadata with a simple text message an example of such a response can be seen in Figure 4.1. More information on responses expected by Third-Party Bot Connector can be found at API Service Specification

{
  "response": [
    {
      "type": "TEXT",
      "data": {
        "message": "This is a text with encoded metadata",
        "encodedMetadata": "ewoic29tZUluZm8iOiAiSSB3YXMgZW5jb2RlZCIKfQ==",
        "metadata": [{ "type": "ExternalId", "id": "ABCD1234" }]
      }
    }
  ],
  "analytics": {

        "confidenceScore": 0.99
      }
    ]
  }
}

Sending Rich Content (structured content) with Encoded Metadata

You can send encodedMetadata with a structured content message an example of such a response can be seen in Figure 4.2. More information on responses expected by Third-Party Bot Connector can be found at API Service Specification

{
  "response": [
    {
      "type": "STRUCTURED_CONTENT",
      "data": {
        "metadata": [{ "type": "ExternalId", "id": "ABCD1234" }],

          "elements": [
            {
              "type": "button",
              "click": {
                "actions": [
                  { "text": "Recommend Me a movie!", "type": "publishText" }
                ]
              },
              "title": "Recommend Me a movie!"
            }
          ]
        }
      }
    }

        "confidenceScore": 0.99
      }
    ]
  }
}

Sending Pause/Delay Message

It is possible to send an event of type "delay" before regular content events and actions. This specifies the time the bot will wait before displaying the next message. An example of such a response can be seen in Figure 4.3 where one text message is displayed then 5 seconds of delay and after that, a structured content is presented. More information on responses expected by Third-Party Bot Connector can be found at API Service Specification

{
  "response": [
    {
      "type": "TEXT",
      "data": {
        "message": "Please wait while I prepare to give you options!"
      }
    },
    {
      "type": "DELAY",
      "data": {
        "seconds": 4,
        "typing": true
      }
    },
    {
      "type": "STRUCTURED_CONTENT",
      "data": {
        "metadata": [
          {
            "type": "ExternalId",
            "id": "ABCD1234"
          }
        ],
        "structuredContent": {
          "type": "vertical",
          "elements": [
            {
              "type": "button",
              "click": {
                "actions": [
                  {
                    "text": "Recommend me a movie",
                    "type": "publishText"
                  }
                ]
              },
              "title": "Recommend a movie"
            }
          ]
        }
      }
    }
  ],
  "analytics": {
    "intents": [
      {
        "id": "base-delay",
        "description": "Delay Message",

        "description": "Mix Messages",
        "confidenceScore": 0.99
      }
    ]
  }
}

Sending Private Text Message

It is possible to send a private text message from the Live Engage (LE-UI) via the agent workspace. This feature can now be used via Third-Party bots as well. This will allow brands to define private message text within the conversational flow of the bot. These messages are published in the conversation for other Agent/Manger participants. This enables Brands to customize messages giving more insight, summarizing actions taken by the bot, or also advising on the next actions the handover agent should take. Please note private text messages will never be shown to the consumer and will be visible only inside the conversation window of the agent workspace.

Please note If you have not migrated to the new Agent Workspace you will not be able to see the Private message indicator in the conversation window. Nevertheless, private text messages will not be shown to the consumer and only remain visible to Agents and Managers.

An example of such a response can be seen in Figure 4.4. More information on responses expected by Third-Party Bot connector can be found at API Service Specification

{
  "response": [
    {
      "type": "TEXT",
      "data": {
        "message": "I am hidden from the customer",
        "messageAudience": "AGENTS_AND_MANAGERS"
      }
    },
    {
      "type": "TEXT",
      "data": {
        "message": "This is a normal text"
      }
    }
  ],
  "analytics": {
    "intents": [
      {
        "id": "base-all",
        "description": "Mix Messages",
        "confidenceScore": 1
      }
    ]
  }
}

Invoke LivePerson Function

During a conversation, it is possible to trigger a LivePerson Function that is deployed to the LivePerson Functions (Function as a Service) platform. We provide a way to run custom logic with a bot. You need to ensure that the LivePerson Function is deployed and running. Furthermore, the user can provide a payload as well that will be sent to the LivePerson function while invocation. The invoke response is considered an action response. An example of such a response can be seen in Figure 4.5.

Please note we only support ONE ACTION per response

{
  "response": [
    {
      "type": "TEXT",
      "data": { "message": "I will invoke a function after this text" }
    },
    {
      "type": "ACTION",
      "data": {
        "name": "INVOKE_FUNCTION",
        "parameters": {
          "lambdaUuid": "4f9c233a-e7e6-4af3-b680-59ba20ab8962",
          "payload": { "message": "I am invocation function payload" }
        }
      }
    }
  ],
  "analytics": {
    "intents": [
      {
        "id": "base-invoke",
        "description": "Generic invocation Intent",
        "confidenceScore": 0.95
      }
    ]
  }
}

Figure 4.5 Showing an example response of invoke LivePerson function

The bot does not escalate on a failed invocation by default. To enable this, set the additional parameter failOnError to true. An example of such a response can be seen in Figure 4.6

{
  "response": [
    {
      "type": "TEXT",
      "data": {
        "message": "I will invoke a function after this text that cause escalation on failure"
      }
    },
    {
      "type": "ACTION",
      "data": {
        "name": "INVOKE_FUNCTION",
        "parameters": {
          "lambdaUuid": "4f9c233a-e7e6-4af3-b680-59ba20ab8962",
          "payload": { "message": "I am invocation function payload" },
          "failOnError": true
        }
      }
    }
  ],
  "analytics": {
    "intents": [
      {
        "id": "base-invoke",
        "description": "Generic invocation Intent",
        "confidenceScore": 0.95
      }
    ]
  }
}

Sending SIGNALED events (Messaging Only)

This Feature requires UMS 4.9

To send a signal to the channel not visible inside the normal conversation a bot can send the following event. Channels need to implement custom logic and listen on chat state events in order to react to it.

{
  "response": [
    {
      "type": "ACTION",
      "data": {
        "name": "SIGNAL",
        "parameters": {
          "payload": {
            "test": "value"
          }
        }
      }
    }
  ],
  "analytics": {
    "intents": [
      {
        "id": "signal-request",
        "description": "customer side requested a signal",
        "confidenceScore": 1
      }
    ]
  }
}

Engagement attributes (SDES) as context

Third-Party bots allow the collection of engagement attributes (more information can be found here) if Engagement Attributes option is checked in the Conversation Type step as shown in Figure 2.4.

Figure 2.4 Conversation Type step in creation/modification of bot configuration.

These attributes are only collected at the start of a conversation. we send those engagement attributes when the Third-Party Bot connector calls the Create Conversation endpoint of the Custom Endpoint service.

Third-Party bots leverage the LivePerson Visit Information API to collect the engagement attributes, Further information on Visit Information API can be found here. Moreover, Engagement attributes are not updated throughout the life cycle of a conversation and are only passed along with each message request.

Receiving Rich Content Response (Messaging Only)

Third-Party Bots allow LivePerson's Rich Messaging channel capabilities not only to be received as a response from the vendor but also, to allow Rich Messages(Structured Content) to be sent back to the vendor based on specific user interactions/responses (For example user sharing their location on WhatsApp). Please note these capabilities are sometimes limited by the channels in which the conversation is happening. For the list of Rich Messaging capabilities for each channel, browse or search the table on the Knowledge Center.

An example of a request body of Rich Content Event (of type map) sent by Third-Party Bot container to Custom Endpoint service can be seen in Figure 4.7. More information on the request expected by Third-Party Bot Connector can be found at API Service Specification.

{
  "type": "RICH_CONTENT",
  "source": "CONSUMER",
  "data": {
    "content": {
      "type": "vertical",
      "elements": [
        {
          "type": "map",
          "la": 49.43180847167969,
          "lo": 7.755561351776123,
          "alt": "49.43180847167969, 7.755561351776123"
        }
      ]
    }
  },
  "context": {
    // here comes context information
  }
}

Figure 4.7 An example of Rich Content Event request sent by Third-Party Bot connector to Custom Endpoint service

Some important things to notice here are

  • The request body contains type which identifies that the content type is RICH_CONTENT
  • The actual body of the Rich Content Event can be accessed via data.content property

A demo of our WhatsApp map example with the response from an example custom endpoint service can be seen in Figure 4.8:

Figure 4.8 A Demo of sending raw response back from Custom Endpoint Service on receiving Rich Content Event

Receiving Last consumer message (Messaging Only)

When an ongoing conversation gets transferred to a bot connected via the Third-Party Bot connector, the connector forwards the last consumer message to the AI vendor as part of the the welcome event. This allows the bot to react to the last consumer message instead of instantiating a new conversation.

In the Custom Endpoint service, the last consumer message is passed via the property lastConsumerMessage that is sent with context information as part of lpEvent data. An example of the request body containing the WelcomeEvent is provided below:

{
  "type": "START",
  "source": "CONVERSATION",
  "data": {},
  "context": {
    "lpEvent": {
      "type": "ContentEvent",
      "contentType": "welcome",
      "lastConsumerMessage": "I need to return my order",
    }
  }
}

Send Secure Forms (PCI)

Secure forms are configured by LivePerson. To enable this feature, please contact LivePerson customer support or your account team. Your LivePerson account team will work with you make the necessary adjustments to your account settings and configurations. For additional information regarding secure forms: Knowledge Center

To give agents the permission to read secure forms sent by a bot, please contact LivePerson customer support to enable the site setting: messaging.display.secure.form.sent.by.bots

Bots are able to send a secure form to a conversation and transfer the customer after submission. The transferred conversation is then visible by an eligible agent, that can read and process the submitted form data.

To enable this feature for Custom Endpoint, you need to create a new Intent with a matching utterance and a customisable payload response to it. The payload needs to send a SEND_SECURE_FORM action including the unique formId of the form,that should be provided from LivePerson after the creation of one secure form, and the title of the form.

{
    "type": "ACTION",
    "params": {
        "action": "SEND_SECURE_FORM",
        "data": {
            "formId": 4510014332,
            "title": "Form with only mandatory fields"
        }
    }
}
{
  "response": [
    {
      "type": "ACTION",
      "data": {
        "name": "SEND_SECURE_FORM",
        "parameters": {      
          "formId": 4510014332,
          "title": "Form with only mandatory fields" 
          }
      }
    }
  ],
  "analytics": {
    "intents": [
      {
        "id": "secure-form",
        "description": "Secure Form",
        "confidenceScore": 1
      }
    ]
  }
}

To transfer the conversation after submission to an eligible user that can process the secure forms, you need to create a new intent listening on the utterance FORM-SUBMISSION-INTENT that transfers the conversation using a basic transfer event.

Receiving signaled events (Messaging Only)

This Feature requires UMS 4.9

If SIGNALED events are enabled in the Conversation Type settings the bot will be able to receive this kind of chat state events.

{
  "type": "SIGNAL",
  "source": "CONSUMER",
  "data": {
    "content": "" // the metadata payload string
  },
  "context": {
    // here comes context information
  }
}
