Introduction

When a consumer exits a conversation flow to enter an external system (for example, a generic web view form or Apple Pay for making a payment), the Web View API makes it possible for the external system to post data back into the bot runtime.

The Web View API can be used by the external system to:

  • Set session-scoped variables in the bot runtime
  • Post a message to the chat client
  • Invoke a dialog starter to trigger a dialog flow

Don’t use this API to post Personally Identifiable Information (PII) or Payment Card Industry (PCI) data because the data is not masked.

If you have IP restrictions in place, you'll need to do some whitelisting before using this API. For details, see here.

Getting started

Retrieve your domain based on your environment:

Environment Domain
LivePerson Cloud US va.bc-intg.liveperson.net
LivePerson Cloud UK lo.bc-intg.liveperson.net
LivePerson Cloud SY sy.bc-intg.liveperson.net
Amazon Web Services US platformservice.botcentralapi.com
Amazon Web Services UK integration-eu.botcentralapi.com
Amazon Web Services SY integration-ap.botcentralapi.com
Google Cloud Platform PROD cbsrvc-us-p.liveperson.net

Also review the API terms of use.

Requirements

The API requires three fields that the external system must obtain from the conversation:

  • userId: The user ID can be retrieved using the getUserPlatformId function.
  • botId: The bot ID can be retrieved from the bot settings; see the Bot ID field.
  • conversationId: The conversation ID can be retrieved using the getConversationId function.

Request

Use the POST method to set session-scoped variables in the bot runtime.

Method URL
POST https://{domain}/thirdparty-services-0.1/webview

Headers

Name Value Notes
Content-Type application/json  
Authorization The API access key that you need to pass; originally retrieved from the conversation This is an SHA authorization token that is a combination of the conversationId and the botId. It should be generated by creating a sha256 hash:

auth = sha256hex(conversationId + “ || “ + botId)

For example: sha256hex(“abcd || xyz”)

Note the space, two pipe characters, and space after the conversationId.

BODY/POST parameters

Name Description Type/Value Required Notes
botId The bot ID string Required  
conversationId The conversation ID string Required  
userId The consumer's user ID string Required  
message The message to send to the bot runtime string Optional If set, this message is posted to the chat client.

To also trigger a dialog starter, this message must match to a Dialog Starter interaction in one of the bot’s dialogs.

If unset, the Web View service only posts the variables.
contextVariables The key/value pairs that can be passed to the bot platform object:list of strings Optional These key/value pairs can be used in the bot runtime using the Get Web View Variables JavaScript functions.

Example

curl -X POST \
  https://{domain}/thirdparty-services-0.1/webview \
  -H 'Authorization: F8488E6143818BB0364717A91F235F7F7F0FE91C464EC6FAC7ECF0D3393EBBAF' \
  -H 'Content-Type: application/json' \
  -d '{
    "botId": "795bb1534e34fc89050304e6f6827c41c50410d7",
    "conversationId": "a845678d-fe5a-429e-bc46-b25d524b9fa7",
    "message":"webrequest",
    "userId": "b849678d-fe4a-439e-bc46-b25d524b9fa7",
    "contextVariables": [{"name": "PaymentId","value": "534e34fc89050304e6f6827c41c50410d7"}, {"name": "PaymentStatus","value": "PROCESSED"}]}'

Retrieving the Web View variables

Use the Get Web View Variables JavaScript functions to retrieve the variables set via the Web View API from the bot runtime.
