Actions managed by redirect command

Introduction

Certain actions can be performed by aura-bridge when a specific command is received. Currently, only the redirect command is implemented in the plugins that manage messages from aura-groot:

• directline-whatsapp-processor plugin
• directline-rcs-processor plugin

Redirect command

The redirect command allows sending a message to aura-groot when a message with this command is received by aura-bridge from aura-groot. For example, if you want to launch an intent after login in aura-groot. In this case, aura-bot needs to receive the new requested intent from outside to relaunch and complete the authentication flow.

The format of an action message is the following:

• In channelData V3:

{
  "type":"message",
  "channelData":{
    "actions":[
      {
        "target":"bridge",
        "name":"REDIRECT.COMMAND",
        "params":{
          "auraCommand":{
            "type":"suggestion",
            "value":{
              "intent":"intent.common.greetings"
            }
          }
        }
      }
    ]
  },
  "inputHint":"ignoringInput"
}

• In channelData V1:

{
    "type": "message",
    "channelData": {
        "customData": {
            "type": "redirect",
            "action": "REDIRECT.COMMAND",
            "data": {
                "auraCommand": {
                    "type": "suggestion",
                    "value": {
                        "intent": "intent.common.greetings"
                    }
                }
            }
        },
    },
    "inputHint": "ignoringInput"
}

In this example, if aura-bridge receives this message, it will send an auraCommand with the intent intent.common.greetings to aura-groot.

Redirect command in directline-whatsapp-processor plugin

The directline-whatsapp-processor plugin can behave in different ways depending on the message containing the REDIRECT.COMMAND action:

• aura-groot message contains text in the text field: In this scenario, in addition to sending the message to the bot with the REDIRECT.COMMAND information, a message will be sent to WhatsApp with that text.

graph LR
    A(aura-groot) -->|Redirect message| B(Bridge)
    B -->|Whatsapp user message| W[Whatsapp]
    B -->|Redirect message| A

• aura-groot message does not contains text (empty) in the text field:
  In this scenario, only one message will be sent to the bot with the REDIRECT.COMMAND information. No message will be sent to the WhatsApp user.

graph LR
    A(aura-groot) -->|Redirect message with empty text| B(Bridge)
    B -->|Redirect message| A

The same process is followed in the directline-rcs-processor plugin.
