As of the writing of this document, Flex does not natively support transferring of non-voice tasks. It is on the roadmap and when its released you should migrate to that solution.

This plugin requires Flex v1.9 and above.

This plugin will add a transfer button near the End Chat button. Clicking this button will open the default worker/queue directory. Upon selecting a Queue, this plugin will initiate a blind transfer of the chat task to the specified queue.

Because Flex does not yet support transfering Chat/SMS tasks natively, this plugin works by creating a new task and routing it through your workflow as normal. The original task is automatically completed by the provided function, and all subsequent "transfer" tasks are linked to the original task to be compatible with WFO reporting.

It is up to you to implement the necessary Task Router routing rules to send the task to the specified queue. To aid you in this, two new attributes will be added to your tasks: ignoreAgent and requiredQueue.

The selected queue sid will be populated in the requiredQueue attribute, and the agent that initiated the transfer will be added to the ignoreAgent attribute - this will aid you in ensuring that the last agent to transfer the task will not receive the transfer they initiated.

There is a single function Located in src/functions that you are expected to implement in the Twilio Functions Runtime, or to replicate in your own backend application.

The provided functions in their current state are looking for your TaskRouter Workspace Sid in the TWILIO_WORKSPACE_SID variable. Please ensure this is set in your Twilio Function configuration.

This plugin uses a Twilio function to actually perform the "transfer" of the chat task. If you use the Twilio Functions Runtime you'll want to validate that the incoming requests to your function are actually coming from a Flex front-end.

This plugin will send the Flex user's token along with the task information to transfer, upon validating the token, it will intiate the transfer. This plugin expects that you've configured your Twilio Functions Runtime dependencies and added the twilio-flex-token-validator package.

Make sure you have Node.js as well as npm installed.

Afterwards install the dependencies by running npm install:

cd plugin-chat-transfer

# If you use npm
npm install

In order to develop locally, you can use the Webpack Dev Server by running:

npm start

This will automatically start up the Webpack Dev Server and open the browser for you. Your app will run on http://localhost:8080. If you want to change that you can do this by setting the PORT environment variable:

PORT=3000 npm start

When you make changes to your code, the browser window will be automatically refreshed.

Once you are happy with your plugin, you have to bundle it, in order to deply it to Twilio Flex.

Run the following command to start the bundling:

npm run build

Afterwards, you'll find in your project a build/ folder that contains a file with the name of your plugin project. For example plugin-example.js. Take this file and upload it into the Assets part of your Twilio Runtime.

Note: Common packages like React, ReactDOM, Redux and ReactRedux are not bundled with the build because they are treated as external dependencies so the plugin will depend on Flex which would provide them globally.
