This project is a reference implementation of a skeleton adapter to receive and deliver messages with Medallia Conversations. Developed and maintained as a standalone app in order to leverage the Message Connector API functionality of Medallia Conversations, it is an example of the red/middle box in the graphic below.

This project may be run either on a classic host (non-containerized) or a Docker container. The two subsections below describe the steps needed for each.

On a host machine with hostname/IP of <ADAPTER_HOST>, run the following sequence of commands:

1. git clone <where ever we host the skeleton>
2. Set environment variable:
   • export CONVO_WEBHOOK_URL=<MEDALLIA_CONVERSATION_HOST>
   • export SHARED_SECRET=<32_CHARACTER_STRING>
   • export ACCESS_TOKEN=<STRING that is configured in the channel>
3. npm install
4. npm start

This will start a service on port 1338.

On the Docker host system, run the following sequence of commands:

1. Edit Dockerfile:
   • Change <32_CHARACTER_STRING> to a 32 character string.
   • Change <MEDALLIA_CONVERSATION_HOST> to your Medallia Conversations host.
2. docker build -t skeleton .
3. docker run -p 1338:1338 -t skeleton

This will start a service on port 1338.

1. Log in to your Medallia Conversations instance.
2. Under Channels, create a Custom channel.
   1. Set Custom send message URL to http://<ADAPTER_HOST>:1338/custom/me/messages.
   2. Page ID A unique identification in the conversations system for your adapter.
      • We are using 1234 in this example
   3. App ID 1234
   4. Secret The string must be 32 characters long. This is used to generate signature of the body to send it to Medallia Conversations
      • This example is the SHARED_SECRET configured in Conversations <32_CHARACTER_STRING> above.
   5. Token A string to verify send message. You must configure accordingly and provide as env variable ACCESS_TOKEN.
3. Create a conversation on your instance.
   1. Add keyword hello
   2. Create a dialog type statement with Hello World! in the What do you want to say?.
   3. Create another dialog with type Open Question with How is your day? in the What do you want to say?.
   4. Click save.

Call the running adapter:

curl -X POST \
  http://<ADAPTER_HOST>:1338/messages/ \
  -H 'Content-Type: application/json' \
  -H 'Cache-Control: no-cache' \
  -d '{
    "consumer_id": "1234user5678",
    "page_id": "1234",
    "text": "hello"
  }'

The adapter should return something like the following:

Receiving post to skeleton webhook: {"consumer_id":"1234user5678","page_id":"1234","text":"hello"}
sending text message to Convo: {"body":{"object":"page","entry":[{"id":"1234","time":1558473634322,"messaging":[{"sender":{"id":"1234user5678"},"recipient":{"id":"1234"},"timestamp":1558473634322,"message":{"mid":1558473634322,"text":"hello"}}]}]},"url":"https://<MEDALLIA_CONVERSATION_HOST>/cg/mc/custom/<CHANNEL_GUID>"}
response from sendText: OK

/me/messages called with: {"body":{"recipient":{"id":"1234user5678"},"message":{"text":"Hello World!"},"notification_type":"REGULAR"},"access_token":"<env.ACCESS_TOKEN>"}

The hello text will trigger the conversation configured in Configure Conversations because of the Add keyword step.

This sample adapter will respond with something similar to

{
	"recipient_id": "1234user5678", // consumer_id in the original curl request
	"message_id": "1234user5678.1558473039324" // A generated id with consumer_id + timestamp
}

We highly recommend sending a delivery receipt:

curl -X POST \
  http://<ADAPTER_HOST>:1338/deliveries/ \
  -H 'Content-Type: application/json' \
  -H 'Cache-Control: no-cache' \
  -d '{
    "consumer_id": "1234user5678",
    "page_id": "1234",
    "mid": "1234user5678.1558473039324"
  }'

The delivery receipt will trigger Conversations to send the next dialog. In this case, the open question 'How is your day?'. By default, Conversations will send the next question after 30 seconds.

The adapter service should log similar to the following:

/me/messages called with: {"body":{"recipient":{"id":"1234user5678"},"message":{"quick_replies":[{"title":"Done","content_type":"text","payload":"Done"}],"text":"How is your day?"}},"access_token":"<env.ACCESS_TOKEN>"}

Respond to the question How is your day? like so:

curl -X POST \
  http://<ADAPTER_HOST>:1338/messages/ \
  -H 'Content-Type: application/json' \
  -H 'cache-control: no-cache' \
  -d '{
        "consumer_id": "1234user5678",
        "page_id": "1234",
        "text": "Great!  Thank you!"
}'

You may finish the conversation by responding with done in place of Great! Thank you! above.

Congratulations!
