Integrating Orbita with Twilio

If you configure the node to make a phone call, provide a TwiML URL that is publicly accessible. You can add the receiving phone number in the To field, in the Twilio node, so that Twilio will send the text message(s) or make a phone call. If the number is left blank, set it to use you set the msg.topic property in the function node connected to the Twilio node, the To field should be left blank.

Setting credentials

There are two options in the Credentials drop-down.

...

• Use global credentials. Contact orbitasupport@orbita.ai to get details on the environmental variables used to configure global credentials.

• Use local credentials. Use this option to give details of your Twilio account in the node. The recipient(s) will receive messages/phone calls from your Twilio phone number.

    See, https://www.twilio.com/console/voice/twiml/overview to learn more about the URL.

  • Name. Name of the node.

Example flow

The following flow shows how to integrate Twilio with Experience Designer.

In the example, when a valid user triggers the help intent, Twilio reads TwiML instructions at that URL. In the function node, the TwiML is already instructed to respond in an automated voice “Please leave a message after the tone” and start the recording for 20 seconds.

...

Two different flows are given in the above example. The first flow creates an endpoint URL that can be used in the Twilio node. The second flow triggers a call when an authenticated user says “help”.

http in node

Creates an http end-point for creating web services.

• Method. Set is set to GET.

• URL. Enter the XML file that will be is created.

  

Function node

The following code is usable used with parameters like msg.payload, statusCode, and msg.header. Push the XML code in msg.payload for this example. This XML code sends a short message and record records the caller’s caller's voice post message.

msg.payload='<?xml version="1.0" encoding="UTF-8"?><Response><Say voice="woman">Please leave a message after the tone.</Say><Record maxLength="20" /></Response>';
msg.statusCode=200;
msg.headers = {"content-type": "application/xml"};
return msg; 

...

http response node

Sends responses back to requests that were received from the HTTP input node.

Intent Request node

Triggers the flow when help is called by the user.

Function node

Checks whether the user is an authenticated user.

Say node
