  2. Change the endpoint in the http in node to your liking.
    In the above example, it is /twilio/message.

  3. Click on Done and Deploy the Experience Designer flow.

...

  1. Navigate to https://console.twilio.com/

  2. From the Side navigation bar, select Phone Numbers > Manage > Active Numbers and click on the phone number to go to the configuration page.

  3. On the configuration page, select the “Configure“ tab and scroll down to the Messaging section.


    Add the webhook web hook (URL endpoint) you created in the Experience Designer.
    In this example, it is https://sandbox15.orbita.cloud:8443/oeapi/twilio/message

...

  1. Do not use special characters in the messages.

  2. If the message is large (i.e; greater than 140 characters), split the message into segments and use multiple Twilio nodes to send the segments with a delay.

  3. The maximum number of characters allowed in one segment is 140. If you use multiple segments, then you should restrict the maximum number of characters used in each segment to 134 as 6 characters will be utilized to link the segments together.
