A Fallback flow must include at least two channels. As of now, Kaleyra platform supports SMS and WhatsApp channels. When a Fallback is triggered using API, the message will attempt delivery through the first channel.

To configure the first channel, perform the following steps:

  1. Follow step 1 to step 3 of the Create New Fallback Flow page.
    The New Fallback Flow page appears.
  1. On the First Channel section, click Configure.
    The Configure First Channel pane appears on the right side of the page.
  1. On the Select Channel, click the arrow next to Choose Channel, and a list of supported channels appears. Select one of the channels to configure the first channel from the following list:

  • SMS - Select SMS as the first channel and enter the following details:

    1. On the From, click the arrow next to the Select field, and a list of approved Sender IDs appears. Select the number to send the SMS.
    2. On the Template, click the arrow next to the Select field, and a list of approved templates appears. Select the template using which you want to send the SMS. The message preview will appear when a template is selected. For more information on how to create a template, see Create an SMS Template.
    3. In the Delay field, enter the time interval in seconds between the two channels. If no DLR or if a failed DLR is received within this time interval, the Fallback flow will send the message on the second channel. The minimum delay time is 5 seconds (five seconds) and the maximum delay time is 900 seconds (15 minutes).
