Overview

Fallback is a solution that allows you to attempt delivery across multiple channels based on delivery status (DLR) or timeout, thereby improving the chances of successfully reaching the end users.

The Kaleyra platform's Fallback Invocation API provides a simple REST interface for triggering a Fallback workflow to a specific recipient. Once the request is accepted, the workflow is executed based on the configuration set in the Fallback User Interface, along with any dynamic data supplied during runtime. It uses standard HTTP methods and status codes, making it easy to integrate into your systems.

For businesses planning to implement a multi-channel Fallback strategy:

• You need to complete the Onboarding steps and contact Support team to enable the feature for your account.
• Once a Fallback is published, you can use its associated Workflow ID to trigger the workflow for a specific recipient.
