Create a custom workflow

Transform voice AI conversations into instant communication actions by connecting Vapi triggers with Twilio's messaging and calling capabilities through Make. Automatically respond to customer interactions in real-time—when Vapi detects conversation events, Twilio springs into action, sending SMS messages or initiating calls without manual intervention, creating an automated communication workflow.

Create a custom workflow

Every automation starts with a trigger and an action. Select one from each app to generate a workflow tailored to your needs.

Triggers and actions

Connect Twilio as a trigger and Vapi as an action through Make's integration platform to enable powerful automation. When Twilio detects voice interactions or conversation events, it automatically triggers workflows that execute actions in Vapi's communication infrastructure. Set up Twilio triggers to monitor call completions, conversation outcomes, or specific voice AI events, which then activate Vapi actions to send SMS messages, initiate voice calls, or manage messaging services in response. This trigger-action integration enables you to automatically respond to Twilio's conversational AI events by executing corresponding communication tasks through Vapi, eliminating manual intervention and ensuring real-time responses to customer interactions.
