Automate your Vapi voice workflows

Describe a call workflow in plain English and Twin builds an agent that triggers Vapi calls, processes transcripts, and routes outcomes—without manual copying between tools.

What you can do with Vapi

Real Vapi workflows the Twin community runs every day, ready for you to clone.

  • Trigger outbound calls via Vapi

    Initiate calls using a specific Vapi assistant and phone number ID, passing call targets from a spreadsheet or CRM row.

    Explore
  • Monitor and summarize call transcripts

    Pull Vapi call transcripts on a schedule, group them by campaign, and surface common objections and outcomes each day.

    Explore
  • Score and analyze call quality

    Read Vapi call logs and apply scoring rules to flag low-quality calls, then write scores to a linked Google Sheet for review.

    Explore
  • Recover missed calls automatically

    Detect unanswered Vapi calls and re-queue them for follow-up via Twilio, keeping lead contact attempts current without manual checks.

    Explore
  • Edit and manage Vapi assistants

    Update assistant configurations—prompts, voice settings, webhooks—through the Vapi API without opening the dashboard each time.

    Explore
  • Run scheduled prospecting call sequences

    Pull leads from Google Sheets, fire Vapi calls on a defined schedule, and log outcomes back to the same sheet after each call completes.

How it works

Three steps from idea to a running Vapi agent.

  1. 1

    Connect via OAuth

    Sign in to Vapi once. Twin securely manages the connection and handles token refreshes for you.

  2. 2

    Describe the workflow

    Tell Twin in plain English what you want done in Vapi. The agent figures out the API calls itself.

  3. 3

    Twin builds and runs

    Twin assembles the agent, runs it on demand or on a schedule, and adapts when Vapi responds in unexpected ways.

Why Twin for Vapi

What makes Twin a better fit than a generic automation tool.

No manual copy-paste between tools

Vapi produces call data—transcripts, outcomes, logs—that teams typically copy by hand into spreadsheets or CRMs. Twin reads that data via the Vapi API and writes it directly to the destination, so nothing goes stale waiting for a human to move it.

Repeatable workflows, not one-off scripts

Users described needing a reliable way to turn Vapi activity into something that runs the same way every time. Twin agents encode that logic once and execute it on demand or on a schedule, without re-prompting or manual intervention.

Handles both API and browser steps

When structured Vapi API access covers the task, Twin uses it. When a workflow requires navigating dashboard pages or combining Vapi with Twilio and Sheets in the same run, Twin bridges those steps without requiring separate automations.
