Understanding the Power of vapi.ai and Zapier Together

Before diving into the setup process, let's understand why this integration matters and what it can do for your business.

What is vapi.ai?

Vapi.ai is a cutting-edge conversational AI platform that enables businesses to create sophisticated voice experiences.

It enables you to create "Zaps"—automated workflows that move information between your apps according to rules you define. The beauty of Zapier lies in its no-code interface, making automation accessible to anyone regardless of technical background.

Step 3: Setting Up vapi.ai in Zapier

Now, switch to your Zapier account to set up the connection:

  1. Log in to Zapier Navigate to zapier.com and log in to your account.

  2. Create a New Zap Click the "Create Zap" button to start building your automation workflow.

  3. Select vapi.ai as a Trigger or Action

    • For actions (tasks you want to perform in vapi.ai), search for and select "vapi.ai" as your action app

  4. Connect Your vapi.ai Account

    • Click "Connect a new account"
    • Enter the API key you generated in Step 2
    • Name your account connection (e.g., "My Vapi Account")
    • Click "Yes, Continue" to finalize the connection

Step 4: Configuring Your First Zap with vapi.ai Triggers

Let's set up a simple automation that triggers when a specific event occurs in vapi.ai:

  1. Select a vapi.ai Trigger Event Common trigger options include:

    • New Conversation Started
    • Conversation Completed
    • Specific Intent Detected
    • Form Field Completed
    • Custom Webhook Event

  2. Configure the Trigger Select the specific voice agent and any other parameters required for your chosen trigger type.

  3. Test the Trigger Zapier will attempt to pull a recent event from your vapi.ai account to confirm the connection works properly.

Step 5: Adding Actions to Your Workflow

Now that your trigger is set up, you need to define what happens when it fires:

  1. Add an Action Click "+" followed by "Action" to add an action step to your Zap.

  2. Select an App and Action Choose from thousands of apps like Google Sheets, Slack, HubSpot, or Salesforce, and select the specific action you want to perform.

  3. Map Data from vapi.ai to Your Action Use the dropdown fields to map data from your vapi.ai trigger to the corresponding fields in your action. For example, you might map:

    • Caller's phone number to a contact field
    • Intent detected to a notes field
    • Conversation transcript to a message body
    • Custom variables collected during the call to specific fields

  4. Test Your Action Verify that the action works as expected with sample data from your trigger.

Step 6: Advanced Configuration and Multiple Steps

For more sophisticated workflows:

  1. Add Filters Click the "+" between your trigger and action, then select "Filter" to add conditions that determine when your Zap should run. For example, only proceed if the caller expressed interest in a specific product.

  2. Add Multiple Actions Continue adding actions to create multi-step workflows. For instance:

    • First action: Create a new lead in your CRM
    • Second action: Add the lead to an email nurture sequence
    • Third action: Notify your sales team via Slack
    • Fourth action: Schedule a follow-up task in your task management system

  3. Use Paths for Conditional Logic For paid Zapier plans, use Paths to create different branches based on conditions from your vapi.ai data.

Step 7: Turning On Your Zap

Once you're satisfied with your workflow:

  1. Name your Zap something descriptive that indicates its purpose
  2. Turn on the Zap by clicking the toggle switch at the bottom of the editor
  3. Monitor the Zap's activity in your Zapier dashboard to ensure it runs as expected
