This integration lets you build custom automations to make outbound calls, handle inbound calls, and sync call data with thousands of apps using Zapier’s triggers and actions.
Zapier is a powerful solution for building no-code automations with Synthflow AI. Connect your AI agents to CRMs, forms, databases, and more to automate voice interactions without writing any code.
Create a Zapier account and then create workflows using our Zapier integration. You can find Synthflow AI in Zapier’s app directory or create a new Zap directly.
Zapier offers a free tier with limited tasks per month, after which you’re charged based on usage. You can create workflows with apps such as Google Sheets, HubSpot, Salesforce, Typeform, Gmail, Slack, Airtable, and thousands more.
Before building workflows, connect your Synthflow account to Zapier. In the Zap editor, select Synthflow AI and authenticate using your API key.
To find or generate your API key, navigate to Integrations → API Keys in your Synthflow dashboard.
Our Zapier integration can be combined with other app triggers or with Zapier’s default triggers to build powerful voice automation workflows. For instance, you can set up a Zapier workflow that makes an AI call whenever a new lead is added to your CRM, or when a form is submitted on your website.
If Synthflow is the start of your Zap, the following events can be used as triggers for downstream actions in other applications:
You can take the following actions in Synthflow AI in response to a trigger you configure in Zapier:
If you’re not seeing full functionality, you may be running an old version of the Zapier integration. Update the version you’re using in a Zap from the status pane in Zapier’s editor.
You can view and edit your Zaps directly from the Synthflow dashboard without leaving the platform.
To access your Zaps:
Your most recent Zaps associated with this agent will appear here, allowing you to quickly manage your automations alongside your agent configuration.

This tutorial demonstrates how to capture call transcripts from an inbound agent and automatically save them to Google Sheets. You can customize this workflow to collect any call data and send it to thousands of other applications.
Before starting, you’ll need:
In Zapier, create a new Zap, click on the first node, search for Synthflow AI and select the Phone Call Completed trigger. This will activate the Zap whenever a call finishes.

Enter your agent’s unique ID. You can find this in your Synthflow dashboard by navigating to your agent’s settings.

Test your trigger to pull in data from the most recent call and review the available call data. You can collect information like phone number, transcript, call duration, and much more.

Now that your trigger is set up, configure the action to send call data to Google Sheets. This example creates a new spreadsheet row with information from each completed call.
Click on the action step and search for Google Sheets. Then, select the Create Spreadsheet Row as the action event and connect your Google account.

Once your tests are successful, turn on your Zap. Every completed call will now automatically add a row to your spreadsheet with the call details.
This tutorial demonstrates how to automatically trigger outbound calls using data from a spreadsheet or any other app. When new data is added or updated, Synthflow will automatically place a call with your AI agent.
Before starting, you’ll need:
In this example, we’ll use Google Sheets as the trigger, but you can use any app that provides contact data such as CRMs, forms, or databases.
Create a new Zap and select Google Sheets as your trigger app. Choose New or Updated Spreadsheet Row as the trigger event.
Now configure the action that will place outbound calls based on your trigger data.
Click on the action step, search for Synthflow AI, select the Create Call action, and connect your Synthflow account.

Configure the call action:
Click the + button next to each field to insert data from the previous step.

Once your test is successful, turn on your Zap. Every time a new row is added or updated in your spreadsheet, Synthflow will automatically place a call with your AI agent to that phone number.
Yes. You can pass pre-call variables from Zapier into your Synthflow AI calls. These variables can be referenced in your agent’s prompts and actions to personalize each conversation.
Use the Phone Call Completed trigger to capture call data and outcomes. You can then route this information to other apps based on call results, extracted information, or agent evaluations.
Yes, you can use Zapier’s looping features or our batch call action to process lists of contacts. Connect a spreadsheet or database to trigger multiple calls in sequence.
Failed calls will still be tracked in your workflow. Check all the possible call statuses. You can set up automatic retries or notifications to your team when calls don’t complete successfully.
Calls made through Zapier are billed according to your Synthflow AI plan, just like calls made through the dashboard or API. Zapier charges separately for Zap executions based on your Zapier plan.
