What you can automate

What can you automate with the Synthflow AI Phone Calling Make integration?

The integration lets Make, a no-code automation tool, ask Synthflow to place an AI phone call as a step in a scenario, meaning the chain of steps you build in Make. Something happens in another app, and a call goes out with the data that app passed along, without anyone opening Synthflow.

A lead is called while still warm. A form or a CRM hands a new contact to Make, and Make a AI Phone Call starts the conversation. Sales reps pick up the qualified conversations instead of chasing every sign-up.

A reminder call goes out after a booking. When a scheduling tool records an appointment, the same module can phone the customer, so a clinic or an agency stops calling each client by hand.

Anything else the API offers stays reachable. Make an API Call uses the same connection to call any endpoint of the Synthflow API, which covers the requests the dedicated module leaves out.

Know the limits before you start. Synthflow has no trigger module in Make, so a scenario never starts from Synthflow itself: it starts from another app or from a schedule. Make's documentation page for Synthflow also carries a notice that it was generated by AI and may contain mistakes, so check important details with Synthflow. If you weigh the alternatives, the n8n vs Make comparison lays out the criteria, and the Make pricing guide explains how operations are counted.

Connect

How do you connect Synthflow AI Phone Calling to Make?

  1. 01

    Create an API key in Synthflow

    In your Synthflow dashboard, open Integrations in the sidebar, then REST API, and click Create New API Key. Copy the key shown on screen. You need an active Synthflow account for this step.

  2. 02

    Add a Synthflow module in Make

    In your scenario, add a Synthflow AI Phone Calling module and click Create a connection. A connection is your Synthflow account linked to Make once, then reused by both modules. You can type a label in Connection name if you plan to link several accounts.

  3. 03

    Paste the key and save

    Paste the API key you copied into the credentials field and confirm. Make now holds the connection, and the fields of the module you picked open so you can fill them.

First scenario

Your first scenario with Synthflow AI Phone Calling

GoalWhen another app sends a new contact, Make asks Synthflow to call that person with your AI agent.

  1. 01

    Create the scenario

    From the Scenarios page, create a new scenario and click the + to add the first module. Pick the app that holds your contacts, such as a form or a CRM, and its trigger.

  2. 02

    Add the call module

    Click the + on the right of that first module, search for Synthflow AI Phone Calling and choose Make a AI Phone Call. Select the connection you created, or click Create a connection now.

  3. 03

    Map the contact data

    Fill the module fields with data from the first module: click a field and pick the value the trigger delivered. Each contact travels as a bundle, one item passed from a module to the next.

  4. 04

    Test with Run once

    Click Run once and create a test contact in the first app. Make runs the scenario one time; open the bubble on each module to read the bundles it received and check that the call left.

  5. 05

    Schedule and switch on

    Set the schedule on the first module (every 15 minutes by default, if it is a scheduled trigger) and switch the scenario on. From then on, each new contact leads to a call.

Modules

What the Synthflow AI Phone Calling modules do

Synthflow AI Phone Calling gives you 2 modules. For each one: what it does for you, when to reach for it, and what to watch out for.

Synthflow AI Phone Calling1

Make a AI Phone Call

Action

In Make“Makes a Phone Call”

You get a phone call placed through Synthflow as a step of your scenario, so a person hears from your AI agent with the details the earlier modules passed on.

When to use it
a lead fills a form, a booking is confirmed or a ticket needs a follow-up, and a spoken contact beats an email.
Watch out
every bundle that reaches this module becomes a call, so filter the flow before it if some contacts should not be phoned.
Synthflow AI Phone Calling2

Make an API Call

Action

In Make“Performs an arbitrary authorized API call.”

Sends a request of your choice to any endpoint of the Synthflow API, reusing the connection you already created. It is the way to reach what the call module does not expose, without a second setup.

When to use it
the action you need is missing from Make a AI Phone Call and the Synthflow API documentation describes an endpoint for it.
Watch out
you write the request yourself, so read Synthflow's API reference first and test it with Run once before the scenario goes live.

FAQ

Questions about Synthflow AI Phone Calling and Make

01Is the Synthflow AI Phone Calling Make integration free?
Yes on the Make side: Synthflow AI Phone Calling is a standard app, available from the Free plan. That plan allows 2 active scenarios, a minimum of 15 minutes between two scheduled runs, 5 minutes of execution per run, files up to 5 MB and 512 MB of data transfer. Paid plans (Core, Pro, Teams and Enterprise) lower the interval to 1 minute and count usage in operations, one execution of one module on one bundle. You still need an active Synthflow subscription, which Synthflow bills separately.
02What do you need to connect Synthflow AI Phone Calling to Make?
An active Synthflow account and an API key. In the Synthflow dashboard, go to Integrations in the sidebar, then REST API, click Create New API Key and copy the key displayed. In Make, add a Synthflow AI Phone Calling module, click Create a connection, optionally name it, and paste the key. The same connection then serves both modules, Make a AI Phone Call and Make an API Call, so the setup happens once per account.
03Can Synthflow AI Phone Calling start a Make scenario in real time?
No. Synthflow has no trigger module in Make, neither scheduled nor instant, so it cannot start a scenario by itself. The scenario begins with another app instead: its trigger hands over a contact, then Make a AI Phone Call places the call. You can also start from Make's scheduling, the clock on the first module, which runs every 15 minutes by default. On the Free plan the interval cannot go below 15 minutes, and paid plans allow 1 minute.
04What if a Synthflow AI Phone Calling module is missing in Make?
Use Make an API Call. It reaches any endpoint of the Synthflow API with the connection you already set up, so the request you need can still be sent from the scenario even though only one dedicated action exists. You write the request yourself from the Synthflow API reference. Keep in mind that Make's documentation page for Synthflow is flagged as AI-generated and possibly inaccurate, so confirm the details with Synthflow when a result looks wrong.
05Should you use Make or n8n for Synthflow AI Phone Calling?
It depends on the tool your team already runs. In Make, Synthflow offers 2 modules: a dedicated call action and Make an API Call for the rest of the API, both on a single API key connection, available from the Free plan. Before choosing n8n, check whether a Synthflow node exists there and what it covers. Compare the two on the actions your workflow needs and on how each counts executions, not on reputation.
