Retell AI Make integrationAutomate Retell AI with Make.
Can Make place calls with your Retell AI voice agents? Yes. The Retell AI Make integration gives you 15 modules, one scheduled trigger included. This guide is for ops teams who run voice agents, and it walks you from the connection to a first working scenario.

What can the Retell AI Make integration do for you?
It links your Retell AI account to Make, so your voice agents, calls, phone numbers, voices and Retell LLMs become building blocks of a scenario, the automation you assemble in Make. Each block is a module: one trigger, nine actions and five searches here, all without writing code.
Call a lead the moment it appears. A form, a CRM or a spreadsheet feeds the scenario, and Create a Phone Call dials the person with your voice agent. Sales teams use this to reach a prospect while the interest is still warm.
Keep a log of every conversation. Watch Call spots each new call in your account and hands it to the next module, for example a row in a sheet or an Airtable Make integration base. Pair it with Get a Call when you need the full record of one specific call.
Audit your setup without clicking through the dashboard. The list modules return your agents, phone numbers, voices and Retell LLMs in one pass, and Get the Concurrency tells you how many calls run right now against your limit.
What the app does not cover: there is no instant trigger, so Make only sees new calls when it checks on schedule. Anything outside the 15 modules goes through Make an API Call, which reuses the same connection. If you are still weighing the tools, the n8n vs Make comparison lays out the criteria, and the Make training covers scenario building from scratch.
How do you connect Retell AI to Make?
- 01
Create an API key in Retell AI
Log in to Retell AI and open API keys in the left sidebar. Click Add, give the key a name you will recognize later, then copy its value somewhere safe. You need a Retell AI account for this, a Make account alone is not enough.
- 02
Open the connection window in Make
In your scenario, add any Retell AI module and click Create a connection. A connection is your Retell AI account linked to Make once, then reused by every Retell AI module. The Connection name field is optional, but a clear name helps when you manage several accounts.
- 03
Paste the key and save
Paste the value into the API Key field and click Save. If Make asks you to authenticate or confirm access, accept it. The module then shows your connection, and you can move on to its fields.
Your first scenario: call every new lead with Retell AI
GoalWhen a new lead lands in the app you already use, Make asks Retell AI to call that person with your voice agent.
- 01
Create the scenario
Open the Scenarios page, create a new scenario and click the big +. This first module is the starting point: pick the app where your leads arrive, such as your CRM or your form tool.
- 02
Add the Retell AI call
Click the + on the right of that first module, search for Retell AI and choose Create a Phone Call. Select your connection, or click Create a connection if this is your first Retell AI module.
- 03
Map the lead into the call
Fill the fields of the call module. Where it asks for data about the person, map it from the first module instead of typing it, so each lead gets its own call.
- 04
Test with Run once
Click Run once and add a test lead with your own number. Open the bubbles above each module to read the bundles, the items each module received and passed on.
- 05
Schedule and switch on
Set the schedule on the first module (every 15 minutes by default), then switch the scenario on. Each module run counts as one operation, the unit Make counts on your plan.
What starts a Retell AI scenario
1 module starts a scenario when something happens in Retell AI. A scheduled trigger is checked by Make on the scenario's schedule; an instant one is called by Retell AI as soon as it happens.
Watch Call
Scheduled triggerIn Make“Trigger when a new call is created.”
Watch Call picks up each new call created in your Retell AI account and sends it into your scenario as a bundle, one bundle per call. It is the only trigger this app offers, so any flow that reacts to calls starts here.
Everything the Retell AI app can do in Make
Retell AI gives you 14 modules in 7 groups. For each one: what it does for you, when to reach for it, and what to watch out for.
Agent Management
2 modulesList all the Agents
SearchIn Make“List all agents.”
This search gives you the full roster of voice agents in your account, each one as its own bundle. It is the quickest way to see which agents exist before you wire one into a call.
Get an Agent
ActionIn Make“Retrieve details of a specific agent”
Get an Agent returns the details of one voice agent you name, so a scenario knows exactly which agent it is dealing with. Choose it over the list search when you already know the agent.
Call Management
3 modulesGet a Call
ActionIn Make“Retrieves all call details.”
With Get a Call you pull the complete record of a single call your agents handled. It is the module to reach for when the rest of the scenario needs everything Retell AI knows about that one conversation.
Create a Phone Call
ActionIn Make“Create a new outbound phone call”
Create a Phone Call starts a new outbound call from Retell AI, so your voice agent rings someone because something happened elsewhere. This is the module that turns Make into a dialer for your agents.
List all the Calls
SearchIn Make“Retrieves a detailed list of all calls within a specified time range.”
List all the Calls brings back the calls from a time range you set, one bundle per call. It shows what your agents handled over that period without opening the Retell AI dashboard.
Phone Number Management
3 modulesList all the Phone Numbers
SearchIn Make“Lists all phone numbers.”
Here you get every phone number attached to your Retell AI account, each as a separate bundle. Handy when numbers multiply across teams and nobody remembers which one belongs to which campaign.
Get a Phone Number
ActionIn Make“Retrieves a specific phone number.”
Get a Phone Number fetches the details of one specific number in your account. Pick it rather than the list search when the scenario already knows which number matters.
Create a Phone Number
ActionIn Make“Buys a new phone number and binds agents.”
Create a Phone Number buys a new number in Retell AI and binds agents to it in the same step. It saves you a trip to the dashboard when a new team, region or campaign needs its own line.
Voice Management
2 modulesGet the Voice
ActionIn Make“Retrieve details of a specific voice”
Get the Voice returns the details of one voice you can give your agents. It is useful when a scenario documents or checks which voice sits behind a given agent.
List all the Voices
SearchIn Make“Lists all voices available to a user.”
List all the Voices shows every voice available to your account, one bundle each. Think of it as the menu you pick from when you set up or review an agent.
Concurrency Management
1 moduleGet the Concurrency
ActionIn Make“Retrieves the current concurrency and concurrency limit of a user.”
Get the Concurrency tells you how many calls are running at this moment and what your concurrency limit is. It protects outbound campaigns from firing more calls than your account can carry.
LLM Retell Management
2 modulesGet a Retell LLM
ActionIn Make“Retrieves details of a specific Retell LLM.”
Get a Retell LLM returns the details of one Retell LLM, the language model setup that drives what an agent says. Useful when you want a scenario to keep a written trace of how an agent is configured.
List all the Retell LLMs
SearchIn Make“Lists all retell LLM.”
List all the Retell LLMs returns every Retell LLM in your account, one bundle each. A good starting point when you lose track of which model setups exist and which ones are still in use.
Other
1 moduleMake an API Call
ActionIn Make“Performs an arbitrary authorized API call.”
Make an API Call lets you reach any endpoint of the Retell AI API from your scenario, with the connection you already set up. It covers whatever the other listed modules leave out, without a second connection.
