Overview

Create powerful automations between Callin.io and your favorite tools with n8n. Callin.io gives you its own n8n workspace at n8n.callin.io, with a ready-made Callin.io node that makes your AI agents start calls.

Video: Integrations → Go to n8n → sign in → add the Callin.io node → Start call → set up the credential with your API key from Profile → API Keys.

​
Steps

​
Step 1: What is n8n and Why Use It with Callin.io?

n8n (pronounced “en-eight-en”) is a workflow automation tool that connects different apps so they work together seamlessly. With Callin.io, this integration lets you:
  • Trigger outbound calls from external events: for example, when a new lead arrives in your CRM, when someone fills in a form on your website, or on a schedule. The Callin.io node has one action, Start call, which makes one of your AI agents call a contact.
  • Receive call data in n8n: send the details of each finished call to an n8n workflow with the agent’s Data Sync (Post-Call Webhook) (in the agent’s Call Action tab), and from there to Slack, Google Sheets, your CRM, etc.
In short: n8n turns events in your other tools into calls, and calls into actions in your other tools.
The Callin.io node has no triggers of its own. To start a workflow, use an n8n trigger (for example, On a Webhook call, On a Schedule or a trigger from your CRM) and then add the Callin.io node.

​
Step 2: Access the Callin.io Integrations Panel

1
Log in to your Callin.io account.
2
From the left menu, click Integrations → Actions (open it here).
3
Use the Automation filter (or scroll through All).
4
Find the N8N card and click Go to n8n.

​
Step 3: Sign In to Your n8n Account

1
A new tab opens on n8n.callin.io.
2
Enter your n8n Email and Password and click Sign in.
3
If you don’t have access yet, contact your Callin.io administrator.
Once inside, you’ll see the n8n Overview with your workflows, and the Create workflow button.

​
Step 4: Get Your Callin.io API Key

The Callin.io node needs an API key to act on your account.
1
In Callin.io, open your Profile (app.callin.io/profile) and go to the API Keys tab.
2
If you don’t have a key yet (“No API key found”), click Regenerate Key to create one.
3
Use the copy icon to copy the key.

Keep this API key secure. If you click Regenerate Key when you already have one, the old key stops working, and any workflow that uses it must be updated with the new key.

​
Step 5: Build Your First Automation

1
In n8n, click Create workflow.
2
Add a trigger that starts the flow (for example, On a Webhook call to receive a new lead from your website or CRM).
3
Click + to add the next step, search for Callin.io and choose the Start call action.

In Credential, click Set up credential, paste your Callin.io Api Key and click Save. Then fill in the Start call fields:
  • Phone: the number the agent will call.
  • Name: the contact’s name.
  • Email: the contact’s email.
  • Agent Name or ID: the agent that will make the call (the list appears once the credential is set up).
  • Webhook Url (optional): a URL to send the call data to.
  • Additional Fields: click Add Field to send extra data as Field Name / Field Value pairs.
Start call node parameters in n8n: Credential, Resource Callin, Operation Start Call, Phone, Name, Email, Agent Name or ID, Webhook Url (optional) and Additional Fields

Screenshot: The Start call parameters, filled in with an example contact.

Instead of typing fixed values, map the data from the previous step with n8n expressions (for example, {{ $json.phone }} for the phone number your form or CRM sends).

​
Step 6: Activate and Test

1
Click Execute step (or Execute workflow) to run a test call with a real number you control.
2
When everything works, click Publish so the workflow runs automatically.

​
Tips & Notes

  • Map your data: Use n8n expressions to pass values from the trigger (name, phone, email) into the Start call fields.
  • Conditional Logic: Add IF or Switch nodes for more complex automations (for example, only call leads from a certain country).
  • Get call results back: Paste the URL of an n8n On a Webhook call trigger into the agent’s Data Sync (Post-Call Webhook) to receive the details of every finished call in n8n.
  • Chained Flows: Combine Callin.io with CRMs and messaging tools in one continuous process.

​
Troubleshooting

Symptom: The Agent Name or ID list is empty
Likely Cause: The credential isn’t set up or the API key is wrong. Set up the credential again with a valid key from Profile → API Keys. Symptom: It stopped working after a key change
Likely Cause: The API key was regenerated. Update the credential in n8n with the new key. Symptom: Flow not running
Likely Cause: Make sure the workflow is published and that its trigger is receiving data. Symptom: The call isn’t made
Likely Cause: Check that Phone contains a valid number in international format (for example, +393339876543) and that the agent has a phone number assigned.

Final Note

Connecting Callin.io with n8n unlocks a world of smart automation.
Start small—like calling every new lead from your website form—and soon you’ll see how n8n turns Callin.io into an intelligent automation hub.
