Automate Mautic Contact Updates with Calendly Events in n8n

Opening Problem Statement

Meet Sarah, a busy marketing manager juggling countless Calendly events daily. Each new invitee means manually updating contact records in her Mautic marketing platform — a tedious process eating up hours every week. She often faces data inaccuracies; contacts sometimes bear incorrect names due to manual entry errors. This inconsistency disrupts campaign targeting and wastes valuable team time. Does this sound familiar? If you rely on Calendly for scheduling and Mautic for contact management, keeping these two in sync manually is inefficient and error-prone.

What This Automation Does

This n8n workflow streamlines Sarah’s struggle by automating contact management between Calendly and Mautic. When a new Calendly event invitee is created, the workflow triggers and updates her Mautic contact list seamlessly.

• Automatically detects new invitees via the Calendly Trigger node.
• Pulls key contact details, such as email and first name, from the Calendly event payload.
• Creates a new contact in Mautic if the email does not exist.
• Updates the first name of existing Mautic contacts when a matching email is found.
• Saves hours of repetitive manual data entry each week.
• Ensures contact data accuracy across scheduling and marketing platforms.

Prerequisites ⚙️

• n8n account to build and run the workflow.
• Calendly account with API access to capture event invitee data.
• Mautic account with API credentials to create and update contacts.
• API credentials for both Calendly and Mautic configured in n8n.
• Optional: A self-hosted n8n instance for full control (consider hosting options like this).

Step-by-Step Guide to Building This Workflow

Step 1: Setup Calendly Trigger Node

Navigate to your n8n editor. Click + Add Node → search for Calendly Trigger. Select it.

Configure the node by setting the Events parameter to invitee.created. This tells n8n to trigger the workflow whenever a new invitee event happens in Calendly.

You will need to link your Calendly API credentials here. Click on Credentials, create new, and enter your Calendly API key. Save and test the credentials.

Once configured, activate the webhook URL provided by the node in your Calendly webhooks settings to ensure events trigger your workflow.

Common mistake: Forgetting to activate the webhook in Calendly will cause no triggers to occur.

Step 2: Add Mautic Node to Create or Update Contacts

Next, click + Add Node, search for Mautic, and select the Create/Update Contact operation.

Set the Email field source to the email received from the Calendly Trigger node with this expression: {{$node["On new event"].json["payload"]["email"]}}. This dynamically fetches the invitee’s email.

Set the First Name field to the invitee’s name from the Calendly payload using: {{$json["payload"]["name"]}}.

Attach your Mautic API credentials by creating or selecting them under the Credentials tab.

This node will check if a contact exists by email and update its first name or create a new contact accordingly.

Common mistake: Mismatching field names or incorrect credentials will result in failure to update or create contacts.

Step 3: Connect the Nodes

Connect the Calendly Trigger node output to the Create/Update Contact node input.

This logical connection ensures when a Calendly event fires, the Mautic contact action immediately follows.

Step 4: Optional Note Node for Workflow Documentation

Add a Sticky Note node to the canvas and document your workflow steps clearly for future reference.

This helps team members understand and maintain the automation easily.

Customizations ✏️

• Add More Contact Fields in Mautic: In the Create/Update Contact node, expand the Additional Fields section and map other Calendly data like phone or company.
• Trigger on Other Calendly Events: In the Calendly Trigger node, update the Events array to include events like invitee.canceled to handle removals.
• Send Notification Emails: Add a Email Send node after creating/updating contact to notify your sales team of new invitees.

Troubleshooting 🔧

• Problem: “No trigger on new Calendly invitee”
  Cause: Webhook not activated in Calendly.
  Solution: Log in to Calendly, under integrations, confirm webhook subscription is active for your n8n webhook URL.
• Problem: “Mautic contact not created or updated”
  Cause: Invalid or expired API credentials.
  Solution: Verify API credentials in n8n, reconnect or refresh them as needed.

Pre-Production Checklist ✅

• Verify Calendly webhook subscription is active and test with a sample invitee creation.
• Check Mautic API credentials and permissions to create or update contacts.
• Test the workflow manually by triggering a new invitee event in Calendly and observe contact creation/updating in Mautic.
• Document all API keys securely and have a backup plan if workflows fail.

Deployment Guide

Activate the workflow toggle in n8n to start listening for new Calendly invitee events.

Monitor the execution logs within n8n for failures or errors and adjust API credentials or webhook settings as needed.

Scheduling periodic reviews helps keep integrations healthy as APIs or platform updates occur.

FAQs

• Can I use other scheduling tools instead of Calendly?
  Currently, this workflow is designed specifically for Calendly’s webhook events, but you could replace the trigger node with other supported scheduling integrations with some modifications.
• Does this consume API credits?
  Mautic itself generally does not limit API usage, but check your account plan. Calendly webhook calls count as events but are lightweight.
• Is my data secure?
  Yes, using API credentials within n8n is safe as long as your n8n instance is secured. Avoid exposing webhook URLs publicly.

Conclusion

By following this guide, you’ve automated the tedious task of syncing Calendly invitees with Mautic contacts. Sarah will no longer waste hours updating records manually, maintaining accurate data for targeted marketing campaigns.

This automation saves significant manual effort, reduces errors, and keeps your marketing database fresh with the latest scheduling data.

Next steps could include expanding to sync other contact details, integrating follow-up emails, or adding other CRM systems for comprehensive contact management.

Keep exploring n8n’s potential to connect your tools and automate your workflows seamlessly. You’ve got this!
