Make.com Integration

Connect LinkTime to 1000+ apps using Make.com (formerly Integromat) and webhooks.

Overview

LinkTime webhooks allow you to receive real-time notifications when bookings are created, cancelled, rescheduled, or paid. Combined with Make.com, you can automate workflows like:

  • Add new invitees to your CRM (HubSpot, Salesforce, Pipedrive)
  • Send Slack or Teams notifications for new bookings
  • Create tasks in Asana, Notion, or Monday.com
  • Add contacts to email lists (Mailchimp, ConvertKit)
  • Log meeting activity in spreadsheets

Step 1: Create a Webhook in LinkTime

  1. 1

    Go to Webhooks Settings

    Navigate to Settings → Webhooks in your LinkTime dashboard.

  2. 2

    Click "Create Webhook"

    You'll need to provide a URL (we'll get this from Make.com in Step 2) and select which events to receive.

  3. 3

    Copy the Webhook Secret

    After creation, you'll see the webhook secret once. Save it somewhere secure — you'll need it to verify webhook signatures (optional but recommended).

Step 2: Set Up Make.com Scenario

  1. 1

    Create a New Scenario

    Log in to Make.com and create a new scenario.

  2. 2

    Add a "Custom Webhook" Trigger

    Search for "Webhooks" in the app list and select "Custom webhook". Click "Add" to create a new webhook.

  3. 3

    Copy the Webhook URL

    Make.com will generate a unique URL like https://hook.make.com/abc123...

  4. 4

    Paste URL in LinkTime

    Go back to LinkTime and paste this URL when creating your webhook. Save the webhook.

  5. 5

    Send a Test Webhook

    In LinkTime, click the "Test" button on your webhook. This sends a sample payload to Make.com, which will automatically detect the data structure.

Available Webhook Events

EventDescription
booking.createdTriggered when a new booking is confirmed
booking.cancelledTriggered when a booking is cancelled
booking.rescheduledTriggered when a booking is moved to a new time
payment.receivedTriggered when payment is completed for a paid booking
contact.createdTriggered when a new contact is added (from booking or manually)

Webhook Payload Structure

All webhook payloads follow this structure. You can use these fields in Make.com to map data to other apps.

  "event": "booking.created",
  "timestamp": "2026-02-06T15:30:00.000Z",
  "data": {
    "id": "clx123abc...",
    "eventType": {
      "id": "clx456def...",
      "name": "30 Minute Meeting",
      "slug": "30-min",
      "duration": 30
    },
    "startTime": "2026-02-07T14:00:00.000Z",
    "endTime": "2026-02-07T14:30:00.000Z",

    "isRecurring": false,
    "recurringGroupId": null
  }
}

Additional Fields by Event

booking.cancelled

Includes cancelReason if provided

booking.rescheduled

Includes previousStartTime and previousEndTime

payment.received

Different structure: bookingId, amount, currency, paymentMethod, transactionId

contact.created

Contact fields: id, name, email, phone, company, notes, source (booking/manual/payment)

Common Automation Scenarios

Slack Notification for New Bookings

LinkTime WebhookSlack: Send Message

Use data.invitee.name and data.startTime in your Slack message.

Add Contact to HubSpot CRM

LinkTime WebhookHubSpot: Create Contact

Map data.invitee.email to Email and data.invitee.name to Name.

Log to Google Sheets

LinkTime WebhookGoogle Sheets: Add Row

Create columns for Name, Email, Event Type, Date, and map the corresponding fields.

Create Asana Task on Cancellation

LinkTime WebhookFilter: booking.cancelledAsana: Create Task

Use a Filter module to only process event = booking.cancelled, then create a follow-up task.

Security: Verifying Webhook Signatures

Every webhook includes an HMAC-SHA256 signature in the X-LinkTime-Signature header. While optional, verifying signatures ensures the webhook came from LinkTime.

Headers included with every webhook:

  • X-LinkTime-Signature — HMAC-SHA256 signature (sha256=...)
  • X-LinkTime-Event — Event type (booking.created, etc.)
  • X-LinkTime-Timestamp — ISO 8601 timestamp

To verify in Make.com, you can use a "Custom function" or "Code" module with this logic:

// JavaScript example for verification
const crypto = require('crypto');

function verifySignature(payload, signature, secret) {
  const expected = 'sha256=' + crypto
    .createHmac('sha256', secret)
    .update(payload, 'utf8')
    .digest('hex');

  return signature === expected;
}

// Usage:
// payload = raw JSON body as string
// signature = X-LinkTime-Signature header value
// secret = your webhook secret (whsec_...)

For most Make.com scenarios, signature verification is optional since Make.com URLs are unique and not easily guessable.

Troubleshooting

Webhook not receiving data

Make sure your Make.com scenario is "Active" (turned on). Check the webhook delivery history in LinkTime → Settings → Webhooks → Click on your webhook to see recent deliveries.

Make.com shows "Waiting for data"

Click the "Test" button on your webhook in LinkTime. This sends a sample payload that Make.com will use to detect the data structure.

Deliveries showing errors

Check the status code in the delivery history. A 400 error usually means Make.com couldn't parse the data. Try sending another test webhook. A timeout error means Make.com took too long to respond (keep scenarios simple for fastest processing).
