OpenClaw + Calendly: Automated Scheduling Workflows

5 min read ·

Why Connect OpenClaw to Calendly?

Calendly handles scheduling — but what happens before and after the booking is where most teams lose efficiency. Someone books a sales call, and then the rep spends 15 minutes researching the prospect. A client books a consultation, and the follow-up email goes out 3 days late. Connecting OpenClaw to Calendly automates these surrounding workflows.

Tested in production with a sales team processing 50+ Calendly bookings per week, the integration delivered two major improvements: automated pre-meeting research briefs (pulling prospect data from LinkedIn and the CRM before each call) and instant post-meeting follow-up sequences (triggered the moment a meeting ends).

For meeting recording and transcript processing, pair this with the Zoom integration. For CRM updates triggered by bookings, combine with the HubSpot integration. New to OpenClaw? Start with the beginner setup guide.


Prerequisites


Step-by-Step Setup

Step 1: Generate a Calendly Personal Access Token

In Calendly, go to Settings > Integrations > API & Webhooks and generate a Personal Access Token:

# Store your Calendly token
export CALENDLY_TOKEN="your_personal_access_token"

# Verify the token and get your user URI
curl -s -H "Authorization: Bearer $CALENDLY_TOKEN" \
  "https://api.calendly.com/users/me" | jq '{name: .resource.name, uri: .resource.uri}'

Step 2: Find Your Organization and Event Types

# List your event types
curl -s -H "Authorization: Bearer $CALENDLY_TOKEN" \
  "https://api.calendly.com/event_types?user=YOUR_USER_URI" | jq '.collection[] | {name: .name, slug: .slug, uri: .uri}'

Step 3: Configure OpenClaw

# ~/.openclaw/config.yaml
integrations:
  calendly:
    access_token: ${CALENDLY_TOKEN}
    user_uri: "https://api.calendly.com/users/YOUR_USER_ID"
    webhook_url: "https://your-openclaw-instance.com/webhooks/calendly"
    pre_meeting_prep: true
    prep_lead_time: 30  # minutes before meeting

skills:
  - name: calendly-manager
    trigger: "calendly"
    actions:
      - list_events
      - get_event_details
      - list_invitees
      - create_webhook
      - pre_meeting_brief
      - post_meeting_followup

Step 4: Set Up Webhooks (Professional Plan)

# Create a webhook subscription for new bookings
curl -s -X POST "https://api.calendly.com/webhook_subscriptions" \
  -H "Authorization: Bearer $CALENDLY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://your-openclaw-instance.com/webhooks/calendly",
    "events": ["invitee.created", "invitee.canceled"],
    "organization": "YOUR_ORG_URI",
    "scope": "organization"
  }' | jq '.resource.uri'

Step 5: Install and Test

# Install the Calendly skill
openclaw skill install calendly-manager

# Test listing upcoming events
openclaw run "List all Calendly events scheduled for this week with invitee names and meeting types"

# Test pre-meeting brief
openclaw run "Generate a pre-meeting brief for my next Calendly booking: look up the invitee's company, role, recent news, and any prior interactions in our CRM"

Example Use Cases

1. Automated Pre-Meeting Research

schedule:
  pre_meeting_prep:
    cron: "*/30 * * * *"
    action: "Check Calendly for meetings starting in the next 30 minutes. For each meeting, generate a prep brief: invitee name, company, role, LinkedIn profile summary, recent company news, any existing CRM records, and suggested talking points. Send the brief via Slack or email."

2. Post-Booking CRM Updates

When someone books a Calendly meeting, OpenClaw automatically creates or updates their record in HubSpot with the meeting type, date, and any form responses from Calendly's booking questions:

# Triggered by Calendly webhook
on_event: "invitee.created"
action: "Look up the invitee email in HubSpot. If contact exists, log the meeting and update the deal stage. If new, create a contact with the booking details and assign to the appropriate sales rep based on the event type."

3. No-Show Follow-up

If someone books but does not show up, OpenClaw can detect the no-show (via Zoom integration) and automatically send a rescheduling email with a new Calendly link.


Troubleshooting Tips

Webhook Not Firing

Webhooks require Calendly Professional or Teams plan. If you are on the free plan, webhooks will not be created. Also verify your webhook endpoint is publicly accessible via HTTPS and returns a 200 status code within 10 seconds.

Events Not Listing

Make sure you are using the correct user_uri parameter. The Calendly API returns events scoped to the authenticated user by default. For organization-wide access, use the organization URI with appropriate permissions.

Token Permissions

Personal Access Tokens in Calendly have full access to the account they belong to. If you need to limit access (e.g., for a team member), use OAuth 2.0 with specific scopes instead of a PAT.


Limitations and Known Issues

  • Cannot create event types: The Calendly API does not support creating or modifying event types. These must be managed through the Calendly dashboard. OpenClaw can only read event types and scheduled events.
  • Limited free plan support: Webhooks and some advanced API features require Calendly Professional ($10/month) or Teams ($16/month per seat).
  • No direct scheduling: OpenClaw cannot book meetings on behalf of invitees through the API. It can share scheduling links and manage existing bookings, but the actual booking must happen through Calendly's scheduling page.
  • Webhook reliability: Calendly webhooks occasionally experience delays during high-traffic periods. For critical workflows, implement a polling fallback that checks for new events every 5 minutes.

Frequently Asked Questions

Does the Calendly integration work with the free plan?

Partially. Calendly's free plan allows API access for reading event types and scheduled events. However, webhooks (which enable real-time automation) require Calendly Professional or higher. For full automation, we recommend Calendly Professional at minimum.

Can OpenClaw create Calendly scheduling links automatically?

OpenClaw can list existing event types and their scheduling links but cannot create new event types through the API. Event types must be created in the Calendly dashboard. OpenClaw can dynamically select and share the appropriate scheduling link based on context.

How does OpenClaw handle Calendly cancellations and reschedules?

OpenClaw receives webhook notifications for cancellations and reschedules. It can automatically update your CRM, notify relevant team members, remove related tasks, and update your daily schedule. You can also configure it to send a follow-up message to the person who cancelled with a new scheduling link.

Can I use OpenClaw to block calendar time based on Calendly bookings?

Calendly already syncs with Google Calendar, Outlook, and iCloud to block time. OpenClaw adds intelligence on top — for example, blocking 15 minutes before each meeting for preparation time, or blocking focus time around high-priority meetings to prevent back-to-back scheduling.
