Use OAuth 2.0 or API key based on your setup to securely authorize the Calendars API. Ensure the calendars.write scope is granted for full create and update capabilities.
Provide your ActiveCampaign API credentials to authorize the connection. Use a secure method to store keys and grant the necessary scopes for calendar data access.
Endpoints included: POST /calendars/; PUT /calendars/:calendarId; DELETE /calendars/:calendarId; calendars.readonly; GET /calendars/; GET /calendars/:calendarId; GET /calendars/:calendarId/free-slots; calendars/groups.readonly; GET /calendars/groups; calendars/groups.write; POST /calendars/groups; POST /calendars/groups/validate-slug; DELETE /calendars/groups/:groupId; PUT /calendars/groups/:groupId; PUT /calendars/groups/:groupId/status; calendars/resources.readonly; GET /calendars/resources/:resourceType
Trigger: When a new calendar is created in Calendars API, push core details to ActiveCampaign to create or update a related contact field or asset.
Actions: Create or update a corresponding Calendar entry in ActiveCampaign; map calendarId, name, and timezone; optionally create a task or event in campaigns.
POST /calendars/
calendarId, name, timezone
Trigger: Updated calendar fields in ActiveCampaign should update the corresponding calendar in Calendars API.
Actions: PUT /calendars/:calendarId to sync changes; include calendarId, name, timezone.
PUT /calendars/:calendarId
calendarId, name, timezone
Trigger: When a user requests availability, fetch free slots from the calendar.
Actions: Retrieve GET /calendars/:calendarId/free-slots and pass results to ActiveCampaign for scheduling.
GET /calendars/:calendarId/free-slots
calendarId, dateRange

Sync calendar changes to contact fields and segments for personalized outreach.
Use free-slots data to present booking options inside ActiveCampaign automations.
Create a developer key and obtain OAuth tokens or an API key to authorize the connection.
Select Calendars API as the GHL integration and ActiveCampaign as the app; map fields between systems.
Run tests for triggers and actions, then deploy to production after success.
The connection uses OAuth 2.0 or API keys to securely authenticate. Choose the method supported by your GHL setup and grant the calendars.write scope for creating and updating calendars. If you are using OAuth, ensure refresh tokens are stored securely and rotated as needed. In most cases, you can test authentication within the App Connector by triggering a test call to a calendar endpoint and verifying the response.
Commonly used endpoints include POST /calendars/ for creation, GET /calendars/ to list calendars, GET /calendars/:calendarId to fetch details, and GET /calendars/:calendarId/free-slots to check availability. The App Connector also supports grouping via calendars/groups.* endpoints for organizing calendars. Use endpoint examples in the docs to validate your integration and to build practical automations.
Yes. You can configure read-only access using calendars.readonly to pull calendar data without permitting modifications. However, to sync data back into calendars, write access is typically required. Always follow the principle of least privilege and test permissions in a staging environment.
Open the App Connector test panel and run sample triggers and actions. Check the API responses for status codes, error messages, and payload structure. Confirm that data fields map correctly between systems and that updates propagate as expected. Review any rate-limit responses and adjust polling intervals accordingly.
Rate limits depend on your GHL plan and endpoints used. Typically you will see limits on calls per minute or per hour. If you hit limits, implement exponential backoff in your workflow and batch requests where possible. Monitor usage via the App Connector statistics to stay within quotas.
Yes, you can map calendars to different ActiveCampaign lists or tags. Use field mappings and segment automation in ActiveCampaign to assign records to the correct lists. If multiple lists are required, consider using bulk operations or separate automations. Carefully plan slugs and groupings to avoid duplicates.
Yes. The App Connector supports no-code workflow building with triggers, actions, and mappings. You can create automations based on calendar events and free-slot responses without writing code.
