Access the Contacts API from CalendarHero using OAuth 2.0 and API keys. Use the scope: contacts.readonly (and additional write scopes as needed). Store credentials securely and rotate regularly.
To authorize CalendarHero to talk to the Contacts API, configure OAuth 2.0 or an API key in your GHL developer settings and grant the required scopes. Keep client secrets secure.
GET /contacts/:contactId — Retrieve a single contact\nGET /contacts/:contactId/tasks — List tasks for a contact\nGET /contacts/:contactId/tasks/:taskId — Retrieve a specific task\nGET /contacts/:contactId/notes — Retrieve notes for a contact\nGET /contacts/:contactId/notes/:id — Retrieve a note\nGET /contacts/:contactId/appointments — Retrieve appointments for a contact\nGET /contacts/ — List all contacts\nGET /contacts/business/:businessId — Retrieve contacts by business\ncontacts.write — permission to modify contacts\nPOST /contacts/ — Create a contact\nPUT /contacts/:contactId — Update a contact\nDELETE /contacts/:contactId — Delete a contact\nPOST /contacts/:contactId/tasks — Create a task for a contact\nPUT /contacts/:contactId/tasks/:taskId — Update a task\nPUT /contacts/:contactId/tasks/:taskId/completed — Mark a task as completed\nDELETE /contacts/:contactId/tasks/:taskId — Delete a task\nPOST /contacts/:contactId/tags — Add tags to a contact
Trigger: when a contact milestone is updated in the Contacts API, CalendarHero creates a corresponding calendar event.
Actions: create and update events, set reminders, attach notes.
Method path: use GET /contacts/:contactId to pull data, then POST to create events in CalendarHero using mapped milestone data.
Key fields: contactId, milestone, eventDate, title.
Trigger: new or updated tasks in the Contacts API should reflect in CalendarHero as calendar tasks.
Actions: create or update calendar tasks, set due dates and reminders.
Method path: POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId to sync state.
Key fields: taskId, contactId, dueDate, status.
Trigger: notes added or updated in the Contacts API trigger notes in CalendarHero and apply relevant tags.
Actions: sync notes, create calendar notes, propagate tags.
Method path: GET /contacts/:contactId/notes and POST /contacts/:contactId/tags to map notes and tags.
Key fields: noteId, tagId, contactId.
Automate repetitive workflows with click‑and‑configure triggers and actions—no code required.
Centralize contact data across Apps so updates propagate automatically.
Accelerate deployment with ready‑to‑use endpoints and templates.
This glossary defines API, OAuth, endpoints, triggers, actions, and data mapping used in this integration.
Application Programming Interface: a set of rules that allows apps to communicate and share data.
OAuth 2.0: a standard protocol for secure delegated access to user data without sharing passwords.
Webhook: a callback URL that receives real-time notifications when events occur in an app.
Endpoint: a specific URL in an API that performs an action or returns data.
Automatically generate calendar events when a contact reaches a defined milestone in the Contacts API.
Push calendar reminders when tasks in the Contacts API are updated.
Sync rich notes and tags to CalendarHero timelines for better context.
Create an API key or OAuth client in the Contacts API settings and note the required scopes.
Enable endpoints and test connectivity using sample requests like GET /contacts/:contactId.
In CalendarHero, create automations that listen for events and map fields accordingly.
Answer: Use OAuth 2.0 or API keys to authorize access. In most cases you’ll assign the scope contacts.readonly (and additional write permissions if you need to create or modify records). Test with sandbox credentials and sample requests to verify that authentication works and that you can successfully retrieve data from endpoints such as GET /contacts/:contactId.
Answer: For calendar syncing you’ll typically need read access to contacts and write access to calendars or tasks. Essential endpoints include GET /contacts/:contactId, GET /contacts/:contactId/appointments, GET /contacts/:contactId/tasks, and corresponding POST/PUT endpoints to create or update records. Map the fields between apps to ensure calendar events reflect contact data accurately. Always verify permissions in your connected app and test with representative data before going live.
Answer: Availability depends on your plan and access to API features. Some plans require a developer or integration add-on to obtain API credentials. Check your subscription and enable API access in your account settings. If in doubt, contact support to confirm eligibility and obtain the necessary keys or OAuth credentials.
Answer: Start by enabling a sandbox environment and use test accounts. Generate test credentials, then run sample requests like GET /contacts/:contactId and POST /contacts/ to validate authentication and data retrieval. Use logging to trace requests and responses, and adjust scopes as needed to ensure required permissions are granted.
Answer: Yes, if your credentials grant write access. You can create or update contacts, tasks, notes, and tags from CalendarHero, subject to the scopes granted. Ensure you follow the API’s rate limits and proper data mapping. Always test with non-production data first to prevent unintended changes.
Answer: Data mapping typically follows: contactId maps to a contact, tasks map to tasks with dueDate and status, notes map to notes with content, and tags map to tag fields. Establish field mappings in your automation rules so updates in one app reflect correctly in the other. Document the mapping to maintain consistency as your integration evolves.
Answer: Common errors include 401/403 authentication errors, 404 endpoint not found, and 429 rate limits. Ensure tokens or keys are valid, scopes are correct, and endpoints are properly formed. Implement retry logic and monitor quotas. Consult the API reference and your app logs to diagnose and resolve issues quickly.
Due to high volume, we will be upgrading our server soon!
