To access Contacts data from Universe, generate an API key or OAuth token with the contacts.readonly scope. Keep credentials secure.
Grant Universe permission to access your Contacts API. Use the provided client ID and secret to complete OAuth flow or API key setup.

GET /contacts/:contactId
Required: contactId; Optional: email or name for lookup
Trigger: When you need an up to date list of tasks for a contact.
Actions: GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, DELETE /contacts/:contactId/tasks/:taskId
GET /contacts/:contactId/tasks
Required: contactId; taskId for updates; status
Trigger: Retrieve notes and appointments to surface a complete activity timeline.
Actions: GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id, GET /contacts/:contactId/appointments
GET /contacts/:contactId/notes
Required: contactId; noteId or appointmentId for specific entries
Faster data flows without custom code thanks to visual wiring in app connectors.
Automate routine tasks like syncing contacts and updating statuses across platforms.
Reduce errors and save time with centralized data governance between GHL and Universe.
This glossary covers core data elements: Contact, Task, Note, Appointment, Tag, and the API methods used to manipulate them.
A person stored in GHL with identity details and interaction history.
A to-do item linked to a contact, used for tracking activity and follow-ups.
A freeform text entry attached to a contact to capture context, comments, or updates.
Scheduled meeting or call with a contact, logged in history.
Set up a nightly sync to pull new or updated contacts into GHL with minimal latency.
Create or update GHL tasks when Universe triggers occur, ensuring follow-ups.
Attach Universe activity notes to GHL contact timelines for richer context.
Register or obtain API credentials and grant the app access to the Contacts API with the required scope.
Choose endpoints to enable and map fields to Universe data.
Run tests, validate data flow, and publish the integration.
The Contacts API lets you retrieve, update, and manage contact records inside GHL. When connected to Universe, you can pull contact data into Universe workflows to trigger automations and populate dashboards. It supports endpoints for reading contacts, their tasks, notes, appointments, and tags. In practice, you can assemble a seamless flow that starts with a contact in Universe and surfaces the updated details in GHL.
You can authenticate using OAuth 2.0 with scopes like contacts.readonly, plus standard security measures such as API keys or token-based access, depending on your setup. For many users, OAuth flow provides secure, per-user access to data. Always follow your security policy when handling credentials.
Read operations include GET endpoints for contact, tasks, notes, and appointments. Write operations cover POST, PUT, and DELETE endpoints for creating and updating records, including tag assignments. Use appropriate methods to keep Universe and GHL data in sync with minimal latency.
Use a sandbox or staging environment to test API calls. Validate response data structure and ensure the mapping between Universe and GHL fields is correct before going live. Create test contacts, tasks, notes, and appointments to verify end-to-end flow.
Most plans have rate limits; consider batching requests, using webhooks, and caching results to minimize calls and handle spikes gracefully. Implement retry logic and exponential backoff to maintain reliability.
Data is transmitted over HTTPS, access is controlled via OAuth or API keys, and endpoints use scoped permissions to prevent unauthorized access. Regularly rotate credentials and monitor access logs for unusual activity.
API documentation is available in the GHL developers portal and the Universe app connector docs, including endpoint references and example payloads. Refer to the latest guides for endpoint changes and versioning.
Due to high volume, we will be upgrading our server soon!
