All requests to the Contacts API require proper authentication. Use OAuth 2.0 tokens with the scope ‘contacts.readonly’ (and additional scopes if you write data). Store credentials securely and rotate them per your security policy.
Base44 connects to GHL using a secure OAuth flow. You will authorize the app once, grant the required scopes, and Base44 will refresh tokens as needed to keep your integration active.

Trigger: when a contact is created or updated in GHL, the change is pushed to Base44 instantly.
Actions: create or update the corresponding contact in Base44; update related tasks and notes to keep data aligned.
Method path: GET /contacts/:contactId for fetches and POST /contacts/ to seed data.
Key fields: contactId, email, and phone are used to match records across systems.
Trigger: updates to tasks or notes for a contact trigger sync to Base44.
Actions: pull tasks (GET /contacts/:contactId/tasks) and notes (GET /contacts/:contactId/notes) into Base44 and reflect changes.
Method path: GET /contacts/:contactId/tasks; GET /contacts/:contactId/notes
Key fields: contactId, taskId, noteId.
Trigger: updates to notes or appointments propagate to a complete contact timeline in Base44.
Method path: GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments
Key fields: contactId, noteId, appointmentId.

Key elements and processes: authentication, endpoints, triggers, actions, and data mapping between GHL Contacts API and Base44.
A person stored in GHL with associated details like name, email, phone, notes, tasks, and appointments.
A to-do item linked to a contact used to track activities and progress.
A memo or message attached to a contact for context or history.
A scheduled event associated with a contact, used for meetings or calls.
Automatically create a new contact in Base44 when a new lead arrives in GHL via API and kick off a welcome task sequence.
Sync contact-related tasks to Base44 to keep support teams aligned and informed.
Aggregate notes and appointments into a unified contact timeline in Base44 for richer context.
Register your app in the GHL developer portal and obtain client credentials.
Run the OAuth flow in Base44 to grant the required scopes (including contacts.readonly).
Run test actions, review logs, and then enable live syncing.
With the Contacts API, you can read core contact data, notes, tasks, and appointments tied to each contact. The high-level capabilities cover retrieving, listing, and aggregating related records to fuel your workflows. This enables you to surface a complete picture of a contact’s history within Base44.\nIf you need write operations, you can upgrade scopes and use endpoints like POST, PUT, and DELETE to create or update contacts, tasks, and notes as part of a controlled automation flow.
No code is required to start. Base44 provides a visual connector to link GHL’s Contacts API endpoints to your Zapier workflows. You authenticate once, configure triggers and actions, and your data moves between systems automatically. Advanced use cases may still benefit from custom mappings, but for most scenarios you can set up a powerful integration without writing code.
Authentication is handled via OAuth 2.0 between GHL and Base44. You will authorize the Base44 app to access your Contacts API resources with the required scopes (such as contacts.readonly). After consent, tokens are refreshed automatically to keep the connection alive. Always adhere to best practices for token management and scope minimization.
If you hit errors, check authentication tokens, endpoint paths, and required scopes first. Rate limits are documented for the API and Base44 retries are automatic, but you can also implement exponential backoff in your workflow. Logs in Base44 will help you pinpoint the exact failing call and response.
Base44 provides troubleshooting tips and logs for each connector run. You can review run details, error messages, and response payloads to diagnose issues and adjust your mappings or scopes as needed.
Due to high volume, we will be upgrading our server soon!
