The Contacts API scope allows read-only access to contact data. Use your GHL credentials to authorize requests and ensure secure access.
To connect Loyalzoo to the GHL Contacts API, grant permission for Loyalzoo to read and retrieve contacts notes tasks and related records as needed for your workflows.
Core endpoints include: GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/tasks/:taskId; GET /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id; GET /contacts/:contactId/appointments; GET /contacts/; GET /contacts/business/:businessId; POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/tags; plus the permission reference contacts.write.
Trigger: When Loyalzoo updates a contact, fetch the latest data into GHL to keep records aligned.
Actions: Create or update a contact in GHL; create related tasks; attach notes as needed.
Endpoint: GET /contacts/:contactId
Key fields: contactId, name, email, phone, status
Trigger: New or updated Loyalzoo notes should propagate to GHL notes.
Actions: Create / update notes in GHL; link to the corresponding contact; maintain timestamps.
Endpoint: GET /contacts/:contactId/notes
Key fields: notesId, contactId, content, date
Trigger: Loyalty events or appointments in Loyalzoo trigger calendar sync in GHL.
Actions: Create/update appointments in GHL; fetch appointment details; mark completed when done.
Endpoint: GET /contacts/:contactId/appointments
Key fields: appointmentId, date, time, location
Real-time, bidirectional data sync keeps contact records accurate across Loyalzoo and GHL without manual updates.
Automated triggers let you run workflows in Loyalzoo or GHL when data changes, reducing friction.
Scalability and extensibility allow you to build complex automations as your needs grow.
Key elements include API endpoints, authentication, request and response formats, and error handling. Use consistent naming and versioning for maintainability.
Application Programming Interface: a defined set of rules that lets different software entities talk to each other.
A specific URL path and HTTP method that performs a particular operation on the API, such as retrieving a contact or posting a note.
A standard protocol for secure authorization that lets apps access user data without exposing passwords.
A callback URL that the API calls when certain events occur, enabling near real-time updates.
Automatically create Loyalzoo contacts in GHL when a new user signs up in Loyalzoo, and populate key fields from the welcome data.
Link loyalty redemptions and points to contact activity in GHL for a complete customer history.
Schedule batch syncs to keep large contact lists aligned and generate cross-platform reports.
Generate a client ID and secret, assign the contacts.readonly scope, and save securely.
Define the data you want to sync, map fields between Loyalzoo and GHL, and set up webhooks if supported.
Run tests, confirm data integrity, and deploy to production with monitoring.
Use OAuth2 or API keys as supported by GHL. Keep credentials secure and refresh tokens regularly. For production, prefer OAuth with scoped access and implement least-privilege permissions. Test in a sandbox before going live.
Identify the core endpoints you’ll use (contacts, notes, tasks, and appointments). Start with read-only access to validate data flows, then expand to write operations if needed. Leverage webhooks for near real-time updates.
Yes. Loyalzoo can trigger automations in GHL by creating or updating resources, and GHL can respond with actions via webhooks or API calls depending on configuration.
Expect per-minute or per-second rate limits based on your GHL plan. Implement retry logic with exponential backoff and monitor API usage in the dashboard.
A basic understanding of REST APIs and authentication helps. No heavy coding required thanks to no-code or low-code options, but some setup is needed for field mappings and workflows.
Check error messages, verify credentials, and test each endpoint with sample data. Use sandbox environments and implement logging to identify where failures occur.
Consult the official GHL API docs for endpoints, schemas, and versioning. Use versioned endpoints and keep integrations up-to-date with changes.
Due to high volume, we will be upgrading our server soon!
