Authenticate requests to the GHL Contacts API with your API key or OAuth token. Use secure storage, rotate credentials regularly, and test in a sandbox before going live.
FareHarbor requires an API key or OAuth token for third party integrations. Generate credentials in FareHarbor developer settings and keep them secret.
GET /contacts/:contactId — Retrieve a single contact; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task; GET /contacts/:contactId/notes — List notes for a contact; GET /contacts/:contactId/notes/:id — Retrieve a single note; GET /contacts/:contactId/appointments — List appointments for a contact; GET /contacts/ — List all contacts; GET /contacts/business/:businessId — List contacts for a business; contacts.write — Permission scope; POST /contacts/ — Create a new contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; POST /contacts/:contactId/tasks — Create a task for a contact; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task as completed; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Add tags to a contact
Trigger: a new or updated FareHarbor contact is created
Action: upsert the corresponding contact in GHL using POST /contacts/ or PUT /contacts/:contactId
POST /contacts/ OR PUT /contacts/:contactId
contactId, email, firstName, lastName, phone
Trigger: a FareHarbor appointment is created or updated
Actions: create or update a GHL task linked to the contact
POST /contacts/:contactId/tasks
contactId, appointmentId, summary, dueDate
Trigger: a note is added in FareHarbor for a contact
Actions: create a note in GHL for the related contact
POST /contacts/:contactId/notes
contactId, noteId, content
Leverage no‑code automation to sync contacts, tasks, and notes between systems without writing code
Real‑time updates reduce duplicate data and manual data entry
Easier onboarding with a clear data map and automated error handling
Key terms used in these pages include API, authentication, endpoints, webhooks, and data mapping to help you understand how GHL Contacts API and FareHarbor work together
Application Programming Interface: a set of rules that allow two apps to communicate and exchange data
A real-time HTTP callback that notifies another app when an event occurs
Verification of identity to access an API, typically via API keys or OAuth tokens
A specific URL and HTTP method used to interact with a resource in an API
When a new FareHarbor booking is created, push a contact into GHL with core details like name, email, and booking ID
If a GHL contact is updated, add a note in FareHarbor describing the change to keep both records aligned
Link FareHarbor appointments to the corresponding GHL contact to view history in one place
Obtain GHL API keys with the right scope (contacts.readonly) and generate FareHarbor API credentials; store them securely
Define which fields map to each other (name, email, phone, booking ID) and establish unique identifiers for upsert operations
Run sandbox tests, enable webhooks, review error logs, and then deploy to production
No code is required to start. You can use a no‑code automation platform or the Zapier App Connector to set up triggers and actions between FareHarbor and GHL. Begin with the essential endpoints and gradually expand as you validate the workflow. If you prefer, you can also implement a custom middleware for more complex mappings.
Key endpoints include GET /contacts/:contactId for retrieving a contact, POST /contacts/ to create, and PUT /contacts/:contactId to update. For tasks, notes, and appointments, use the respective endpoints to keep data synchronized across systems. Establish a clear mapping for fields like contactId, email, and booking identifiers.
Data is protected by API authentication and encrypted transport. Use least-privilege credentials, rotate keys regularly, and monitor access logs. Both systems support webhook notifications so you can verify event integrity.
Yes. Use a sandbox or development environment to simulate bookings, contact creation, and updates. Validate each flow step by step and review error messages before moving to production.
Check the logs for failed endpoints, verify authentication, and confirm field mappings. If needed, re-run the sync with adjusted parameters and retry the operation. Implement retries and alerting to minimize data drift.
Real-time via webhooks is possible, but you can also schedule periodic syncs. Real-time gives faster updates; periodic syncs provide a simpler, more predictable flow for high-volume data.
API credentials are generated in the FareHarbor developer section and in the GHL admin panel. Keep credentials secure, and reference documentation for the exact scopes required for your integration.
Due to high volume, we will be upgrading our server soon!
