Use your GHL API key and the configured scope to authorize requests to the Contacts API. Scope: contacts.readonly.
Grant the necessary permissions to allow GHL to access and update data in Firebase – Firestore, following your security policy.
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; contacts.write; 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
Trigger: Fetch a contact’s profile and its tasks from Firestore to keep GHL in sync.
Actions: GET /contacts/:contactId to fetch contact; GET /contacts/:contactId/tasks to fetch tasks; GET /contacts/:contactId/notes to fetch notes.
GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/notes
contactId, name, email, phone, taskId, status, notes
Trigger: A new or updated contact in GHL creates or updates the corresponding Firestore document.
Actions: POST /contacts/ to create; PUT /contacts/:contactId to update; POST /contacts/:contactId/tasks to create tasks; PUT /contacts/:contactId/tasks/:taskId to update tasks.
POST /contacts/; PUT /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId
contactId, name, email, businessId, taskId, status, notes
Trigger: When a contact is removed in GHL, delete the corresponding Firestore documents.
Actions: DELETE /contacts/:contactId; DELETE /contacts/:contactId/tasks/:taskId
DELETE /contacts/:contactId; DELETE /contacts/:contactId/tasks/:taskId
contactId, taskId
No-code integration speeds up setup and data syncing between GHL and Firestore without writing custom code.
Automations run in the background, keeping data current across platforms.
Provides audit trails, retries, and scalable data flows.
Overview of the elements and processes used to connect the GHL Contacts API with Firebase – Firestore, including endpoints, auth, data mapping, and error handling.
A specific URL or path exposed by an API that allows a client to access data or perform actions.
Verifying identity and granting permissions to access API resources.
An authorization framework that enables secure delegated access to user data.
Firebase’s NoSQL document database for storing and syncing data in real time.
When a new contact is created in GHL, automatically create a Firestore document with core fields.
Update Firestore notes and tasks as they evolve in GHL.
Store change history in a dedicated Firestore collection for accountability.
Obtain a GHL API key and configure the scope for contacts.readonly before enabling write access.
Map GHL contact fields to Firestore fields and decide on identifiers like contactId.
Run end-to-end tests, verify error handling, and monitor logs before going live.
The Contacts API exposes a range of endpoints such as retrieving a contact, its tasks, notes, and appointments, as well as creating, updating, and deleting records. These endpoints allow you to fetch data from GHL and push or pull information to/from Firebase – Firestore. Use the endpoints in combination with the provided triggers and actions to build no-code automations that keep your Firestore documents aligned with GHL contacts.
Security is handled with OAuth scopes and API keys. The scope shown is contacts.readonly, which can be expanded as needed with proper configuration. Rate limits depend on your account and plan; design your flows with retries and backoff.
Yes, you can write data back to Firestore via endpoints like POST /contacts/ and PUT /contacts/:contactId, as well as related task endpoints. Ensure your rules allow writes and implement validation to avoid data conflicts.
No extensive coding is required; you can configure the integration with no-code tools and the Zapier App Connector. For advanced mappings, you may use minimal custom code or cloud functions if needed.
Real-time syncing is possible using triggers and polling strategies; depending on the platform, you can implement real-time updates. In practice, you may set up webhooks or near real-time polling.
Errors are surfaced in logs; common issues include permission errors and mismatched field types. Retries with exponential backoff are recommended; set up alerting to respond quickly.
You can review data mappings and endpoints in the integration guide and in your GHL account settings. The Endpoints list shows all available REST paths; use the API docs for detailed field definitions.
Due to high volume, we will be upgrading our server soon!
