Authenticate requests to the GHL Contacts API using your API key or OAuth token. Include the token in the Authorization header for each call and scope access to only the required resources.
Authenticate the Zapier App Connector using OAuth 2.0 and securely stored credentials. When possible, limit scopes to contacts.readonly unless write operations are needed.
Common 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. API scope: contacts.write for write operations; endpoints 1–7 cover reads; endpoints 9–17 cover writes and management.
Trigger: retrieve a specific contact to pull its data into Zapier for downstream actions.
Actions: Get contact details, Update contact, List tasks, Create task, List notes, Create note, Tag a contact.
GET /contacts/:contactId
contactId, name, email, phone
Trigger: when a business’s contacts need synchronization
Actions: List contacts by business, Create or update multiple contacts, Filter by tag
GET /contacts/business/:businessId
businessId, contactId, name
Trigger: new or updated notes or tasks for a contact
Actions: List notes, List tasks, Create note, Create task, Update task status
GET /contacts/:contactId/notes
contactId, noteId, taskId
Automate repetitive contact updates without writing code.
Create multi-step automations across apps with simple triggers and actions.
Keep contact data synchronized and accurate across platforms in real time.
Key elements include endpoints, authentication, data mapping, and workflow automation.
Application Programming Interface: a set of rules that lets software applications communicate and request data.
The process of verifying identity to access APIs and data.
A specific URL path in an API used to perform a function and return data.
A mechanism for apps to receive real-time updates when events occur.
Capture new leads from a form and push them into GHL Contacts, creating or updating as needed.
Create tasks in your project tool when tasks are assigned in GHL, and keep statuses updated.
Automatically push important email threads as notes on the corresponding contact in GHL.
In your GHL account, generate an API key with at least readonly scope and store securely.
Create a new Zapier integration, select GHL Contacts API, and authenticate using the API key or OAuth.
Run tests to verify data mapping, then switch to live mode.
GHL supports authentication via API keys or OAuth tokens. To securely access the Contacts API, generate a private API key from your GHL developer settings and include it in the Authorization header as a Bearer token. If you prefer OAuth, set up a standard OAuth 2.0 flow and refresh tokens automatically in Zapier, ensuring your scopes are limited to the resources your workflow needs.
Common endpoints for syncing include retrieving a single contact (GET /contacts/:contactId), listing a contact’s tasks (GET /contacts/:contactId/tasks), notes (GET /contacts/:contactId/notes), and appointments (GET /contacts/:contactId/appointments). You can also create or update contacts (POST /contacts/, PUT /contacts/:contactId) and manage tasks (POST/PUT/DELETE /contacts/:contactId/tasks/:taskId). Map the data you fetch to your app fields to maintain consistency across systems.
Yes. Zapier App Connector can perform create and update operations against the GHL Contacts API using endpoints such as POST /contacts/ and PUT /contacts/:contactId. Build Zaps that trigger on your chosen events and map fields accordingly to keep data in sync.
Field mapping is done in Zapier during the setup of your Zap. Map GHL fields like name, email, and phone to corresponding fields in your app, and use derived fields or computed values where needed. Validate mappings with test data to ensure accuracy before going live.
Be mindful of API rate limits and apply best practices such as batching updates, retry logic with exponential backoff, and handling partial failures gracefully. Use webhooks where supported to reduce polling and improve efficiency.
Implement error handling by capturing API response codes, logging errors, and configuring Zapier retries. For transient errors, allow automatic retries; for persistent issues, alert your team and pause the Zap until resolution.
If a contact is deleted in GHL, your Zap should handle this gracefully. Depending on your workflow, you may remove the corresponding record in your app or mark it as inactive. Consider implementing soft delete and audit trails to preserve historical data.
