Authenticate with the Contacts API using OAuth 2.0 or API keys. The required scope for read operations is contacts.readonly; for write operations include contacts.write as needed.
In Zapier, configure OAuth 2.0 credentials or API key setup for the GHL Contacts API, and securely store tokens with automatic refresh where supported.
Endpoints include:\n- GET /contacts/:contactId\n- GET /contacts/:contactId/tasks\n- GET /contacts/:contactId/tasks/:taskId\n- GET /contacts/:contactId/notes\n- GET /contacts/:contactId/notes/:id\n- GET /contacts/:contactId/appointments\n- GET /contacts/\n- GET /contacts/business/:businessId\n- WRITE permissions: contacts.write\n- POST /contacts/\n- PUT /contacts/:contactId\n- DELETE /contacts/:contactId\n- POST /contacts/:contactId/tasks\n- PUT /contacts/:contactId/tasks/:taskId\n- PUT /contacts/:contactId/tasks/:taskId/completed\n- DELETE /contacts/:contactId/tasks/:taskId\n- POST /contacts/:contactId/tags
Trigger: A new contact is created in GHL (or an existing contact is updated). Zapier starts a workflow.
Actions: Create a follow-up task for the contact, set due date, and assign to the owner.
POST /contacts/:contactId/tasks
contactId, taskTitle, dueDate, assigneeId
Trigger: Contact is updated in GHL
Actions: Add or update notes for the contact, optionally update related fields.
PUT /contacts/:contactId
contactId, notes, customFields
Trigger: Tasks for a contact change state
Actions: Get tasks, filter by status, export to a spreadsheet or dashboard.
GET /contacts/:contactId/tasks
contactId, status
Build powerful automations without writing a line of code using triggers and actions in Zapier.
Achieve real-time data synchronization between GHL and other apps with minimal setup.
Leverage a wide set of endpoints to tailor CRM workflows to your business.
Definitions of endpoints, triggers, actions, and fields used in the GHL Contacts API and Zapier integration.
The API within GHL that manages contacts, tasks, notes, and appointments programmatically.
A standard authorization framework used to securely grant access to APIs without sharing passwords.
A specific URL path and HTTP method used to access a resource in an API.
Automations built in no-code tools like Zapier to connect apps and automate tasks.
When a new contact is added in GHL, automatically create a follow-up task and assign it to the appropriate teammate.
Capture form submissions from other apps and append notes to the corresponding GHL contact record.
Automatically tag or update contact status in GHL when events occur in your marketing automation tool.
Generate a client ID/secret or API key in GHL and specify the scopes you need (contacts.readonly for reads; contacts.write for writes).
In Zapier, choose the GHL Contacts API app, connect using your credentials, and map triggers and actions to endpoints.
Create Zaps that respond to new or updated contacts and perform tasks, notes, or other actions using the available endpoints.
No coding is required. Zapier App Connector provides a visual interface to set up triggers, actions, and data mapping for the GHL Contacts API. You can automate workflows without writing code. In addition, you can reuse templates and sample data to validate your setup.\nIf you ever need more advanced logic, you can combine multiple steps, filters, and paths within Zapier to achieve complex flows.
Common endpoints for automation include GET /contacts/:contactId to fetch data, GET /contacts/:contactId/tasks to retrieve tasks, POST /contacts/:contactId/tasks to create tasks, PUT /contacts/:contactId to update a contact, and POST /contacts/:contactId/tags to add tags. For read-only automations, use the readonly scope; for write automation, ensure the appropriate write scope (contacts.write) is granted.\nTest each step with sample data and monitor the Zap history for troubleshooting.
Secure authentication is supported via OAuth 2.0 or API keys. Use OAuth 2.0 when possible and rotate tokens regularly. Store credentials securely in Zapier and use refresh tokens where provided. If you use API keys, keep them secret and avoid embedding them in client-side code.\nAlways scope requests to the minimum required permissions (e.g., contacts.readonly for reading data).
Yes, you can write to the API where permitted. Endpoints like POST /contacts/, POST /contacts/:contactId/tasks, and POST /contacts/:contactId/tags support creating or modifying data. Ensure your credentials include the required scopes (example: contacts.write) and test operations in a controlled environment.\nUse error handling in Zapier to gracefully manage failures and retries.
GET endpoints let you fetch contact data, tasks, notes, and appointments. You can pull fields such as contact properties, associated tasks, notes content, and appointment details to power dashboards and reports. The exact fields available depend on your GHL configuration and API version.\nFilter responses with query parameters when supported to minimize data transfer.
Error handling includes checking HTTP status codes, parsing error messages, and implementing retries with backoff. Be mindful of API rate limits and space out requests accordingly. Use Zapier’s built-in tools to pause or rerun failed steps and notify your team if needed.\nAlways validate your payloads with test data before deploying automations.
Endpoint examples are available in the official documentation and within the Zapier GHL app guide. You can also view sample zaps and templates within Zapier’s app directory to see practical implementations.\nExperiment with sandbox/test accounts to learn how data flows between GHL and connected apps.
Due to high volume, we will be upgrading our server soon!
