The Contacts API uses OAuth 2.0 for secure access. Obtain client credentials, request access tokens, and refresh tokens as needed when connecting through the Zapier App Connector.
In Zapier, create a connected account to authorize access to the Contacts API. Follow prompts to authorize and grant the required scopes (e.g., contacts.readonly).

Trigger: A contact is created or updated. The workflow fetches the contact’s details, then pulls related tasks, notes, and appointments to keep systems in sync.
Actions: GET /contacts/:contactId to retrieve the core contact record; GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to pull related data; optionally GET /contacts/:contactId/appointments for calendar context.
GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/notes; GET /contacts/:contactId/appointments
Key fields: contactId, name, email, phone, businessId, notes, tasks
Trigger: A new or updated contact is detected. The workflow ensures the contact exists in all systems and creates related tasks as needed.
Actions: POST /contacts/ to create, or PUT /contacts/:contactId to update; then POST /contacts/:contactId/tasks to create initial follow-up tasks.
POST /contacts/; PUT /contacts/:contactId; POST /contacts/:contactId/tasks
Fields: contactId, name, email, phone, status, createdAt; task fields include taskId, title, dueDate, status
Trigger: A note or appointment is added or updated for a contact. The integration mirrors these changes across connected apps.
Actions: GET /contacts/:contactId/notes; POST /contacts/:contactId/notes; GET /contacts/:contactId/appointments; POST /contacts/:contactId/appointments.
GET /contacts/:contactId/notes; POST /contacts/:contactId/notes; GET /contacts/:contactId/appointments; POST /contacts/:contactId/appointments
Fields: contactId, noteId, appointmentId, content, date
No-code automation lets you connect data across GHL and your apps quickly without writing custom code.
Rapid deployment enables teams to automate repetitive tasks, improving accuracy and efficiency.
Centralized data movement reduces gaps between systems and provides a single source of truth.
This glossary explains core terms and how data moves between GHL and the Zapier App Connector during a typical workflow.
A person entry in the Contacts API containing fields such as id, name, email, phone, and businessId.
A scheduled event linked to a contact, used to plan meetings or calls within workflows.
A unit of work associated with a contact (for example, a follow-up call or email task).
A text entry attached to a contact to capture context, history, or notes from interactions.
Trigger when a new contact is created, inspect the email domain, automatically assign a tag, and notify the sales team.
When a contact task is created in GHL, create a corresponding task in your project management tool via the App Connector, keeping status in sync.
Detect lifecycle progression and automatically schedule follow-up appointments, reducing churn and improving engagement.
Create a new connected account in Zapier and store the client ID and client secret for the Contacts API.
Choose the supported endpoints, map API response fields to Zapier fields, and set up triggers and actions.
Run tests with sample data, verify data flow, and enable the automation in production.
Yes. To access the Contacts API through the Zapier App Connector you must authenticate the connection. This involves obtaining an OAuth 2.0 token and granting the app the necessary scope (e.g., contacts.readonly) so triggers and actions can read contact data. After authorization, Zapier will securely store the access token for automatic refreshes. Once connected, you can configure triggers and actions that read contact details, ensuring your automation stays in sync with your GHL data without manual credential handling.
Read-only endpoints include retrieving a contact and its related data (tasks, notes, appointments) and listing contacts. You can use GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments to surface information without making writes. If you need writable access, you can request additional scopes (like contacts.write) and enable endpoints for creating or updating records within Zapier.
Yes. The Zapier App Connector supports creating and updating contacts via POST /contacts/ and PUT /contacts/:contactId. You can attach related data such as tasks (POST /contacts/:contactId/tasks) in the same workflow. Map fields from your source apps to the Contacts API fields, and use subsequent actions to manage tasks, notes, or appointments as part of the same automation.
Common errors include authentication failures, missing required fields, and rate limits. Use Zapier’s built-in retry logic and exponential backoff. For API errors, check the response status and error messages, then adjust field mappings or add conditional paths to prevent repeated failures. Enable logging in both GHL and Zapier to monitor failed executions and quickly diagnose issues.
Key contact fields typically include contactId, name, email, phone, and businessId, plus custom fields you’ve added in GHL. Depending on your integration, you may also access related data like tasks, notes, and appointments to enrich contact records. Use field mappings to ensure downstream apps receive consistent data types and formats.
To connect multiple apps, create a single Zapier connection to the Contacts API and then add multiple Zaps or workflows that interact with different apps. You can route data to CRMs, task managers, calendars, and marketing tools, all while keeping the source data synchronized via the same OAuth connection. Leverage shared triggers to minimize API calls and maintain consistency across workflows.
Usage, limits, and logs are viewable in both GHL API documentation and Zapier task history. Monitor the number of API calls, watch for rate limit messages, and review failed runs in Zapier. Consider batching requests and using conditional logic to keep usage within quotas. For long-running automations, use built-in retries and backoff strategies to ensure reliability.
Due to high volume, we will be upgrading our server soon!
