Authenticate requests to the Contacts API using OAuth 2.0 with the required scope. Obtain client credentials from your GHL account and authorize the Zapier App Connector to access contact data.
The Zapier App Connector uses OAuth 2.0 client credentials to securely connect to the GHL Contacts API. Store tokens securely in your Zapier account and refresh as needed.

Trigger: A new contact is created or an existing contact is updated in GHL. This event starts a Zapier workflow to sync data to the Contacts API.
Action: Create or update the corresponding contact in the Contacts API to keep data in sync across platforms.
Methods: POST /contacts/ to create, PUT /contacts/:contactId to update.
name, email, phone, tags, custom fields
Trigger: A new task is created or updated for a contact in GHL.
Action: Create or update a task under the same contact in the Contacts API.
Methods: POST /contacts/:contactId/tasks to create, PUT /contacts/:contactId/tasks/:taskId to update.
contactId, taskId, title, status, dueDate
Trigger: A note is added or updated for a contact in GHL.
Action: Create or update the note for the same contact in the Contacts API.
Methods: POST /contacts/:contactId/notes to create, PUT /contacts/:contactId/notes/:id to update.
contactId, noteId, content, author
No-code automation: build powerful workflows without writing code.
Unified data sync between GHL Contacts and external apps via Zapier.
Flexible endpoint coverage for common CRM tasks (read and write).
This glossary explains terms used in the GHL Contacts API and Zapier integration, including endpoints, authentication, and data mapping.
Application Programming Interface that allows your apps to communicate with the GHL Contacts data model.
Authorization framework that issues access tokens to grant limited access to your data securely.
Specific URLs in the API that perform actions like read, create, update, or delete resources.
Maximum number of API calls allowed in a given time window to protect the service from overuse.
Automatically create or update a contact in the Contacts API when a new lead is captured via forms, landing pages, or newsletters fed through Zapier.
Mirror new or updated tasks and notes between GHL and the Contacts API to keep team members aligned in real time.
Capture a history of changes by logging edits from GHL into the Contacts API via Zapier for compliance and reporting.
Authorize the Zapier App Connector to access your GHL Contacts data using OAuth 2.0 and select the contacts.readonly scope (adjust scopes as needed for write access).
Match GHL contact fields to the Contacts API fields in Zapier, and configure the triggers and actions for endpoints you plan to use.
Run test workflows, review logs, and enable the automation for ongoing operations.
The integration uses the contacts.readonly scope by default to safely read contact data. If you need write access, additional scopes must be granted and securely configured. Always follow least-privilege principles when assigning scopes. Paragraph two covers securing tokens and managing refresh cycles for long-running automations.
No coding is required for most workflows when using the Zapier App Connector. You can configure triggers, actions, and field mappings with a visual editor. If you need advanced logic, you can add conditional steps and filters within Zapier. Paragraph two reinforces best practices for testing and monitoring.
Yes. You can chain multiple endpoints in a single Zap or across multiple Zaps to build complex workflows. Paragraph two suggests planning data flow and avoiding duplicate writes by using upsert-style operations where available.
Authentication is handled via OAuth 2.0. You will authorize both systems and store tokens securely in Zapier. Paragraph two covers token refresh and expiration handling to keep connections seamless.
Read operations include endpoints like GET /contacts/:contactId and GET /contacts/:contactId/tasks. Write operations include POST /contacts/ and PUT /contacts/:contactId. Paragraph two explains when to use each type of endpoint and how to map fields.
There are standard API rate limits to prevent abuse. Implement backoff and retry logic in long-running automations. Paragraph two provides practical tips for pacing calls and monitoring usage.
Endpoint details and field mappings are documented in the integration guide and within Zapier’s setup screens. Paragraph two advises checking the endpoint list and using sample payloads to validate mappings.
Due to high volume, we will be upgrading our server soon!
