Access to the Contacts API requires proper authentication. Use OAuth 2.0 tokens scoped to contacts.readonly for read operations and contacts.write for write operations. Rotate credentials regularly and store them securely in Zapier’s connected app settings.
Configure OAuth 2.0 (recommended) or API key-based authentication in Zapier to securely connect to the GHL Contacts API. Ensure the app’s credentials are stored securely and permissions are limited to the necessary scopes.
Key endpoints you’ll commonly use include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, and endpoints for notes, appointments, and tags. Use these to build robust workflows in Zapier.
Trigger: A new or updated contact in GHL triggers a Zap to create or update a record in your CRM, funneling data consistently.
Actions: Create or update CRM contact, assign tasks, update notes, and tag as needed.
Endpoint paths involved: GET /contacts/:contactId and POST /contacts/ or PUT /contacts/:contactId
contactId, email, firstName, lastName, status, updatedAt
Trigger: Contact update or new note creates a task in the task management system
Actions: Create/update tasks via POST /contacts/:contactId/tasks, mark as completed with PUT /contacts/:contactId/tasks/:taskId/completed
POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId
contactId, taskId, title, status, dueDate
Trigger: Tag changes or notes updates on a contact to reflect in downstream systems
Actions: POST /contacts/:contactId/tags, POST /contacts/:contactId/notes, update notes via PUT /contacts/:contactId/notes/:id
POST /contacts/:contactId/tags, POST /contacts/:contactId/notes
contactId, noteId, tagNames
No-code automation at your fingertips: build complex workflows without writing code.
Time savings and accuracy from automated data syncing across apps.
Scalable workflows that adapt to your growing contact data and business needs.
Familiar terms and core processes you’ll encounter when using the GHL Contacts API with Zapier App Connector.
API stands for Application Programming Interface. It’s a set of rules that lets your apps talk to each other and request data or trigger actions securely.
OAuth 2.0 is a secure authorization framework used to grant limited access to your GHL data without sharing passwords.
An endpoint is a specific URL in an API that performs a function, such as retrieving a contact or updating a task.
A webhook is a real-time HTTP callback that notifies your system when something changes in GHL (e.g., a contact is updated).
Capture new form submissions, create or update a GHL contact, and trigger automatic follow-up tasks and emails via Zapier.
Prioritize tasks based on recent activity and automatically assign to the right team member.
Use GHL tags to segment contacts and trigger tailored nurture campaigns across tools.
Set up OAuth credentials in GHL and configure Zapier to accept them, ensuring the right scopes for read/write.
Choose the relevant endpoints (e.g., GET /contacts/:contactId, POST /contacts/) and map triggers in Zapier.
Create Zaps that perform actions like creating tasks, notes, or updating contacts based on events.
The Contacts API exposes endpoints to read and manage contact data, including profile fields, tasks, notes, appointments, and tags. Common reads include GET /contacts/:contactId and GET /contacts/:contactId/tasks. For write operations, you’ll use POST /contacts/ to create contacts, PUT /contacts/:contactId to update, and DELETE /contacts/:contactId to remove.
Authentication is handled via OAuth 2.0. Obtain an access token with the appropriate scopes (e.g., contacts.readonly for reads, contacts.write for writes). In Zapier, configure the connected app to use these tokens securely and refresh them as needed.
Yes. You can update a contact with PUT /contacts/:contactId, add notes with POST /contacts/:contactId/notes, and create or update tasks with POST /contacts/:contactId/tasks. Use the corresponding IDs to update or associate related resources.
No coding is required. The Zapier App Connector provides a no-code interface to map triggers and actions to GHL endpoints, allowing you to automate workflows through simple visual builders.
Rate limits depend on your GHL plan. Plan for bursts during peak automation, implement retries with exponential backoff, and design Zaps to batch requests when possible to avoid hitting limits.
Webhooks can notify your systems of changes in GHL in real time. You can configure webhooks to trigger Zapier workflows when a contact is updated, a note is added, or a tag changes, enabling immediate downstream actions.
API docs are provided in the GHL developer portal and the Zapier integration guide. They cover endpoint details, authentication, sample requests, and best practices for building reliable automations.
Due to high volume, we will be upgrading our server soon!
