Use OAuth 2.0 where supported or generate a secure API key to authorize requests. Ensure your account has the required scopes (contacts.readonly) for read operations and configure write permissions if you need to modify data.
In Zapier, configure OAuth 2.0 or API token flow to securely connect to GHL’s Contacts API. Follow guided prompts to authorize access and test the connection
– 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 Permissions: contacts.readonly, contacts.write
Trigger: when a contact is created or updated in GHL, push the data to your app to create or refresh a customer record.
Actions: upsert the corresponding contact in Zapier App Connector, then run downstream automations like onboarding tasks or email nurture.
Common methods include POST /contacts/ to create and PUT /contacts/:contactId to update existing records.
Key fields: id, email, firstName, lastName
Trigger: a new or updated contact task in GHL should appear as a task in the connected app.
Actions: create or update tasks in the app, map status, due dates, and assignees automatically.
Methods: POST /contacts/:contactId/tasks to add tasks; PUT /contacts/:contactId/tasks/:taskId to update.
Key fields: taskId, contactId, title, dueDate
Trigger: notes added or updated on a contact in GHL.
Actions: create or update notes in the app and optionally post a message to a channel or log activity.
Methods: POST /contacts/:contactId/notes; PUT /contacts/:contactId/notes/:id
Key fields: noteId, contactId, content
Build powerful automations fast without writing code.
Keep data consistent across GHL and your apps with centralized mappings.
Scale workflows easily with retries, error handling, and monitoring.
This glossary covers core concepts used throughout this guide: endpoints, triggers, actions, field mappings, and data objects.
A specific URL and HTTP method that performs an action on the GHL Contacts API.
An authorization framework that grants limited access to resources without sharing user credentials.
A URL that receives real‑time notifications when events occur in an integrated app.
The maximum number of API requests allowed in a defined time window.
When a new contact is created in GHL, automatically create a lead in your app and start onboarding tasks.
Map contact changes to tasks or issues in your PM tool to keep teams aligned.
Post real‑time updates to Slack or Teams when notes or tasks are updated.
Choose the Contacts API in GHL and the Zapier App Connector, then authorize access with the required scopes.
Select the endpoint data to sync, map fields, and set up automation logic.
Run tests to verify data flow, then enable the automation in your workflow.
The Contacts API exposes endpoints to read and manage contacts, tasks, notes, and appointments. For example, GET /contacts/:contactId retrieves a specific contact, while GET /contacts/ returns a list of contacts. You can combine these with task and note endpoints to build coordinated automations. If you need write access, you can employ POST, PUT, and DELETE methods like POST /contacts/ and PUT /contacts/:contactId to create or update data. Permissions can be scoped as read-only or allow writes depending on your configuration.
No‑code is a core benefit of the Zapier App Connector. You can connect the GHL Contacts API without writing code by configuring triggers, actions, and field mappings through the UI. Some setups may require enabling write scopes (contacts.write) to modify data.
Authentication typically uses OAuth 2.0 or API keys. In most cases, you’ll authorize the GHL Contacts API within Zapier, select the relevant scopes, and test the connection. This keeps credentials secure while enabling automated data flow.
Yes. You can create new contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. You can also manage related data like tasks and notes by using their respective endpoints.
The API enforces rate limits to protect service reliability. When building automations, stagger requests, batch operations when possible, and implement retries to handle transient limits gracefully.
GHL and Zapier support secure communications over HTTPS, with token-based authentication and scope management. Ensure you follow best practices for credentials storage and grant only the minimum necessary access.
Field mapping lets you align data between GHL and your app. In triggers and actions, select source fields (e.g., contact.name, contact.email) and map them to destination fields in your app to ensure data consistency.
Due to high volume, we will be upgrading our server soon!
