Authenticate requests with your GHL API key or OAuth token to secure data exchange between Zapier and Contacts API. Treat credentials as sensitive and rotate them periodically.
Connect Zapier to your GHL account by creating a connection in Zapier and selecting the Contacts API scope. Test the connection to confirm credentials are working.
– 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
Trigger: A new contact is added in your source system, prompting Zapier to create a contact in GHL using POST /contacts/.
Actions: Map essential fields (name, email, phone, company) and create initial tasks if needed using POST /contacts/:contactId/tasks.
POST /contacts/
name, email, phone, company
Trigger: Updated data in your source app updates the corresponding GHL contact.
Actions: Use PUT /contacts/:contactId to apply updates; optionally adjust related notes or tasks via their endpoints.
PUT /contacts/:contactId
contactId, updates (name/email/phone)
Trigger: When a contact changes, fetch and sync related tasks and notes to keep all systems aligned.
Actions: GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to pull data and push into downstream apps.
GET /contacts/:contactId/tasks
contactId, taskNotesFields
Automate repetitive contact workflows without writing code.
Keep your data in sync across tools with real-time or scheduled Zaps.
Easily map fields and create powerful automations using a visual Zapier builder.
This section outlines the core terms and processes used in the integration: endpoints, triggers, actions, and data fields.
Application Programming Interface — a set of rules that lets apps talk to one another.
A specific URL path in an API used to access a resource or perform an action.
An event in one app that starts a Zapier workflow.
An operation performed in response to a trigger, such as creating or updating a record.
Capture new leads in your form tool and automatically create a GHL contact via POST /contacts/ when the form submits.
When a contact is created or updated, Zapier can auto-create or update onboarding tasks using POST /contacts/:contactId/tasks.
Sync notes and tags with each contact to maintain contextual data across systems via GET/POST endpoints.
Gather your GHL API key and set up the Zapier app connection, selecting the Contacts API scope.
Choose triggers such as New or Updated Contact and map fields accordingly.
Create Zaps to automate actions and test end-to-end with sample data.
The Contacts API scope shown here is readonly by default, which allows you to retrieve data like contacts and their activities. To perform writes, request additional scope or use the endpoints specifically designed for creation and updates. For best results, pair with Zapier triggers and actions that align to your workflow, ensuring you handle error responses gracefully and log activity for auditing.
You do not need to write code to connect. The Zapier App Connector provides a visual builder to map fields and define triggers and actions. However, some familiarity with your data model helps you set up clean mappings and robust error handling.
Commonly used endpoints include POST /contacts/ for creation, PUT /contacts/:contactId for updates, and GET /contacts/:contactId/tasks for related tasks. Depending on your use case, you may also pull notes, appointments, and tags to enrich your workflows.
Authenticating securely starts with using API keys or OAuth tokens issued by GHL and kept in Zapier’s credential store. Rotate keys regularly, and never expose credentials in shared logs or public docs; use Zapier’s test/connection features to validate.
Yes. You can fetch tasks and notes for a contact using GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes. This enables task reminders, notes capture, and context sharing across apps in your automation.
Yes. You can create new contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. Map fields in Zapier to the GHL data model and test thoroughly to avoid partial updates or data mismatches.
Zapier’s test connect feature validates credentials and endpoints against your GHL account. You can also run live tests in a sandbox or with a limited dataset to confirm expected behavior before going to production.
Due to high volume, we will be upgrading our server soon!
