The Contacts API uses API keys and OAuth-style tokens. In Zapier, configure authentication by selecting the Contacts API connector, entering your credentials, and granting access to read contact data within the defined scope: contacts.readonly.
Zapier App Connector authenticates to GHL using OAuth or API key-based methods. Follow the app’s connection flow to securely store tokens and manage permissions for the Contacts API.
This integration exposes a core set of endpoints to read and manage contacts, tasks, notes, and appointments. Use GET to retrieve data, POST to create, PUT to update, and DELETE to remove resources. Endpoints include: 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: when a specific contact is retrieved or changes in GHL.
Actions: pull basic contact data, plus related items like tasks, notes, and appointments for that contact.
GET /contacts/:contactId
contactId, name, email, phone, company, lastModified
Trigger: when a contact’s tasks are requested in a workflow.
Actions: list tasks, filter by status, or create new tasks for the contact.
GET /contacts/:contactId/tasks
taskId, contactId, title, dueDate, status
Trigger: retrieve a single task when needed for a workflow.
Actions: fetch a single task, update details, or mark as completed.
GET /contacts/:contactId/tasks/:taskId
taskId, contactId, title, status, dueDate

Answer: The Contacts API provides the data you access from GHL, while the Zapier App Connector is the automation layer that runs workflows across apps. In short, you read contact data from GHL and act on it in other apps through Zapier. The integration organizes data flow so you can trigger actions and receive updates without writing code.
Answer: No heavy coding is required. You configure triggers and actions within the Zapier UI using the provided endpoints. Some basic field mapping may be needed to align your GHL data with your app fields. If you need to modify write permissions, adjust the authentication scope accordingly.
Answer: The integration exposes a core set of endpoints for reading and writing contacts, tasks, notes, and appointments, including 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. Use the endpoints that fit your workflow and ensure proper authentication.
Answer: Authentication typically uses OAuth tokens or API keys. In Zapier, set up a secure connection for the Contacts API, grant the defined scope (e.g., contacts.readonly or more), and refresh tokens as needed. Permissions determine which data you can read or modify within workflows.
Answer: Yes. You can automate updates to notes and tasks by triggering on contact changes or note creation and then performing corresponding actions (update task status, create notes, etc.). The endpoints support bulk and individual operations you can chain in multi-step Zapier workflows.
Answer: Use Zapier’s test mode to simulate runs with sample data, review task history, and adjust mappings. Validate API responses, handle errors gracefully, and progressively enable live runs after successful tests.
Answer: Starter templates and example workflows are available within Zapier and the GHL integration docs. Look for templates that map to contact creation, task assignment, and note synchronization to speed up setup.
