To use the Contacts API with the Zapier App Connector, start with secure access through OAuth scopes such as contacts.readonly and required write permissions. Store tokens securely and refresh as needed.
In Zapier, configure OAuth or an API key for the Zapier App Connector to access Contacts API. Select the provided scopes and reauthorize if access is revoked.
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; contacts.write; 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 or an existing contact is updated in Contacts API, then the Zapier App Connector upserts the corresponding contact in your system.
Actions: Upsert contact data, sync related tasks and notes, and apply tags as needed.
Method Path: POST /contacts/ for new contacts; PUT /contacts/:contactId for updates.
Key fields: contactId, name, email, phone, ownerId
Trigger: Task creation, update, or completion under a contact.
Actions: Create, update, or complete tasks via /contacts/:contactId/tasks and /contacts/:contactId/tasks/:taskId.
Method Path: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; DELETE /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed
Key fields: contactId, taskId, status, dueDate
Trigger: Notes added or updated on a contact; tags added or removed.
Actions: Create notes, update notes, attach tags and associate notes with the contact.
Method Path: POST /contacts/:contactId/notes; POST /contacts/:contactId/tags
Key fields: contactId, noteId, tagName
Build automated workflows in minutes without writing code.
Automate repetitive tasks and keep data in sync across systems.
Scale processes with reusable Zap templates as your team grows.
This section explains essential elements: API endpoints, authentication, data mapping, triggers, actions, and error handling to help you design reliable automations.
A person or CRM record with associated notes, tasks, appointments, and contact history.
A specific API URL and operation that performs a defined action.
A URL configured to receive real-time updates from an external system.
A secure framework for authorizing API access without sharing credentials.
When a new contact is added in Contacts API, automatically create a follow-up task in Zapier App Connector to nurture the lead.
Consolidate notes, tasks, and upcoming appointments into a single timeline in your CRM via Zapier.
Automatically tag or route contacts to teams based on activity, status, or field values.
Set up OAuth details and request the required scope (contacts.readonly) in Zapier.
Choose the Contacts API endpoints, map fields (name, email, phone), and set trigger conditions.
Run tests to validate data flow, error handling, and edge cases before going live.
No coding is required to connect Contacts API with the Zapier App Connector. You can create powerful automations using triggers, actions, and prebuilt templates. If you need more advanced logic, you can layer filters and conditional steps within Zapier to tailor the workflow to your needs. If you run into limitations, you can still design multi-step Zapier workflows that call multiple endpoints in sequence to achieve complex data synchronization without writing code.
The integration exposes key endpoints such as getting a contact by ID, listing a contact’s tasks, notes, and appointments, as well as creating or updating contacts and tasks. Use GET for reads, POST to create, PUT to update, and DELETE to remove items. In Zapier, you can select these endpoints as triggers or actions and map fields accordingly. Refer to the endpoint list in the Endpoint overview for the full set and usage notes.
Authentication is via OAuth or API key configured in the Zapier App Connector. You will authorize the app once, then Zapier will refresh tokens as needed. Ensure the access scope includes at least contacts.readonly for reads and additional write scopes for updates. Reauthorization may be required if credentials are revoked or expired.
Yes. You can update contacts and tasks from Zapier by using the appropriate PUT endpoints for contacts and tasks. For updates, ensure you pass the required fields (such as contactId or taskId) and validate response status. You can also delete records using the corresponding DELETE endpoints when needed.
Rate limits depend on your GHL plan and API usage. Plan for typical business workloads by batching requests where possible and using conditional logic in Zapier to minimize unnecessary calls. If you exceed limits, implement exponential backoff and retry strategies within Zapier workflows.
Common errors include invalid tokens, missing scopes, or incorrect field mappings. Check the Zapier app connection status, re-authenticate if needed, verify the endpoint URL and method, and review the field mapping in your Zap to ensure required fields are provided.
You can view logs and activity in the Zapier task history and, for deeper debugging, enable verbose logging in the Zapier app settings. If issues persist, consult the integration logs in your GHL account and contact support for assistance.
Due to high volume, we will be upgrading our server soon!
