Use your GHL credentials and OAuth tokens to securely authorize requests to the Contacts API endpoints listed below.
Connect Zapier App Connector to your GHL account using OAuth or API keys, then grant permissions to access Contacts data.
GET /contacts/:contactId — Retrieve a single contact GET /contacts/:contactId/tasks — List tasks for a contact GET /contacts/:contactId/tasks/:taskId — Get a specific task GET /contacts/:contactId/notes — List notes for a contact GET /contacts/:contactId/notes/:id — Get a specific note GET /contacts/:contactId/appointments — Retrieve appointments for a contact GET /contacts/ — List all contacts GET /contacts/business/:businessId — Get contacts by business contacts.write — Scope: write operations POST /contacts/ — Create a contact PUT /contacts/:contactId — Update a contact DELETE /contacts/:contactId — Delete a contact POST /contacts/:contactId/tasks — Create a contact task PUT /contacts/:contactId/tasks/:taskId — Update a task PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task complete DELETE /contacts/:contactId/tasks/:taskId — Delete a task POST /contacts/:contactId/tags — Add tags to a contact
Trigger on new or updated contacts from the Zapier App Connector, pushing changes to the Contacts API to keep data in sync.
Actions include creating or updating contact records, optionally creating related tasks or notes to reflect new information.
POST /contacts/ for create; PUT /contacts/:contactId for updates
contactId, email, firstName, lastName, phone
Trigger when related activity occurs in Zapier to add notes or tasks to a contact in GHL.
Actions include POST /contacts/:contactId/notes and POST /contacts/:contactId/tasks to enrich the contact data.
POST /contacts/:contactId/notes; POST /contacts/:contactId/tasks
contactId, noteId, taskId
Trigger when tags are updated in Zapier to reflect tag changes on the corresponding contact in GHL.
Actions include adding or removing tags via POST /contacts/:contactId/tags.
POST /contacts/:contactId/tags
contactId, tagName
No-code automation lets your teams connect data between Contacts API and Zapier without writing code, reducing time to value.
Pre-built triggers and actions enable rapid workflow creation and consistency across processes.
Scalability: easily extend automations as your data model grows.
Key elements include endpoints, authentication, webhooks, triggers, actions, and data mapping that empower no-code automations.
A specific URL and HTTP method exposed by an API that performs a defined operation, such as retrieving a contact or updating a task.
A standard authorization protocol that lets apps request limited access to user data without sharing credentials.
A method for servers to send real-time data to other applications when an event occurs.
The process of aligning fields between systems so data flows correctly between Zapier and the Contacts API.
Set up a Zapier flow that creates or updates Contacts API records as new leads enter your CRM, including tagging and task creation.
Automatically post meeting notes to a contact’s notes via the API when a calendar event is created.
Update contact tags based on actions in your CRM to keep segments current.
Obtain client credentials and authorize the Zapier App Connector to access Contacts API.
Select endpoints (e.g., GET /contacts/:contactId) and map fields between systems.
Create a test Zap, run through scenarios, and refine mappings for accuracy.
The Contacts API provides programmatic access to read and write contact data, tasks, notes, and more. When used with Zapier, you can automate data flows without code. Ensure your app’s OAuth scopes are configured to include readonly or write access as needed. This helps you keep contact information in sync across systems. If you encounter permission issues, verify that the Zapier App Connector has been granted the correct scopes and that your credentials are valid and not expired.
Yes. You typically need access to both the GHL account and the Zapier App Connector setup to authorize API usage. If you’re using a managed workspace, your admin may need to approve API access and OAuth scopes for the integration. Managed credentials should be stored securely, and you should rotate API keys or tokens periodically to maintain security.
Yes. Use the update endpoints (PUT /contacts/:contactId, PUT /contacts/:contactId/tasks/:taskId, etc.) to modify existing records. To prevent duplicates, implement idempotent logic by using stable identifiers like contactId or a unique email as the canonical key. Leverage Zapier filters and search steps to detect existing records before creating new ones.
If a request fails, review the HTTP status code and error body for specifics. Common issues include invalid tokens, missing required fields, or insufficient permissions. Implement retries with backoff in Zapier and consider implementing webhooks for real-time error notifications so you can respond quickly.
Yes. Start with a basic flow, such as creating a contact when a new lead enters your CRM, then add notes and tasks to the contact. Expand to tagging, updates, and cross-system sync as you validate mappings. Use test data to iterate safely before going live.
To revoke access, disconnect the Zapier App Connector from your GHL account and revoke the OAuth token. Rotate any API keys and update your Zapier connections to ensure no stale credentials remain. Review audit logs to confirm there are no active automations using the credentials.
Due to high volume, we will be upgrading our server soon!
