Authenticate to the Contacts API using OAuth 2.0. Obtain an access token via your GHL developer setup and include it in the Authorization header for each request. Scope: contacts.readonly governs what you can read.
In Zapier, establish an OAuth 2.0 connection to the Contacts API. Zapier will handle token refreshes and securely store credentials so your Zaps can run without manual sign-ins.
GET /contacts/:contactId — Retrieve a single contact by ID; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/notes — List notes for a contact; POST /contacts/ — Create a contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; GET /contacts/ — List all contacts; GET /contacts/business/:businessId — List contacts for a business; GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task; GET /contacts/:contactId/appointments — List appointments for a contact; POST /contacts/:contactId/tasks — Create a 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: A new contact is created or an existing contact is updated in GHL, starting a Zap in Zapier to sync data with other apps.
Actions: Create or update a contact in GHL; optionally create related tasks or attach notes and tags.
POST /contacts/ (create) or PUT /contacts/:contactId (update).
Key fields: name, email, phone, company.
Trigger: A new task is created for a contact in GHL to start downstream automations in Zapier.
Actions: Create or update tasks for a contact; update task status; set due dates.
POST /contacts/:contactId/tasks or PUT /contacts/:contactId/tasks/:taskId
Key fields: contactId, title, dueDate, status.
Trigger: A new note is added or a tag is applied in GHL to trigger an automation in Zapier.
Actions: Create notes on a contact; add tags to a contact; optionally attach files.
POST /contacts/:contactId/notes and POST /contacts/:contactId/tags
Key fields: contactId, note content, tag name.
No-code integrations let you automate repetitive CRM tasks fast without writing a line of code.
Drag-and-drop workflow creation in Zapier makes it easy to assemble triggers, actions, and data mappings.
Scalable automations run 24/7, syncing contacts, tasks, notes, and more across tools.
Key elements include authentication, endpoints, triggers, actions, and data mapping to move information between GHL and Zapier.
A real-time notification mechanism used by GHL and Zapier to push data without polling.
An authorization framework that lets apps access API data securely on behalf of a user.
A specific URL path in an API that performs a defined action (read, write, delete).
A credential string used to authorize API requests and is typically short-lived with refresh tokens.
Capture form submissions, create a contact in GHL, assign a welcome task, and trigger a personalized email sequence—all via Zapier.
Keep contacts in sync across GHL and your email or marketing apps with real-time webhooks and Zapier tasks.
A daily summary of contact activity (tasks, notes, and appointments) compiled in Zapier and delivered to your team.
Create a new connection in Zapier and authorize access to your GHL Contacts API.
Select a trigger (e.g., New Contact) and map fields to your actions (create/update, notes, tags).
Run tests, review results, and turn on the Zap for ongoing automation.
Mapping fields between GHL and Zapier is straightforward with data mapping in Zapier. Start by selecting the source field (e.g., contact name, email) and map it to the destination field you want in Zapier actions. Use consistent field names to minimize mapping errors and improve data quality. If a field is missing, you can create a custom mapping or use a formatter step to transform data before it’s sent to the endpoint.
Yes. The Contacts API supports reading and writing data when using the correct scope and permissions (e.g., contacts.readonly or full read/write). Ensure your access token has the necessary scope for the operations you perform, such as GET, POST, PUT, and DELETE. Always validate permissions in a test Zap before going live.
Key endpoints for managing tasks include GET /contacts/:contactId/tasks (list tasks for a contact), POST /contacts/:contactId/tasks (create a task), PUT /contacts/:contactId/tasks/:taskId (update a task), PUT /contacts/:contactId/tasks/:taskId/completed (mark complete), and DELETE /contacts/:contactId/tasks/:taskId (delete a task). You can chain these with triggers to automate task workflows.
Secure authentication is essential. Use OAuth 2.0 to obtain access tokens and refresh tokens, store tokens securely, and rotate credentials regularly. In Zapier, rely on the built-in OAuth flow and encrypted storage to keep credentials safe. Never share tokens in logs or public channels.
Latency is typically low, often measured in seconds, but it can vary based on app performance and network conditions. For critical automations, design Zaps to handle retries and use idempotent operations to avoid duplicate actions in GHL.
Yes, rate limits apply. If you hit limits, implement exponential backoff and retries in Zapier, and consider batching or staggering requests. You can monitor quota usage in your API dashboard and adjust Zap schedules accordingly.
When a Zap fails, check the error message for the failing endpoint and payload. Verify authentication, data mappings, and required fields. Retry with idempotent actions where possible, and use test data to reproduce the issue before re-running in production.
Due to high volume, we will be upgrading our server soon!
