Authenticate requests to the Contacts API using your GHL API key or OAuth credentials. Ensure the requested scopes include at least contacts.readonly (and write access if you need to create or update data). Guard credentials securely and rotate keys as recommended.
In Zapier, connect by selecting your GHL account and granting the necessary permissions. Use the provided OAuth flow or API key method as supported by the connector, with the appropriate scopes (e.g., contacts.readonly to start, enabling write as needed).
Key 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 contact is created or updated in GHL, then sync related data to Zapier workflows.
Actions: create or update related tasks, notes, and tags via the Contacts API (POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes, POST /contacts/:contactId/tags).
Methods/paths used: GET /contacts/:contactId to fetch; POST /contacts/ to create; PUT /contacts/:contactId to update.
Key fields: contactId, name, email, phone, tags.
Trigger when notes or tasks are added or updated for a contact in GHL.
Actions: create notes via POST /contacts/:contactId/notes and create tasks via POST /contacts/:contactId/tasks.
Paths: POST /contacts/:contactId/notes; POST /contacts/:contactId/tasks; GET /contacts/:contactId/notes; GET /contacts/:contactId/tasks.
Fields: contactId, noteId, taskId, title, description.
Trigger: when tags are added or removed on a contact.
Actions: manage tags via POST /contacts/:contactId/tags; retrieve and update business data with GET /contacts/business/:businessId and PUT as needed.
Paths: POST /contacts/:contactId/tags; GET /contacts/business/:businessId.
Fields: contactId, businessId, tags.
Automate repetitive contact workflows without writing code.
Orchestrate data flows between GHL and your apps using visual workflows in Zapier.
Accelerate onboarding and reduce manual data entry.
This glossary defines API, endpoints, authentication, webhooks, data fields, and typical processes used to connect the GHL Contacts API with Zapier App Connector.
Application Programming Interface that exposes data and actions in a programmable way for the GHL platform.
An industry-standard authorization protocol used to grant scoped access without sharing user credentials.
Real-time notifications sent from GHL to Zapier when data changes.
A specific URL path in an API that performs an action or returns data.
Use QRTIGER QR codes to capture contact data and push it into GHL via the Contacts API when scanned; trigger a Zap to create or update the contact record automatically.
Predefine task templates that populate in GHL when a QR is scanned and linked to a contact.
Append notes and observations captured via QR codes to the related contact in GHL.
Provide your GHL credentials and authorize the Zapier App Connector to access Contacts data.
Choose and map endpoints like GET /contacts/:contactId and POST /contacts/ to your Zapier workflows.
Create triggers and actions using the available endpoints to automate contact data flows.
GHL provides a RESTful API that exposes contacts, notes, tasks, and more. The Zapier App Connector acts as a bridge to trigger workflows and perform actions using those endpoints. You’ll authenticate with an API key or OAuth and map fields between GHL and the apps you connect. This setup enables no-code automation across your CRM data.
The Contacts API includes endpoints for retrieving and updating contacts, tasks, notes, appointments, and tags. Common endpoints we reference are GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes, and POST /contacts/:contactId/tags. You can mix and match to fit your workflow needs.
No traditional coding is required when using the Zapier App Connector. You’ll configure triggers and actions in a visual editor and map API endpoints to fields. Some advanced scenarios may benefit from custom code steps, but for most use cases you can build fully functional automations without writing code.
Secure authentication is achieved via OAuth or API keys. Never embed credentials in client-side code. Store secrets securely in Zapier’s vault or your preferred secret manager, rotate keys periodically, and limit scopes to the minimum necessary for the workflow.
You can sync core contact fields (name, email, phone), as well as related data like notes, tasks, and tags. Endpoints also expose business identifiers and custom fields depending on your GHL setup. Always map fields carefully to maintain data integrity across systems.
Rate limits vary by endpoint and authentication method. Best practices include batching operations where possible, retrying with exponential backoff, and queuing large sync tasks. If you hit limits, optimize workflow steps to avoid excessive calls per trigger.
If syncing issues arise, check authentication status, confirm endpoint availability, review mapped fields for mismatches, and inspect Zapier task history for errors. Logs often indicate which endpoint failed and why, guiding quick fixes.
Due to high volume, we will be upgrading our server soon!
