Authenticate requests to the Contacts API with your GHL credentials. This page uses the scope ‘contacts.readonly’ to allow reading contact data, ensuring you can pull information into Knack without modifying records.
Connect Knack to the GHL Contacts API using the Zapier App Connector. After linking accounts, map fields between GHL and Knack and configure triggers to keep data in sync.
Endpoints included: 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 and push that data to Knack as a new or updated record.
Actions: create or update a Knack contact; update fields such as email, name, and phone; optionally create associated notes or tasks.
GET /contacts/:contactId
id, email, firstName, lastName, phone, company
Trigger when a GHL task is created or updated for a contact.
Actions: create or update a Knack task linked to the corresponding contact; update status and due date.
GET /contacts/:contactId/tasks
taskId, title, status, dueDate, contactId
Trigger when notes are added or updated for a contact in GHL
Actions: create or update notes in Knack; attach them to the right contact
GET /contacts/:contactId/notes
id, content, createdAt, contactId
Rapid setup with the Zapier App Connector; no custom code required
Automate two-way data flow between GHL and Knack with triggers and actions
Create scalable CRM workflows and reports without writing code
Key elements and processes covered here include authentication, endpoints, triggers, actions, data mapping, and error handling that enable connecting the GHL Contacts API with Knack via the Zapier App Connector.
Application Programming Interface: a defined set of rules that allows apps to talk to each other and exchange data.
A specific URL in an API that performs an action or returns data.
The process of verifying identity to access data, typically via OAuth2 or API keys.
The data sent in requests and received in responses.
Automatically generate Knack contact records when a new contact is added in GHL, ensuring consistent data mapping.
Push notes from GHL to the corresponding Knack contact so context moves with the record.
Automatically generate follow-up tasks in Knack when related GHL events occur, keeping teams aligned.
In Zapier, connect your GHL and Knack accounts using the App Connector.
Map GHL contact fields to Knack fields (for example, email, name, and phone) to enable accurate syncing.
Set up triggers for new or updated contacts and corresponding actions; run tests and deploy.
No code is required. You can connect GHL and Knack via the Zapier App Connector and build reliable workflows in minutes. Map fields and set triggers to automate data movement. If your workflow needs more control, you can adjust filters and data mapping within the Zap.
You can sync core contact fields such as id, name, email, and phone, plus related data like tasks and notes. The example endpoints support read operations; you can extend this with writes if your access scope allows.
Data is transmitted over secure channels and authenticated via your GHL and Knack accounts. Use standard security practices and review any compliance requirements for your organization.
Yes. You can push and pull notes and tasks between GHL and Knack. You can design triggers to keep notes attached to the correct contact and tasks linked to the proper record.
Yes. You can apply filters in Zapier to control which contacts are synced. For example, sync only active contacts or those with a specific tag or field value.
When conflicts occur (data edits in both systems), the Zap can be configured to prioritize one source or to log conflicts for review. You can implement versioning in Knack to track changes.
If you encounter errors, check the connection status, review field mappings, and test each step of the Zap. Use the Zapier task history and API endpoint logs to diagnose issues and adjust configurations.
Due to high volume, we will be upgrading our server soon!
