To access the GHL Contacts API you’ll need a valid API key or OAuth token. Use the appropriate scope (for example, contacts.readonly for read-only operations) and keep credentials secure.
The Kickbox integration connects to the GHL Contacts API via API keys and OAuth tokens configured in the Zapier App Connector. Store credentials securely and rotate tokens regularly.

An overview of core concepts like endpoints, authentication, triggers, actions, and data fields that power the integration.
URLs that expose specific capabilities of the GHL API to read or modify data.
Methods to verify identity and authorize actions (API keys, OAuth tokens).
Events that start a workflow when data changes.
Operations performed by a Zap, such as GET, POST, PUT, DELETE.
Automatically enrich new leads with contact details from Kickbox and update GHL.
Create tasks when a contact’s status changes to keep your team aligned.
Sync Kickbox notes into GHL notes for a unified activity history.
Register your Kickbox app and generate an API key and OAuth token.
Configure endpoint calls in the Zapier App Connector for read and write operations.
Test the workflow and deploy to production with monitoring.
Authentication to the GHL Contacts API is provided via API keys or OAuth tokens. Ensure your credentials have the required scope (for example, contacts.readonly for read access) and never expose keys in logs. Token rotation and secure storage are essential. In automated workflows, use the Zapier App Connector’s secure vault to manage credentials and apply least-privilege access wherever possible.
The primary read endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, and GET /contacts/. You can also fetch business-scoped data with GET /contacts/business/:businessId. For write operations, you can POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, and POST /contacts/:contactId/tags to add or modify data.
Yes. You can create tasks for a contact with POST /contacts/:contactId/tasks, including details like title, due date, and status. You can update a task with PUT /contacts/:contactId/tasks/:taskId and mark completion with PUT /contacts/:contactId/tasks/:taskId/completed. Deleting a task is possible via DELETE /contacts/:contactId/tasks/:taskId.
Rate limits depend on your GHL plan and API access. If a limit is reached, implement exponential backoff in your Zapier workflow and space out requests. The Zapier App Connector can help manage retry behavior and token refreshes to stay within quotas.
Common errors include invalid or expired tokens, missing required fields, or 404 errors due to incorrect contactId. Check the API response for error codes and messages, then adjust requests accordingly and retry with backoff where appropriate.
You can filter or fetch by businessId using GET /contacts/business/:businessId to retrieve contacts for a specific business. In Zapier, map the businessId field and use separate workflows or filters to segment data by business.
Yes. The Zapier App Connector enables no-code connections with triggers and actions for the GHL Contacts API and Kickbox. If you need deeper customization, you can add lightweight webhooks or a minimal code step for advanced logic.
