Access to the Contacts API requires appropriate credentials and a valid scope (contacts.readonly). Use OAuth 2.0 where available, or an API key for server-to-server connections, and grant the Zapier Interfaces app the necessary permissions.
Authenticate the Zapier Interfaces app with your GHL account using the OAuth flow or API key, then authorize the requested scopes to enable triggers and actions.
The Contacts API exposes read and write operations for contacts, tasks, notes, and appointments. Below are representative endpoint groups you may use in automation: 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; contacts.write; 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 the Contacts API via Zapier Interfaces.
Actions: create or update a contact, attach notes, or add tags.
Typical method paths: POST /contacts/ to create, PUT /contacts/:contactId to update.
Key fields: contactId, name, email, phone, tags.
Trigger when a contact’s tasks or notes change.
Actions: fetch tasks, fetch notes, update tasks, create notes.
Paths: GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes.
Key fields: contactId, taskId, noteId.
Trigger when a contact is created, updated, or deleted.
Actions: create, update, delete, tag, and manage tasks/notes.
Paths: POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId
Key fields: contactId, email, name, phone, tags.
Automate repetitive contact management tasks without coding.
Keep data in sync across apps in real-time.
Prototype and iterate workflows quickly with drag-and-drop automation.
Key elements include API Endpoints, Triggers, Actions, Authentication, and Data Mapping. Understanding these terms helps you build reliable automations between the Contacts API and Zapier Interfaces.
A specific URL pattern and HTTP method used to access a resource in the GHL API (for example, GET /contacts/:contactId).
The process of proving identity to authorize API requests, typically via OAuth 2.0 or API keys.
An event in GHL that starts an automation in Zapier, such as a new contact or updated record.
An operation performed by Zapier in response to a Trigger, like creating or updating a contact.
Create a seamless onboarding flow: when a new lead is added in your CRM, automatically create a Contact in the Contacts API via Zapier Interfaces and kick off a welcome task sequence.
Use triggers on task changes to keep your team aligned, automatically updating task status in the Contacts API and notifying stakeholders.
Tag contacts based on behavior, score, or lifecycle stage and route them to tailored campaigns in your marketing stack.
Connect your GHL account to Zapier Interfaces using OAuth 2.0 or API key and grant required scopes (contacts.readonly).
Choose the triggers you need (e.g., contact created) and map fields to actions (e.g., create contact, add note).
Run tests, review data mappings, and enable the Zap to run automatically.
OAuth 2.0 or API key authentication is supported. When using OAuth, authorize the Zapier Interfaces app to access your Contacts API with the required scopes. If you use API keys, securely store them and attach to requests as headers. Ensure scopes include at least read permissions for retrieval of contacts, tasks, and notes. Tip: Keep credentials secure and rotate them regularly to maintain security.
A wide set of endpoints is available, including read endpoints for contacts, tasks, notes, and appointments, and write endpoints for creating, updating, and deleting records. You can mix and match endpoints to build complex automations. Always check your current plan and permissions to confirm available endpoints. Note: Some endpoints require a business context (businessId) and proper scoping.
No heavy coding is required. Zapier Interfaces is designed for no-code automation. You connect your GHL account, map fields, and configure triggers and actions through a visual editor. Some advanced scenarios may benefit from simple scripting, but it is not required. If you need advanced transformations, use Zapier’s built-in steps to format data.
Yes. You can create, update, or delete contacts via designated endpoints. For safety, set up a test workflow and use a sandbox or test data when experimenting. Always handle destructive actions with confirmation steps.
Response times depend on your API plan and rate limits. In practice, changes can propagate in seconds to a few minutes. Use polling or webhooks where supported to reduce latency.
Common issues include missing scopes, invalid credentials, or mis-mapped fields. Verify the connected account, reauthorize when needed, and double-check endpoint paths and parameter names. Consult logs in Zapier and the GHL API to pinpoint failures.
