Use your GHL API credentials to grant the Zapier App Connector access to the Contacts scope (contacts.readonly by default).
During setup, authorize the Zapier App Connector to access your GHL data via OAuth 2.0 or the chosen method, so workflows can read contacts and push updates.
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 updated or a new task is created in GHL, firing an update in your Zapier workflow.
Actions: create or update contact records, attach notes, and assign tasks to reflect LinkedIn activity in your CRM.
Method examples: GET /contacts/:contactId to fetch details and POST /contacts/ to add a new contact.
Key fields: contactId, email, name, phone, linkedinProfile, campaignSource.
Trigger: on-demand fetch to pull contact insights for reporting on conversions.
Actions: list tasks and notes for a given contact to enrich LinkedIn data.
GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes
Key fields: contactId, taskId, noteId.
Trigger: new contact created triggers downstream workflows.
Actions: create and update contacts, tag management, and task creation.
POST /contacts/ to create, PUT /contacts/:contactId to update
Key fields: email, firstName, lastName, phone, businessId.
Build powerful automations without writing code, saving time and reducing manual data entry.
Keep contact data synchronized across tools (GHL, LinkedIn, CRM) for accurate reporting.
Scale campaigns with reusable workflows that trigger on conversions, updates, and tasks.
This section covers core elements and processes: endpoints, authentication, data mapping, triggers, actions, rate limits, error handling, and testing.
GHL refers to the platform API and CRM ecosystem used to manage contacts, tasks, notes, and appointments.
An API path that performs a specific operation on a resource, such as retrieving a contact or updating a task.
OAuth 2.0 is the authorization framework that lets the Zapier App Connector access GHL data securely without sharing credentials.
API rate limits define how many requests you can make in a given window; plan your automation accordingly.
Automatically pull contact data from GHL when a new LinkedIn lead is captured and update your CRM.
Create tasks in GHL when LinkedIn conversions require follow-up, with reminders in LinkedIn messaging.
Consolidate notes from LinkedIn interactions into GHL notes for each contact.
Ensure you have a valid API key or OAuth credentials and confirm the contacts.readonly scope is granted.
Use the Zapier App Connector setup flow to authorize access and run a test to fetch a sample contact, tasks, and notes.
Create a Zap that triggers on a LinkedIn conversion and maps fields into GHL Contacts, then add actions to update tasks or notes.
You’ll typically start by choosing the read-only scope for initial testing, using GET endpoints like /contacts/:contactId to fetch data and verify mapping. As you expand, you can enable write permissions to create or update contacts. Use sandbox data to validate field mappings and ensure LinkedIn data aligns with your GHL contacts. The goal is a safe, reversible test environment before going live.
No traditional coding is required. The Zapier App Connector provides a visual workflow builder that maps LinkedIn conversion data to GHL Contacts using predefined actions. Start with read-only access to explore data flow, then gradually enable write actions as you confirm accuracy. This keeps setup fast and safe for non-developers.
Authentication is done via OAuth 2.0 (or your chosen method) to authorize the Zapier App Connector to access GHL data. You’ll authenticate in the GHL account, grant the requested scopes (starting with contacts.readonly), and then test by pulling sample data. Repeat the flow to refresh tokens as needed and ensure a stable connection.
Map essential fields such as contactId, email, firstName, lastName, phone, and any business identifiers from LinkedIn to the corresponding GHL contact fields. Consider mapping LinkedIn identifiers for deduplication and linking LinkedIn campaigns to contact records for richer analytics. Always validate mappings with sample records before going live.
Yes. The GHL API enforces rate limits based on your plan and endpoint usage. When building automations, batch requests where possible and implement retry logic for 429 responses. Monitoring tools in Zapier will help you identify throttling and adjust trigger frequencies accordingly.
Yes. You can update existing contacts via PUT /contacts/:contactId and modify related tasks or notes. Ensure you have write permissions enabled in your OAuth scope. Test updates in a sandbox environment to confirm data integrity and avoid unintended overwrites.
Start with a dry run in Zapier using a sample LinkedIn conversion and a test contact. Verify field mappings, triggers, and actions in the workflow editor, then run a live test with a small dataset. Review logs and inspect the updated GHL contact to confirm the integration behaves as expected before full deployment.
Due to high volume, we will be upgrading our server soon!
