Obtain your GHL credentials with the Contacts API scope (contacts.readonly) and authorize Zapier to read contact data.
Link your Zapier connection to GHL using OAuth or an API key, then grant access to the Contacts endpoints.

Build powerful automations without writing code
Drag-and-drop workflow builder connects GHL data to Instagram for Business in minutes
Reliable data sync with built-in retries and error handling
Key terms cover API endpoints, OAuth, webhooks, rate limits, and data fields you’ll encounter when integrating GHL with Zapier and Instagram for Business.
A URL and HTTP method used to access a specific resource in the GHL API.
OAuth is an open standard for granting secure delegated access to user data without sharing credentials.
A webhook is a user-defined HTTP callback that triggers when a specified event occurs in your app or service.
APIs enforce limits on how many requests you can make in a given time window.
Use new contact data to automatically build Instagram audience segments for targeted campaigns.
Create follow-up tasks when notes are added to a contact to respond to comments or messages.
Keep Instagram posting aligned with contact updates by syncing fields to scheduling actions.
Log in to Zapier, choose the Zapier App Connector, and authorize access to the Contacts API.
Select a GHL trigger (e.g., new contact) and map fields to your Instagram for Business workflow.
Run tests, verify data flow, and switch on the Zap for production.
Some endpoints are read-only and require only the contacts.readonly scope. If you need write capabilities, request additional permissions or use designated write endpoints. Always test in a sandbox to confirm access. In production, monitor for failures and implement retries.
Authenticate with GHL by obtaining OAuth credentials and granting your Zapier App Connector access to the Contacts API. Securely store tokens and refresh them before expiration. Use the correct scope (contacts.readonly) for read operations unless you need write access.
Common synced fields include contactId, firstName, lastName, email, phone, and tags. Specific endpoints expose different fields; map only the required ones in your Zapier workflow to avoid extra data transfers.
Instagram posting can be driven by data in GHL via Zapier, but actual publishing depends on Instagram Graph API permissions. You can schedule reminders or create notes to coordinate posts, while respecting Instagram’s posting rules.
Check Zapier task history and GHL API logs for errors. Validate OAuth tokens, endpoint paths, and field mappings. Ensure the connection has the required permissions and that the endpoint exists.
Endpoint documentation is available in your GHL developer portal. This guide provides summarized references and examples for common tasks when pairing GHL with the Zapier App Connector.
Due to high volume, we will be upgrading our server soon!
