How to connect inFlow Inventory to Contacts API with GHL

Seamless two-way data syncing between GHL Contacts API and inFlow Inventory

Steps to connect GHL Contacts API with inFlow Inventory

This guide shows how to link the GHL Contacts API (readonly scope) with inFlow Inventory to enable streamlined contact management, tasks, notes, and more. Learn authentication, available endpoints, and example flows that keep data in sync without writing code.

Authenticate the GHL Contacts API

Obtain GHL API credentials and grant your inFlow Inventory app the contacts.readonly scope. Use OAuth 2.0 or API keys as supported by the GHL platform, then configure the connection in your Zapier App Connector.

Frequently Asked Questions

What data can I access with the GHL Contacts API?

The GHL Contacts API exposes endpoints to read contact info, notes, tasks, and more. With the readonly scope, you can pull contact records into inFlow Inventory and keep timelines up to date. If you need write access, upgrade the scope accordingly. For best results, set up a dedicated integration user and test in a staging environment before going live.

No heavy coding is required. Use the Zapier App Connector to map fields between GHL and inFlow and configure triggers and actions. If you need more complex logic, simple scripts or conditional steps can be added inside your workflow. Start with a basic read-only flow and iterate as you gain confidence.

The typical required scope is contacts.readonly to start, with potential upgrades to write access for full bi-directional flows. Authentication is handled via API keys or OAuth depending on your setup. Always restrict credentials to the minimum necessary permissions and rotate keys regularly.

Yes. When configured correctly, changes in GHL can be mirrored in inFlow and vice versa, using triggers and corresponding actions. Test carefully to ensure data is not overwritten unintentionally. Consider adding a review step for critical data before enabling full bidirectional syncing.

Respect API rate limits by pacing requests and using batching where possible. Implement retry logic with exponential backoff and log errors for troubleshooting. Monitor quota usage in both platforms to prevent interruptions. Enable alerting for failures to keep the integration healthy.

Essentials include reading contacts (GET /contacts/:contactId), listing a contact’s tasks (GET /contacts/:contactId/tasks), and creating/updating tasks (POST /contacts/:contactId/tasks). These endpoints enable a solid core flow for contact management and task tracking. Add notes (GET /contacts/:contactId/notes) and a basic contact creation path (POST /contacts/) as needed.

Refer to the integration docs and example flows in the Zapier App Connector. Look for step-by-step walk-throughs, field mappings, and sample payloads. Community forums and product support can provide additional templates. You can also request tailored examples for your exact data model and business rules.
