Frequently Asked Questions

What is the GHL Contacts API?

The GHL Contacts API provides a programmatic way to access and manage contact data, including tasks, notes, and appointments. It enables you to read and interact with contact records from external apps without using the official UI. This makes it ideal for building no-code or low-code automations with Stackby.

Endpoints cover common operations like retrieving individual contacts, their tasks, notes, and appointments, as well as creating and updating these items. Use these endpoints to assemble the data you need in Stackby and to push updates back when appropriate. Not all endpoints are required for every page—pick the ones that fit your workflow.

No coding is required to connect Stackby to the GHL Contacts API. Use Stackby’s connectors and field-mapping capabilities to set up data flows, triggers, and actions between Stackby and GHL. This guide is designed for no-code users and lightweight developers alike.

Authenticate using a API key or OAuth token issued by your GHL account. Keep credentials secure, rotate keys periodically, and grant only the minimum required scope (e.g., contacts.readonly) if you do not need write access. Use securely stored credentials in Stackby’s connection settings.

Yes. Field mappings let you specify exactly which GHL data fields map to which Stackby columns. You can rename fields for clarity, transform values, and handle optional fields to ensure data integrity across systems.

You can sync core contact data, related tasks, notes, and appointments. The integration supports creating, updating, and linking records across both platforms, so you can build a unified view of each contact.

Rate limits depend on your GHL plan. Plan for typical request bursts and implement simple retries with backoff in Stackby to avoid hitting limits. If you anticipate high traffic, consider staggering synchronization schedules.
