Frequently Asked Questions

What data can I access with the Contacts API scope?

With the Contacts API readonly scope you can view contacts, their tasks, notes, and appointments. Write access is not granted by default. If you need additional permissions, adjust the scope accordingly. Always follow best practices for securing credentials.

No-code options via Zapier or pre-built templates exist to simplify setup. Some mappings and field choices may require a light touch of configuration, but you can complete most setups without writing code.

Real-time syncing depends on webhook support and your chosen automation platform. Zapier can poll for changes or use webhooks, delivering near real-time updates in many cases.

Both GHL and Zapier impose rate limits. Plan for retries and batch operations where possible, and monitor usage in the dashboards.

Implement idempotent actions and conflict resolution rules to avoid duplicate records and ensure consistent data across apps.

Yes. Zap templates and quick-start guides are available to accelerate setup; customize fields to fit your workflow.

Use OAuth for secure authorization, keep credentials private, rotate keys regularly, and review permissions periodically.
