Frequently Asked Questions

Do I need to write code to connect Lawmatics with the GHL Contacts API?

No coding is required for many common uses. Lawmatics and the GHL Contacts API can be connected through no-code automation builders, webhooks, and standard API connectors. If you choose to code, you can customize field mappings, error handling, and batch syncing to fit complex workflows.

You can sync core contact data (name, email, phone), tasks, notes, and appointments. You can also sync custom fields like tags and businessId, enabling a complete data picture across both systems.

Authentication uses OAuth tokens or API keys issued by GHL and stored securely in Lawmatics. No-code setups typically handle token exchange via the UI, with secure storage and automatic refresh where supported.

Start with read operations such as GET /contacts/:contactId to verify access and see data structure. Then add creating and updating endpoints (POST /contacts/ and PUT /contacts/:contactId) to enable bidirectional sync, followed by related endpoints for tasks and notes.

Yes, you can set up bi-directional syncing for tasks and notes using the appropriate POST/PUT endpoints. Implement conflict resolution by preferring the latest timestamp and using id mappings to avoid duplicates.

API rate limits depend on your GHL plan and usage; monitor request count and back off when limits are approached. Design flows to batch smaller requests, retry failed calls with exponential backoff, and log errors for quick troubleshooting.

Common issues include invalid tokens, incorrect scopes, or endpoint outages. Check token validity, refresh tokens if needed, verify field mappings, and review the integration logs to identify where requests fail.
