Frequently Asked Questions

Do I need coding knowledge to set this up?

No deep coding knowledge is required. The integration is designed for teams using no-code tools to connect systems. You can configure endpoints, mapping, and triggers from the APPNAME dashboard. Two: Start with a sandbox or test environment, then progressively enable live data sync. Use the provided examples to validate that data flows correctly between the GHL Contacts API and FastField Mobile Forms.

You can read contact details, tasks, notes, and appointments. Write operations include creating or updating contacts and tasks, subject to your security and permission settings. Since the scope shown is readonly in this scenario, actual write permissions may require additional configuration. If you need write access, update the integration scope or use separate API credentials with write permissions from GHL.

Yes, you can create tasks in GHL from FastField Mobile Forms by mapping to POST /contacts/:contactId/tasks. Two: Ensure required fields like title and dueDate are provided and that the target contact exists before creating the task.

Security is ensured via OAuth 2.0 or API keys, with tokens restricted by scope. Keep credentials secure, rotate them periodically, and limit access to only what is necessary. Consider enabling IP allowlists and monitoring access logs to detect unusual activity.

Rate limits depend on your GHL plan and the API tier you use. In general, plan for moderate traffic and avoid burst-heavy requests. If you approach limits, implement exponential backoff, stagger your syncs, and cache data where appropriate.

Yes. Data mappings can be customized per contact type or business to suit different workflows. Use APPNAME data maps to align fields across systems. Test each mapping for accuracy and adjust as your data model evolves.

Use the built-in test endpoints and a sandbox environment to validate the flow before going live. Enable detailed logging and set up dashboards to monitor data integrity and sync status over time.
