Frequently Asked Questions

What data can I access with the Contacts API?

The Contacts API lets you read and write contact records, tasks, notes, and appointments. You can pull lists or single items and push updates to keep records in sync. Use tags to organize contacts and filter by business or status. Adopt a consistent field mapping to simplify automation. The API supports bulk and per-item operations for flexible workflows. Two-way sync ensures that updates in Transistor-fm reflect in GHL and vice versa, reducing manual data entry.

Authenticate via Transistor-fm’s built-in OAuth flow that connects to GHL. This ensures secure access and allows you to scope permissions to read or write. After granting access, Transistor-fm can perform API calls on your behalf.

Endpoints include GET /contacts/:contactId, GET /contacts/, POST /contacts/, and more for tasks, notes, and appointments. You can fetch data in bulk or per item and perform updates.

Yes. You can create notes and appointments using POST requests and update existing records with PUT requests. This supports full lifecycle management from a single app.

GHL enforces rate limits per app. If you hit limits, implement exponential backoff, batch requests, and consider using Webhooks for near-real-time updates.

No coding is required for basic integrations. The platform provides a visual mapping and triggers to automate workflows, while developers can extend with custom scripts if needed.

Use a sandbox or test environment, make sample requests, and verify responses. Validate authentication and field mappings before going live.
