The Contacts API offers 17 endpoints including retrieving contacts, tasks, notes, and appointments. You can tailor requests to specific contactId or businessId as needed. Our guide lists endpoints 1-17 to cover common workflows.
No code is required. The Zapier App Connector handles authentication and data routing. You can configure triggers, actions, and mappings in a visual editor. If your use case grows, you can add custom fields and additional endpoints.
Use field mapping in the app to align Letterly fields to GHL fields. You can map email, name, and custom fields. If you need complex transformations, use Zapier’s built in formatter.
We respect data privacy. Scopes determine access level. Use readonly scope for data viewing. For updates, request write access.
Use test mode in Zapier to simulate data flow. Validate responses, check logs, and verify that contacts, tasks, and notes sync as intended.
API rate limits depend on your GHL plan. In most cases you can operate within typical small to medium workflows. For high-volume, consider batching requests.
Yes. The Connector supports additional apps. You can connect to CRM, email, and task apps alongside GHL.
Due to high volume, we will be upgrading our server soon!
