API: Authentication
Overview
Syllecta public APIs use bearer tokens (API keys). Every request must include:
Authorization: Bearer <api_key>
API keys map to a tenant, plan, and usage limits in Backoffice.
Base URLs
- Cloud: use the base URL provided in your workspace (e.g.,
https://cloud.syllecta.example). - Local:
http://localhost:4000(cloud-api dev server).
