  Rate limits for the Thoughtly public API. Limits are uniform across plans
  (per-key) and a 429 response indicates throttling.
sources:

responseCodes:
  throttled: 429
  quotaExceeded: 429
algorithm: fixed-window
limits:
  - tier: All API keys
    surface: REST API
    rpm: 100
    description: 100 requests per minute per API key across all endpoints.
retry:
  webhookDelivery: Thoughtly does NOT auto-retry failed webhook deliveries. A 429 from a subscriber URL is retried once, respecting the Retry-After header.
guidance:
  - Apply exponential backoff on 429 responses.
  - Use Automations + Audiences for high-volume outbound campaigns rather than tight per-contact loops.
