  - Rate Limiting
description: >-
  LambdaTest REST APIs are rate-limited per user account. The platform enforces
  concurrency limits based on the purchased parallel session tier rather than
  publishing fixed request-per-minute caps in public documentation. The API
  returns HTTP 429 when throttled. Concurrency limits (parallel sessions) are
  plan-based: Free includes 2 sessions, and paid automation plans add sessions
  per purchased license. The manual-api and mobile-api endpoints enforce
  additional upload-size and frequency limits specific to app testing workflows.
