Concurrency per group

  • Each sandbox group can have up to 1,000 concurrent sandboxes.
  • To resume a suspended sandbox, its group must have available capacity.
  • While a group is at its concurrency limit, requests to create or resume a sandbox fail with HTTP code 429.
    • To reclaim capacity, terminate sandboxes you no longer need.

API rate limits

Sandbox API operations have separate default rate limits. These limits apply per user, shared across that user's API keys. Requests that exceed a rate limit fail with HTTP code 429.
