Reach out with details about your use case:
Concurrency per group
- Each sandbox group can have up to 1,000 concurrent sandboxes.
- Suspended sandboxes do not count toward this limit.
- You can reduce the concurrency limit for an individual group.
- 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.
