Salesforce enforces platform limits to maintain stability in a multitenant environment. These constraints dictate integration design by capping concurrent connections, daily API calls, and transactional resource usage.

Core information
  • API request limits fall into three categories: concurrent requests, total daily allocations, and per-transaction governor limits.
More details and nuances
  • Concurrent request limits only apply to calls exceeding 20 seconds in duration; shorter requests do not count toward the 25-call production cap.
