Technical Limitations

API Call Limits (Service Protection) Limited to 60,000 API requests per user per 5-minute period (standard tier); exceeding this causes throttling. Storage Limits Each environment has database, file, and log storage limits based on licensing. Extra storage comes at a cost. Custom Entities and Fields Max 3,000 custom entities per environment Max 1,000 fields per entity (including out-of-box fields) Workflow and Flow Timeout Power Automate flows and classic workflows can time out or fail if they run too long or hit resource constraints. Plugin Execution Timeout Server-side plugins must complete execution within 2 minutes (sandboxed), else they are terminated.API Call Limits (Service Protection)
