Tokens

• Access Token Lifetime: 1 hour default (configurable 300-172,800 seconds)
• Refresh Token Lifetime: 30 days default (SCIM: up to 450 days)
• Token Storage: Vault required for production (not code/git)
• Token Rotation: March 2026 change - view-once-only secret

Rate Limiting

• Standard Limit: 60 requests/minute per application
• Backoff Strategy: 3s → 9s → 27s → 5-min increments
• Platform Volume: 8+ billion API requests/week processed
• Optimization: Bulk APIs reduce 99.99%, WebSockets reduce 99%

Scopes

• Format: resource:action (e.g., conversations:readonly)
• Enforcement: User permissions AND OAuth scope required (both)
• Best Practice: Principle of least privilege
• Usage: Space-separated list in requests

Security

• Client Secret: Store in vault (Hashicorp, AWS, Azure)
