Limitations

Key limitations: User analytics and recordings may contain PII; use privacy controls and scoped keys. Issue resolution, alert muting, analytics interpretation, PII in logs, sampling, and retention settings can hide incidents or expose user data if automated too broadly. API automation needs client-side throttling, idempotency where supported, pagination limits, retries, and audit logging. Store credentials outside source control and use least-privilege scopes, short-lived tokens, or restricted keys where the product supports them.
