How We Ensure the Security of Public APIs

safety

Public APIs foster connectivity and innovation, but openness must be backed by strong safeguards. We apply multi-layered security measures to protect your data, operations, and partnerships.

Authentication & Authorization

Role-Based Access We use OAuth 2.0 tokens to verify identities and assign precise permissions based on user roles.
Resistance to Attacks Every request is authenticated, and rate limiting prevents brute-force attacks on auth endpoints.
Encrypted Communication All endpoints require HTTPS, protecting data in transit.

API Key Management

Unique & Secure Identification API keys serve as distinct identifiers with set usage restrictions and expiration.
Lifecycle Management Automatic rotation, monitoring, and prompt revocation of unused or compromised keys keep access secure.
Best Storage Practices We encrypt keys and ensure they never enter code or logs.

Threat Mitigation

Strict Input Validation All incoming data is validated to prevent injections and other exploits.
Robust Monitoring & Error Handling Minimal error disclosure and continuous traffic monitoring help us quickly spot and block suspicious activity.
Smart Rate Limiting Adaptive limits protect each endpoint based on user level and sensitivity.
