Rate limiting, IP white-list

Rate Limiting и IP White-List

Robust API integration is not possible without overload and external threat protection mechanisms. To do this, we implement support for rate limiting and IP filtering, which allow you to control the frequency of API calls, restrict access to interfaces only to trusted addresses and exclude unauthorized connections.

This is critical when working with payment gateways, game cores, admin panels and public APIs.

What protection includes

Mechanism	Description and Application
Rate Limiting	Limit the number of requests per specified interval (for example, 100/min)
Per-user limit	Token or user limit
Per-endpoint limit	API Critical Method Load Control
IP White-List	API access is only allowed from specific IPs or subnets
IP Blacklist (optional)	Blocking unwanted addresses on suspicious activity

Implementation features

Support for sliding window or fixed intervals
Ability to set limits for different roles and clients
Separate policies for internal and public APIs
Logging of all excesses and access attempts from prohibited IP
Responses with HTTP codes 429 and explanation of the blocking reason

API and Platform Benefits

Protection against DDoS and automated scanners
Reduced server load and stability during peaks
Increase security by limiting access
Flexible customization by client, role, and entry point
Transparent system for managing limits and IP lists through the admin panel

Where especially relevant

Financial and Payment APIs
Elevated Administrative Interfaces and APIs
Public APIs with many external clients
Internal microservices requiring isolation and traffic control

Rate limiting and IP white-list are fundamental API security mechanisms. They allow you to maintain stability, eliminate abuse and accurately control who and how interacts with your system.
