How does financial API current limiting protection ensure the stability of financial transactions?

Financial API rate limiting protection ensures the stability of financial transactions by controlling the number of requests a user or system can make within a specific time frame. This prevents overload, abuse, or malicious attacks that could disrupt services or compromise data integrity.

How it works:

1. Prevents Overload: By setting thresholds (e.g., 100 requests per minute), rate limiting ensures the API server isn’t overwhelmed, maintaining response times for legitimate users.
2. Mitigates Abuse: It blocks excessive requests from bots or attackers attempting to exploit vulnerabilities, such as brute-force attacks on payment systems.
3. Ensures Fair Access: Prioritizes high-priority transactions (e.g., real-time payments) over non-critical requests, safeguarding critical financial operations.

Example:
A banking API might limit withdrawals to 5 requests per user per hour. If a fraudster tries to initiate 100 withdrawals, the rate limiter blocks excess attempts, preventing fund drainage.

Recommended Solution:
Tencent Cloud’s API Gateway provides built-in rate limiting, throttling, and quota management tailored for financial services. It integrates with security features like WAF and DDoS protection to ensure compliance with industry standards like PCI-DSS.
