Rate Limiting

Rate Limiting

VoP implements configurable rate limiting to ensure stable and efficient processing of payment verification requests while maintaining SEPA compliance and system performance.

Rate Limit Configuration

Rate limits are fully configurable during system setup and can be adjusted based on:

• Transaction volume requirements
• Available infrastructure capacity
• SEPA processing requirements
• Expected peak processing times
• Bank-specific compliance requirements
• Business continuity needs

Note

Rate limits should be carefully planned during the initial system setup phase. Contact your VoP implementation team to discuss your specific requirements.

Rate Limit Headers

Each API response includes monitoring headers to help track usage:

X-RateLimit-Limit: {configured-limit}
X-RateLimit-Remaining: {remaining-requests}
X-RateLimit-Reset: {reset-timestamp}
X-RateLimit-Type: {limit-type}

Processing Time Guidelines

Operation Type	Target Response Time	Maximum Response Time
Single Verification	500ms	2000ms
Batch Status Check	1000ms	5000ms
Batch Submission	2000ms	10000ms

High Availability Configuration

Load Distribution

• Geographic redundancy options
• Configurable load balancing
• Automatic failover settings
• Request queue management

Peak Processing Management

• Dynamic capacity adjustment
• Priority queue configuration
• Latency monitoring thresholds
• Alert level customization

System Monitoring

Key Metrics

1. Request rate per endpoint
2. Response times
3. Queue depth
4. Error rates
5. System resource usage

Configurable Alert Thresholds

Configure alerts based on your operational requirements:

• Rate limit utilization percentage
• Response time thresholds
• Error rate thresholds
• Queue depth limits

Business Continuity

Failover Configuration

1. System health monitoring parameters
2. Performance degradation thresholds
3. Backup system activation rules
4. Operational logging requirements

Disaster Recovery Setup

• DR environment configuration
• Failover testing schedule
• Recovery procedure documentation
• Capacity planning guidelines

Compliance Requirements

Audit Trail Configuration

• Rate limit event logging
• System change tracking
• Performance metric collection
• Security event monitoring

Reporting Configuration

• Usage report scheduling
• Compliance review frequency
• Capacity assessment periods
• Audit support requirements

Technical Support Process

For rate limit adjustments:

1. Document capacity requirements
2. Prepare transaction projections
3. Complete impact analysis
4. Schedule configuration changes

Best Practices

Request Optimization

• Implement batch processing for bulk operations
• Configure client-side rate limiting
• Set up result caching where applicable
• Monitor usage patterns

Error Handling Strategy

• Configure appropriate retry intervals
• Implement backoff strategies
• Set up error logging
• Monitor failure patterns

Performance Monitoring

• Track rate limit utilization
• Monitor response times
• Analyze error patterns
• Schedule regular capacity reviews

Support Contacts

For urgent rate limit issues:

1. Follow your bank’s escalation procedures
2. Contact VoP technical support
3. Provide monitoring data
4. Schedule configuration review

Tip

Regular review of your rate limit configuration helps ensure optimal performance and compliance with SEPA requirements. Our VoP implementation team can assist with configuration adjustments as your needs evolve.
