What This Category of Data Looks Like
Transaction rule data primarily originates from core transaction systems, compliance management document repositories, and business rule configuration centers of licensed financial institutions. Data updates do not follow a fixed schedule, and are only triggered when regulatory policies are adjusted or business processes are optimized. A single rule document typically includes fields such as applicable customer groups, effective and expiration times, trigger conditions, operation guidelines, exception scenarios, and official consultation references. Core fields include the unique rule identifier, trigger threshold (unit: yuan, times/day, etc.), and compliance basis number. Some rules include explanatory text in multiple language versions.
Constraints Imposed on HTTP Interfaces and External Systems
Since transaction rule updates have no fixed schedule and rely on real-time compliance, HTTP interfaces must support multi-dimensional queries by rule ID, effective time range, applicable customer groups, and other criteria. This prevents inconsistent rule versions caused by cache expiration. Since a single rule includes trigger thresholds with multiple types of units, interface return fields must strictly map to preset standardized fields to avoid unit confusion. The compliance basis number associated with each rule must also be returned with the interface to support traceability display during customer service. When connecting external systems, pagination parameters for returning multiple rules in a single request must be supported, to adapt to knowledge base batch synchronization requirements.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
external_api_timeout | 30 seconds | Transaction rule external interface responses typically take no more than 20 seconds, with a 10-second buffer reserved |
rule_cache_ttl | 4 hours | Transaction rule updates do not follow a fixed schedule, so the cache duration covers most business adjustment intervals |
api_filter_params | ["rule_id", "effective_time"] | Transaction rule queries require precise matching of query conditions by unique identifier and effective time |
response_field_mapping | {"trigger_threshold":"threshold","compliance_code":"basis_id"} | Map external interface fields to FastGPT's internal standardized fields to avoid field name conflicts |
batch_sync_max_size | 50 items/request | The number of rules synchronized in a single batch should not be too large, to avoid interface timeouts |
error_retry_times | 2 retries | Occasional network fluctuations do not affect rule queries, and retries can reduce failure rates |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Symptom: An empty rule list is returned after calling the external interface, or no transaction rule content appears after knowledge base synchronization. Cause: The effective time filter condition for
api_filter_paramsis not configured, resulting in the pulling of rules that have not yet taken effect or have expired. - Symptom: Interface calls hang for 10 seconds before returning a timeout error. Cause: The
external_api_timeoutconfiguration is shorter than the actual interface response duration, and the retry mechanism is not enabled, causing occasional network delays to trigger timeouts. - Symptom: The rule units displayed during customer consultations do not match the official documents. Cause:
response_field_mappingis not configured, and non-standardized fields from the external interface are used directly, leading to incorrect threshold unit parsing.
How to Verify Proper Configuration
- Call the configured external interface and verify whether the returned fields match the preset mapping relationship.
- Manually trigger a knowledge base synchronization task, and check whether the number of pulled rules recorded in the synchronization log matches the total number returned by the external interface.
- Send a simulated customer consultation request, and confirm that the returned transaction rule content includes core fields such as effective time and trigger conditions.
- Simulate a short network delay, and check whether the interface call performs retries as configured, without directly returning a timeout error.
