What this category’s data looks like
Financial lease yield rate data is sourced from project ledgers in internal business management systems of financial lease companies, and public industry lease asset market data platforms. Data is updated at a fixed daily time, with full existing project data for the prior natural day refreshed. Exports are available in structured JSON or CSV formats. Core fields include project number, lessee’s unified social credit code, lease principal, annualized lease yield rate, lease start date, maturity date, project status, and days past due. Lease principal is measured in ten thousand yuan, and annualized yield rate is measured in percentage.
Constraints on HTTP Interfaces and External Systems
Financial lease yield rate data comes from both internal business systems and third-party industry data platforms. HTTP interfaces must adapt to multiple authentication mechanisms, including API key signing and OAuth2 authorization. Daily fixed-time bulk update requirements mean pull tasks must be configured for scheduled triggering. Interface timeout settings must accommodate the transmission volume of thousands of project records per batch. Fields include sensitive information such as unified social credit codes, so desensitization rules must be configured during interface calls and data storage. Enumerated fields such as project status must align strictly with external system enumerated values to prevent data parsing failures.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
api_request_timeout | 600–1200 seconds | Accommodates transmission and parsing time for thousands of financial lease project records per batch |
scheduled_task_cron | 0 18 * | Matches the fixed daily 18:00 data update time |
data_desensitization_enabled | Enabled | Processes sensitive fields such as unified social credit codes to comply with data compliance requirements |
auth_type | Hybrid authentication | Supports integration with both internal business system API keys and third-party platform OAuth2 authorization |
enum_field_mapping | Calibrated via actual testing | Aligns project status enumerated values between external systems and internal business systems |
batch_fetch_size | 500 records per request | Splits bulk data to avoid overloading single interface requests |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by data format, data volume, and business rules. Specific issues require targeted analysis, and testing against local samples is recommended before finalizing settings.
Three Common Misconfigurations
- Issue: Interface returns 401 Unauthorized status code. Cause: External system authentication parameters are not configured correctly, and API keys from internal systems and third-party platforms are mixed.
- Issue: Scheduled pull tasks time out and interrupt. Cause: The
api_request_timeoutvalue is not adjusted, and the default short timeout setting is used, which cannot accommodate bulk data transmission. - Issue: Data parsing failure error is returned during debug preview. Cause:
enum_field_mappingis not configured, and enumerated values returned by external systems do not match internal parsing rules, resulting in filtered fields.
How to Confirm Proper Configuration
- Call the configured HTTP interface, verify returned fields include expected fields such as project number and annualized yield rate, and confirm units match preset rules.
- Manually trigger a scheduled pull task, confirm task logs show successful data pull and parsing, with no timeout or authentication errors.
- Verify sensitive fields such as unified social credit codes have been desensitized according to configured rules.
- Compare sample data from the external system on the current day with pulled local data, confirm enumerated field values such as project status are fully aligned.
