What the Data for This Category Looks Like
Data sources for general other intelligent due diligence reports include enterprise industrial and commercial public disclosure systems, third-party credit databases, custom-uploaded due diligence attachments, and industry research materials. Updates are triggered on demand or synchronized weekly, with no fixed real-time cycle. The document structure has no unified template. It includes custom fields such as basic due diligence object information, risk warning items, related transaction details, and industry analysis snippets. Field units include ten thousand yuan, individual units, percentage, etc. Some fields require format adaptation for different data sources.
What Constraints These Characteristics Impose on HTTP Interfaces and External Systems
Because data sources are diverse and field customization is highly flexible, HTTP interfaces must support dynamic field mapping configuration to adapt to return formats of different data sources. Because document length and data volume have wide fluctuations, request body size limits must be relaxed to avoid errors caused by exceeding file or data volume thresholds. Because update cycles are not real-time, interface polling intervals must be adapted to on-demand pulling scenarios, and overly short polling cycles should be avoided. Because field units vary, interfaces must support unit conversion parameters to ensure unified data formats when passing data to downstream systems.
How to Configure the Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | General other due diligence reports often include multiple attachments, requiring a larger single-file upload limit to accommodate this use case |
API_REQUEST_TIMEOUT | 300 seconds | Pulling multi-source due diligence data results in long interface response times, and the default timeout period is insufficient |
CUSTOM_FIELD_MAPPING | Auto-match by source data field names | Adapt to dynamic mapping needs for custom fields, with no need for hard-coded field correspondence |
MAX_BATCH_SIZE | 20 items | Control the number of due diligence reports pulled per batch to prevent timeouts caused by excessive data volume in a single request |
API_RETRY_TIMES | 3 times | Address temporary fluctuations in external data sources and reduce the probability of interface call failures |
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Parsing long-format due diligence reports takes extended time, so the timeout limit must be extended |
The parameter values provided on this page are all common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Calling an external interface returns
401 Unauthorized. The cause is that access permissions forAPI_KEYare not correctly configured, and the authorization scope for the corresponding due diligence data source is not bound. - Content returned after passing prompt variables does not match the due diligence theme. The cause is that the variable binding switch for
CUSTOM_FIELD_MAPPINGis not enabled, and interface return fields are not mapped to prompt placeholders. - Workflow debugging shows
504 Gateway Timeout. The cause is thatAPI_REQUEST_TIMEOUTis set too short and does not align with the pull time required for multi-source due diligence data.
How to Confirm Proper Configuration
- Call the test interface with standard-format due diligence data, and verify that returned fields match the mapping rules configured in
CUSTOM_FIELD_MAPPING. - Upload a single due diligence report of maximum allowed size, and confirm no
413 Request Entity Too Largeerror is triggered. - Initiate a batch pull request, and check that the number of returned due diligence reports meets the configuration requirements of
MAX_BATCH_SIZE. - Simulate a scenario where an external data source is temporarily unavailable, and confirm the interface triggers the retry logic defined by
API_RETRY_TIMESwith no direct error thrown.
