What this category of data looks like
Steel trade financing daily report data is sourced from internal inventory and sales management systems of steel trading enterprises, credit ledgers of partner banks, and same-day cargo right pledge registration systems. Data is synced daily at midnight with complete data from the previous working day. Each daily report has a fixed structure, including the following fields: trading entity name, steel product grade and specification, daily outbound and inbound volume, corresponding financing credit limit, total value of pledged goods, and progress of due payment recovery. The steel product grade and specification field must include grade and specification model. Quantity units are tons. Monetary field units are yuan or ten thousand yuan.
Constraints imposed on HTTP interfaces and external systems
Since data is sourced from multiple internal and external systems, interfaces must support identity verification and permission isolation across multiple data sources to prevent cross-entity data leaks. The fixed daily update rhythm requires that scheduled call configurations for interfaces align with the midnight sync window, and support incremental pulling of updated entries to reduce transmission load. The complex structure of the steel product grade and specification field requires interface parameter validation rules to cover format checks for grade and specification model, preventing invalid data from being stored. Fixed units for quantity and monetary values require interfaces to enforce unit consistency checks for request parameters, avoiding data deviations caused by unit conversion errors. The large volume of daily report data for multiple trading entities requires interfaces to support pagination return parameter configurations to adapt to business requests of different scales.
How to configure settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_DOC_TIMEOUT | 300 seconds | A single steel trade financing daily report includes multiple types of detailed fields, with longer parsing time than general documents. 300 seconds covers the complete parsing process |
ALLOWED_DOC_EXTENSIONS | xlsx, csv, pdf | Common formats for steel trade financing daily reports are Excel ledgers, CSV export files, and PDF scanned documents, covering mainstream submission formats |
API_REQUEST_SIGNATURE | Enable HMAC-SHA256 | When connecting to multiple bank and internal systems, signature verification prevents request tampering and ensures data security |
MAX_BATCH_SIZE | 50 items per request | Single batch request volume aligns with the daily submission scale of steel trading enterprises, avoiding interface overload |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Daily report files containing multiple batches of steel inventory details have large file sizes. 1000 MB covers most submission scenarios |
VALIDATE_FIELD_SCHEMA | Enable mandatory validation | Field formats such as steel product category and monetary unit are fixed. Mandatory validation filters invalid submission data |
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. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Issue: API interface returns
Invalid URL, code: 500when uploading a financing daily report file. Cause: The request address is configured as a local debug addresshttp://localhost:3000/..., and has not been replaced with the official domain name accessible in the production environment. External systems cannot resolve local addresses. - Issue: HTTP tool sets return empty fields when calling the interface. Cause: Interface parameter validation rules are not correctly configured, and mandatory checks for required fields such as steel product category and unit are not enabled. Invalid requests are accepted but do not return valid data.
- Issue: Timeouts occur when synchronizing financing daily report data on a scheduled basis. Cause: The
PARSE_DOC_TIMEOUTconfiguration is not adjusted, and the default timeout period is insufficient to complete parsing of daily report documents containing multiple batches of details.
How to verify correct configuration
- Send a single test request with standard-format steel trade financing daily report data, and verify that the returned parsing results match the original data fields.
- Configure a scheduled trigger task aligned with the daily midnight update window, and verify that task execution logs show successful synchronization.
- Upload a test file of the maximum single volume, and verify that the interface completes parsing within the preset timeout period.
- Simulate multiple batch requests, and verify that the paginated data returned by the interface fully covers all entries.
