What this category of data looks like
Business data for coal transportation and sales primarily comes from weighbridge tickets, railway/road waybill systems, scheduling and rostering systems, and financial settlement systems. Data update rhythms fall into three categories: real-time updates for weigh weight and shipment time, daily updates for that day’s shipment volume statistics, and monthly updates for settlement unit prices and reconciliation data. Each individual business document includes fixed fields such as waybill number, coal type, net weight (unit: ton), origin, destination, carrier, and settlement unit price (unit: yuan/ton). Some cross-department collaboration data also includes an approval status field.
What constraints do these characteristics impose on the "HTTP Interfaces and External Systems" link?
The multi-source, time-staged update nature of coal transportation and sales data requires interfaces to support filtered queries by business dimensions such as coal type and shipment cycle, to avoid redundant traffic from full-volume pulls. The high-frequency updates of real-time weighbridge data require interface timeout settings to accommodate cross-system data aggregation time, and should not be too short. The clear fixed fields require interface returned data to accurately map business fields, avoiding invalid fields interfering with parsing by internal office systems. Sensitive data from cross-system collaboration requires strict configuration of interface identity verification to prevent unauthorized access.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {API key generated by the platform} | Coal transportation and sales data involves sensitive production and financial information, so this parameter is required for strict identity verification |
variables | Pass coal type and weigh time range as query variables | Adapt to the core office requirement of filtering business data by category and cycle for coal transportation and sales |
responseData | Specify return fields including waybill number, net weight, origin, and settlement unit price | Reduce invalid data transmission and adapt to the data parsing logic of internal office systems |
| Single request timeout | 600 seconds | Cross-system data aggregation queries take a long time, avoid request interruption due to timeout |
| Interface polling interval | 30–60 seconds | Real-time weighbridge data needs to be synchronized to internal office systems in a timely manner; an interval that is too long will not meet timeliness requirements |
Three common mistakes
- Phenomenon: When calling the
/api/v1/chat/completionsinterface, the knowledge base uploaded coal transportation and sales business documents cannot be associated after configuring appId. Cause: No exclusive classification tag for business data specified invariables, resulting in incomplete coverage of knowledge base recall scope. - Phenomenon: Interface returns 514 status code. Cause:
Authorizationparameter not configured correctly, or the API key does not have data access permission for the corresponding system. - Phenomenon: The number of conversation records returned after calling the interface is lower than expected. Cause: Requests not split by batch dimension of business data, single returned data volume exceeds the system default limit.
How to confirm configuration is complete and correct
- Send a test request, check if
responseDataincludes preset fields such as waybill number and net weight, and that field values match actual business data. - Call the interface to obtain conversation records, confirm that the number of returned entries matches the preset pagination logic, with no truncation or omissions.
- Simulate an abnormal request with an expired key, confirm that identity verification-related errors are returned, and no exceptions other than 514 status code occur.
- Synchronize real-time weighbridge data, check that the update time returned by the interface matches the actual weigh time, with no obvious delay.
