What data for this category looks like
Data for this category covers production and compliance documents from manufacturers of single-use consumables, implanted and interventional devices, and similar products. Included documents are production process specifications, batch production records, clean zone environmental monitoring records, sterilization batch records, test reports, and more. Data sources include design history files, device and material batch ledgers, MES systems, clean environment monitoring equipment, sterilization equipment, and calibration and testing systems. Update frequency follows either per-batch or per-product record generation, or regular synchronization per environmental monitoring plans. Each individual document includes fields such as unique device identifier, batch number, temperature and humidity parameters, sterilization parameters, software version, and more. Fields must meet controlled requirements, and some traceability-related fields must be linked to full production process information.
What constraints these characteristics impose on the "HTTP Interfaces and External Systems" link
The multi-source, decentralized data sources for this category require HTTP interfaces to support integration with different types of external systems. Compliant authentication parameters must be configured to complete identity verification and prevent sensitive compliance data leaks. The batch-based or regular update rhythm requires interface calls to adapt to batch requests or triggers by specified batch numbers, to avoid timeouts caused by excessive data volume in a single request. Strict traceability field requirements mandate that response data returned by the interface fully include required fields such as unique device identifier and sterilization parameters, and field formats must match local document structures. Errors may trigger compliance or security issues, so clear failure retry and log recording mechanisms must be configured.
The following configurations apply to FastGPT v4.17.0.
How to set the configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Request timeout period | 300–600 seconds | Adapt to the data volume of single-batch documents for this category, avoid timeouts caused by overly long data pulling |
| Authentication parameter configuration | Fill in the Authorization parameter as required by the system | Complete identity verification when integrating with external compliance systems, in line with data security requirements |
| Global variable assignment | Pass fields such as batch number and unique device identifier | Adapt to batch-triggered interface calls, match the data update rhythm of this category |
| Single request data volume | 800–1200 characters | Control the size of returned data per single request, avoid exceeding limits set by external systems |
| Response data validation | Validate required fields in responseData | Ensure returned data includes key information required for traceability, meet compliance requirements |
| Retry count | 2–3 times | Address short-term external system fluctuations, reduce the risk of production interruptions caused by a single failed call |
Three common mistakes
- Symptom: An HTTP module call returns a connection timeout or status code 401, but the call works normally in Postman. Cause: The
Authorizationparameter is not configured correctly, or the FastGPT request header format does not match the authentication requirements of the external compliance system. - Symptom: The interface call returns a parameter format error prompt, and data cannot be obtained normally. Cause: Required fields such as batch number and unique device identifier for this category are not passed via
variables, resulting in request parameters that do not match the requirements of the external system. - Symptom: After adding an HTTP request to a loop nest, the number of returned results does not match expectations or duplicate data appears. Cause: No batch filtering rules are configured within the loop, resulting in repeated pulling of document data for the same batch.
How to confirm the configuration is correct
- Manually pass a preset batch number, initiate an HTTP request via FastGPT's debugging tool, and check if the returned
responseDataincludes required fields such as device identifier and sterilization parameters. - View FastGPT's request logs to confirm that the
Authorizationparameter is correctly carried and that the request header format matches the requirements of the external system. - Adjust the timeout period to 600 seconds, initiate a batch request test, and confirm that no timeout errors occur.
- Add an HTTP request to a loop nest, pass different batch number parameters, and check if the returned results correspond to document data for different batches.
