Data Characteristics for This Category
Retail chain clinical trial pre-screening data originates from store sales systems, membership management systems, and online appointment platforms. This data typically stores in structured formats, such as JSON or XML. It includes patient age, gender, medical history (inferred from medication purchases in sales records), vital signs (such as self-test results from some stores), and contact information. Data updates frequently. Store sales data might synchronize in real-time. Membership information updates after each interaction.
Document structure usually follows retail industry data exchange standards. Field names are intuitive, for example, patientID, age, gender, medicationHistory. Units are clearly defined: age in "years", weight in "kilograms", and blood pressure in "mmHg".
Constraints from These Characteristics on "HTTP Interface and External Systems"
High update frequency of retail chain data requires the HTTP interface to handle high concurrency. This avoids data backlog and delays. Structured data enables interface design to focus on precise field mapping and data validation.
Data originates from multiple systems. The interface needs to support various authentication methods, such as API Key or OAuth 2.0. This ensures data transfer security. Standardized data fields help FastGPT accurately parse and identify entities upon data reception.
Large data volumes may occur. Interface response times require optimization. Support for pagination or incremental synchronization mechanisms might be necessary. For potential sensitive health data, the interface must strictly comply with data privacy regulations, including transmission encryption and access control.
Configuration Settings
| Configuration Item | Suggested Value | Rationale for Value |
|---|---|---|
API_KEY_HEADER | X-Retail-API-Key | Common custom header authentication method in retail chains |
BATCH_SIZE | 500 | Balances single request data volume and server processing capability |
REQUEST_TIMEOUT_SECONDS | 60 | Most retail system interface response times are 30-45 seconds |
MAX_RETRY_ATTEMPTS | 3 | Addresses network fluctuations or temporary service unavailability |
DATA_FORMAT | JSON | Mainstream data exchange format in retail chain systems |
ERROR_LOG_LEVEL | WARNING | Records non-fatal errors in detail for easier troubleshooting |
Three Common Mistakes
- The interface returns a
401 Unauthorizederror. TheAPI_KEY_HEADERkey name does not match the authentication header required by the external system. - Some patient information fields (e.g.,
medicationHistory) are empty. The external system interface might return a data structure inconsistent with FastGPT's expectations, leading to parsing failure. - Data synchronization is slow or times out. The
REQUEST_TIMEOUT_SECONDSvalue might be too low. It does not account for the time required by the external system to process batch requests.
How to Confirm Proper Configuration
- Perform a small-batch data synchronization. Check FastGPT console logs. Confirm no
4XXor5XXstatus code interface errors appear. - Randomly select 5-10 records from the external system. Compare field values with corresponding knowledge base entries in FastGPT. Confirm data completeness and correct format.
- Simulate high-concurrency requests. Observe FastGPT's resource usage and interface response time. Ensure system stability under expected load.
