HTTP Interface and External Systems for After-Sales and

Data Characteristics in This Category

After-sales and warranty data in the biomedical field originates from CRM systems, ERP systems, product traceability platforms, and patient feedback databases. This data updates frequently. Product recalls, batch updates, and repair status feedback often require near real-time synchronization. Document structures include structured warranty card information, repair logs, adverse event reports, and product manuals in PDF format. Unstructured data includes patient inquiry emails, transcribed phone recordings, and social media comments. Specific fields include product_batch_id, production_date, expiration_date, medical_device_registration_number, patient_medical_record_number (anonymized), repair_part_serial_number, fault_code, and diagnosis_report. Units include dosage units (mg, ml), time units (year, month, day, hour), temperature units (℃), and specific test indicator units.

Constraints from "HTTP Interface and External Systems"

The diverse and time-sensitive nature of after-sales and warranty data imposes specific requirements on HTTP interface design. Structured data, such as warranty records and repair progress, requires precise query and update capabilities via RESTful API or SOAP interfaces to ensure data consistency. Unstructured data, like patient feedback, needs document upload interfaces that efficiently parse various formats (PDF, DOCX). Due to patient privacy, interfaces must use HTTPS for data transmission and implement strict authentication and authorization using OAuth2.0 or API Keys. High update frequency demands batch and incremental update capabilities to avoid resource waste from full synchronization. Finally, specific field requirements mean interface parameters must explicitly define biomedical fields, such as product_batch_id and device_serial_number, and validate units to prevent data misinterpretation.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`HTTP_METHOD`	`POST` or `GET`	Select based on the business scenario. Use `GET` for querying warranty information, `POST` for submitting repair orders.
`API_ENDPOINT`	`https://api.example.com/v1/warranty`	Points to the specific business system interface address, ensuring secure transmission.
`AUTH_HEADER_TYPE`	`Bearer Token`	Provides OAuth2.0-based security authentication, ensuring only authorized requests can access.
`REQUEST_TIMEOUT_SECONDS`	`60` seconds	Accounts for external system response times and data volume, preventing poor user experience due to long waits.
`RETRY_COUNT`	`3` times	Handles network fluctuations or transient external system failures, improving interface call stability.
`RESPONSE_PARSER_TYPE`	`JSONPath` or `XPath`	Selects the appropriate parsing method based on the external interface's return data format (JSON or XML).

Common Pitfalls

External system API calls return 401 or 403 errors because the Bearer token in the Authorization request header is expired or malformed.
The batch_number field is empty when querying warranty information. This might be due to a mismatch between the external system's field name and the JSONPath configured.
The external system does not create a corresponding work order after a repair request submission. This might be because the device_serial_number field in the request body has an incorrect data type (e.g., a number sent when a string is expected).

Verification Steps

Use FastGPT's debugging feature to send simulated requests to the configured HTTP interface. Check for a 200 status code and confirm the response data contains expected key fields.
Trigger smart customer service scenarios that call the external interface during actual conversations. Verify that the smart customer service correctly extracts user intent and passes parameters, and that the external system receives the request and returns correct results.
Monitor external system logs to confirm FastGPT requests are received and processed correctly. Check that request parameters (e.g., product_id, warranty_status) match expectations.
Regularly check the validity of the Bearer Token or API Key used in AUTH_HEADER_TYPE to ensure authentication credentials remain active.
