HTTP Interfaces and External Systems for In-App Natural

What data for this category looks like

Data for this category comes from end-user natural language interaction logs. It includes retrieval requests initiated by users within finance and insurance applications, viewed historical content, and associated operation records. Updates are generated in real time: one new record is added after each user interaction.

Each document has fixed fields: session_id (string, unique session identifier), user_id (string, user account identifier), query_content (text, retrieval content entered by the user), query_timestamp (integer, millisecond-level timestamp), operate_result (text, core content summary returned by the retrieval).

No additional aggregation attributes exist for any fields. Only complete information for a single interaction is recorded.

What constraints these characteristics impose on HTTP interfaces and external systems

The real-time update feature of this category requires HTTP interfaces to support high-frequency concurrent writes, to avoid lost or delayed interaction data. Strict validation rules for fixed fields require interfaces to perform format checks on required fields including session_id, user_id, and query_timestamp. query_timestamp must strictly match the millisecond-level timestamp specification to prevent field parsing errors.

There is no fixed upper limit on the text length of query_content and operate_result. Interfaces must configure reasonable request body size limits to avoid connection timeouts caused by large text content. Additionally, since the data is associated with user privacy and financial transaction information, interfaces must integrate a unified authentication module to ensure the legality of external system calls.

How to set configurations

Configuration Item	Recommended Value	Rationale
`API_REQUEST_TIMEOUT`	`30 seconds`	The processing flow for a single interaction data entry in this category is short. 30 seconds covers the full process of authentication, field validation, and data writing, avoiding call failures caused by timeouts
`REQUIRED_FIELDS`	`["session_id", "user_id", "query_timestamp"]`	Core identification fields for this category's data. Missing these fields makes it impossible to accurately associate user interaction records with retrieval behaviors
`MAX_REQUEST_BODY_SIZE`	`2048 KB`	`query_content` and `operate_result` may contain lengthy text content. 2048 KB covers most business scenarios
`AUTHENTICATION_MODE`	`API_KEY`	Meets security requirements for financial scenarios. API_KEY authentication quickly verifies the legality of external system calls
`LOG_RETENTION_DAYS`	`180 days`	Complies with data retention compliance requirements for the financial industry. Retains interface call logs for a sufficient duration to support troubleshooting
`BATCH_INSERT_LIMIT`	`10 entries`	Balances interface call efficiency and database load. Batch writing 10 entries reduces resource consumption caused by high-frequency calls

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.

Three common mistakes

Symptom: Interface calls return a 401 Unauthorized status code, or configuration test pop-ups report errors directly. Cause: AUTHENTICATION_MODE is not correctly set to API_KEY, or the passed authentication key format is incorrect, and a valid call credential is not carried.
Symptom: The specific cause of interface errors cannot be located, and no clear error log is output. Cause: Interface debug log configuration is not enabled, or the log retention duration is set too short, causing error information to be automatically cleared.
Symptom: Calling the /api/core/dataset interface with a curl command returns a 400 Bad Request status code. Cause: The request body does not include required fields defined in REQUIRED_FIELDS, or the query_timestamp parameter does not use the millisecond-level timestamp format.

How to confirm configurations are set correctly

Execute a test call that includes all required fields. Check that the interface returns a 200 OK status code, and the response body includes a success identification field.
View interface call logs to confirm that fields such as session_id, user_id, and query_timestamp from the test request are correctly parsed and recorded.
Initiate high-frequency calls from an internal or external system to verify that the interface's concurrent processing capability meets business expectations.
Modify the authentication key to an invalid value and initiate a call. Confirm that the interface returns a 401 Unauthorized status code to verify that the authentication configuration is active.
