HTTP Interfaces and External Systems for IT Service Yield

What this category of data looks like

Data for IT service yield is sourced from the self-owned transaction accounting modules and compliance reporting interfaces of financial IT services. It synchronizes full accounting data for the previous trading day at a fixed time each day. The document structure uses a standardized structured data format. Each data entry includes a product unique identifier, accounting date, yield accounting value, and product classification tags. Field names follow financial industry data exchange specifications, with no extra nested levels. The data only includes legally completed accounting product information. It does not include real-time temporary transaction data.

What constraints these characteristics impose on HTTP Interfaces and External Systems

This category of data synchronizes full accounting data for the previous trading day at a fixed daily time. HTTP interfaces must support batch queries filtered by date range to avoid timeouts caused by excessive data returned in a single request. Data fields follow financial industry exchange specifications. External systems must strictly match preset field names when connecting, and cannot adjust mapping relationships arbitrarily. The data source includes compliance reporting interfaces. Interface requests must carry valid identity verification credentials, otherwise they will be blocked. In addition, there is an implicit upper limit on the amount of data returned per batch. External systems must split requests when calling, to avoid triggering traffic restrictions. Since the data only includes completed historical accounting data, the interface does not support real-time pulling of temporary data that has not been accounted for.

How to set configurations

Configuration Item	Recommended Value	Rationale
`request_timeout`	`600 seconds`	Full daily report data pulled in batches has a large volume, so sufficient timeout time is required to avoid request interruption
`batch_query_size`	`First 100 entries`	Excessive single batch data volume easily triggers interface current limiting. Splitting batches ensures request stability
`auth_token`	`Verification credential synced with compliance interface`	The data source includes compliance reporting interfaces, so valid identity credentials must be carried to pass verification
`cache_refresh_interval`	`86400 seconds`	Data updates once daily. Matching the cache refresh interval to the update cycle avoids obtaining old data
`field_mapping_mode`	`Strictly match preset fields`	Data fields follow financial industry exchange specifications. Custom mapping will cause field parsing failures
`rate_limit_threshold`	`10 times per minute`	The interface updates only once daily. Low-frequency calling avoids triggering current limiting policies

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

Three common mistakes

The phenomenon is returning a 401 Unauthorized status code when sending a POST request with curl. The cause is failing to carry the auth_token parameter required by the compliance interface, so identity verification fails.
The phenomenon is that the product_code field returned by the interface does not match the source data, with misalignment or garbled characters. The cause is not using the Strictly match preset fields mapping mode, and adjusting the field correspondence manually.
The phenomenon is triggering a 504 Gateway Timeout error when pulling data in batches. The cause is that the set request_timeout is too short to complete the full data pull.

How to confirm the configuration is complete

Send a single query request with a specified date range, and check if the returned fields match the preset product unique identifier, accounting date, and yield accounting value.
Send split batch requests, confirm that the number of returned results matches the batch setting, and no current limiting or timeout errors are triggered.
Wait for a full update cycle, then send a query again, confirm that the accounting date of the returned data is the latest previous trading day data.
Send a request with an unauthorized identity credential, confirm that a 401 Unauthorized status code is returned, to verify the validity of the identity configuration.
