What Data in This Category Looks Like
Yield data for investment platforms comes primarily from exchange market data APIs, proprietary trading accounting systems, and user position data. Two update cadences apply: Real-time market data is pushed per second. Daily report data for daily yields and cumulative yields is generated in batch after market close each trading day. Single data records use a structured format, including fields such as product code, full product name, daily price change, 7-day annualized yield, net asset value per share, and daily trading volume. Yield-related fields use percentage units. Net value-related fields use CNY yuan. Trading volume fields can be marked in ten thousand yuan or yuan.
What Constraints These Characteristics Impose on HTTP Interfaces and External Systems
The second-level update frequency of real-time market data requires HTTP interfaces to support high-concurrency requests. This avoids data push delays caused by request backlogs. The batch generation feature of daily report data requires interfaces to support batch parameter input or paginated data pulling. This meets synchronization needs for daily full-volume data. The fixed post-market update cadence requires external systems to configure scheduled trigger logic aligned with the data update window. This prevents pulling ungenerated empty data. The fixed format of structured fields requires external systems to predefine field mapping rules. This adapts to numerical unit conversion and verification, and prevents synchronization failures caused by missing fields or format errors. Investment platform data typically includes authentication requirements. Interface calls must carry valid credentials. This avoids request interception from unauthorized access.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
request_timeout | 300 seconds | Adapts to the typical response delay of investment platform data interfaces, prevents batch pulling tasks from timing out |
max_retries | 3 times | Addresses temporary network fluctuations of market data interfaces, reduces synchronization failures caused by single jitter |
auth_type | API_KEY | Most investment platform public data interfaces use key-based authentication, complies with compliant data access requirements |
request_method | GET | Most investment platform market and daily report interfaces use GET to pass query parameters, aligns with standard interface specifications |
field_mapping_rule | One-to-one mapping by business field | Matches field names returned by investment platforms with internal system field definitions, supports unit conversion needs |
batch_size | 50 records per request | Balances interface load and synchronization efficiency, fits the batch pulling scenario for daily report data |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by data volume, business rules, and data form. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: HTTP interface calls return
401 Unauthorizedstatus code. Cause:auth_typeis not correctly configured asAPI_KEY, and a valid key is not passed. This does not meet the authentication requirements of investment platform interfaces. - Symptom: HTTP requests time out continuously, and data cannot be obtained. Cause: A reasonable
request_timeoutis not set, or a large number of concurrent requests are initiated at the same time. This triggers the rate limiting rules of the investment platform interface and causes requests to be rejected. - Symptom: Parsed yield data fields have abnormal formats and cannot be used normally. Cause:
field_mapping_ruleis not configured to adapt to the field names and units returned by the investment platform. Raw data is used directly, causing the internal system to fail to recognize percentage, net value and other formats.
How to Confirm Proper Configuration
- Initiate a single HTTP request, pass test product codes and query date parameters. Check that the returned response status code is
200 OK, and the response body contains expected fields. - Configure a scheduled trigger task, initiate batch requests after the investment platform data update window. Check that full daily report data can be pulled normally, with no empty responses or missing fields.
- Simulate network jitter scenarios, trigger the retry logic. Check that requests can recover automatically, with no task interruptions.
- Compare internal system fields with interface returned fields. Confirm that
field_mapping_rulehas completed mapping, and data units and formats meet the processing requirements of the internal system.
