HTTP Interfaces and External Systems for Crop Farming

What Data for This Category Looks Like

Data sources for crop farming financing daily reports include publicly monitored data from agricultural and rural authorities, plus loan transaction records from agricultural financial institutions. Updates follow the natural daily cycle. Full data for the prior day is compiled each early morning. Deliverables use structured JSON or table formats. Core fields include standardized crop category names, six-digit administrative division codes, financing entity size tiers, single loan amounts, loan dates, and approved credit limits. Corresponding units are standardized category names, six-digit administrative division codes, large/medium/small/micro/individual labels, Chinese Yuan, YYYY-MM-DD formatted dates, and Chinese Yuan.

Constraints Imposed by These Characteristics for HTTP Interfaces and External Systems

Data sources include government regulatory interfaces and financial institution business systems. HTTP interfaces must comply with authentication rules for both system types. Government interfaces require government gateway signature verification. Financial interfaces must adapt to the OAuth2 authorization flow. Data updates daily on a natural day cycle. Interfaces must support date parameters to specify the daily report pull cycle. This supports scheduled pull scheduling needs. Fields include standardized crop categories, administrative division codes, and Yuan-denominated amounts. Interfaces must include built-in format validation rules. These rules block requests that fail coding standards, use crop categories not on the preset list, or have non-positive integer amounts. Data supports multi-dimensional filtering. Interfaces must include logic for combined multi-parameter queries. This prevents invalid requests from consuming system resources.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`API_REQUEST_TIMEOUT`	600 seconds	Crop farming financing daily report data includes cross-system aggregated content. A single pull may take a long time. 600 seconds covers the typical duration for full data pulls
`REQUEST_RETRY_TIMES`	3 times	Financial institution interfaces may experience temporary fluctuations. 3 retries reduce temporary failure rates without impacting business
`AUTH_TYPE`	Hybrid authentication	Government data sources require government gateway signatures. Financial data sources require OAuth2. Hybrid authentication supports multi-source access requirements
`QUERY_PARAM_FILTER`	Enabled	Filters invalid values for administrative division codes and crop categories. Prevents invalid requests from entering the data processing workflow
`PAGE_SIZE`	100 entries	Adapts to the default pagination limits of most HTTP interfaces. Balances the volume of data per request and response speed
`RESPONSE_PARSE_RULE`	Field mapping	Map the `province_code` returned by the interface to the system's `region_code` to ensure consistent data formats

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

Three Common Mistakes

Phenomenon: Significant differences exist between online chat and API call results for the same set of financing daily report data. Cause: The stream parameter is not set to false and the detail parameter is not set to true. This leads to inconsistent return formats compared to the structured results from online chat.
Phenomenon: A 400 error is returned when calling the interface. Logs contain request failed: Post "https://xxx". Cause: Correct authentication information for financial institution interfaces is not configured. The request URL has a spelling error, or valid date query parameters are not added.
Phenomenon: Empty or incorrectly formatted loan amount fields are returned by the interface. Cause: The QUERY_PARAM_FILTER configuration is not enabled. The amount field is not validated as a positive integer, leading to invalid data being integrated into the system.

How to Verify Proper Configuration

Initiate a single API request with the date set to the previous day. Confirm that returned fields match the RESPONSE_PARSE_RULE mapping rules preset in the system.
Simulate a temporary authentication failure scenario. Confirm the interface returns the corresponding error code after the request is triggered. This verifies that the authentication configuration is active.
Submit a request containing an invalid administrative division code. Confirm the interface blocks the request and returns a format error prompt.
Configure a scheduled pull task. Confirm the previous day's financing daily report data is automatically pulled the next morning. This verifies that the scheduling configuration is active.
