HTTP Interfaces and External Systems for Gas Intelligent Due

What the Data for This Category Looks Like

Financial institutions performing intelligent due diligence on gas enterprises source most required data from gas operating enterprises’ SCADA monitoring systems, operation management systems, and municipal gas supervision platforms. Two update rhythms apply: real-time operating parameters such as pipe network pressure and flow are synced every second. Monthly and quarterly revenue, user growth, and safety inspection data update on fixed cycles. Most data uses structured fields, including station ID, supply pressure, daily gas supply, inspection time, hidden danger level, and others. Some fields follow gas industry standard terminology: pressure is measured in kilopascals (kPa), gas volume in cubic meters (m³), and hidden danger level is an enumerated value.

Constraints on HTTP Interfaces and External System Integration

When financial institutions integrate with external gas enterprise systems to obtain due diligence data, the characteristics of gas data impose multiple constraints on HTTP interface and external system connections. High-frequency real-time operating parameter updates require interfaces to support high-concurrency calls. Reasonable current-limiting rules must be configured to avoid system overload. Industry standard requirements for structured fields mean interface returned field names, units, and enumerated values must align with gas industry specifications. Non-compliant values will cause downstream parsing errors. Combined long-text inspection reports and multi-dimensional data increase single-request data volume. Sufficient response time and transmission space must be reserved. Cross-system integration must comply with gas enterprise data security specifications. Unified authentication methods must be configured to ensure compliant data access.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`external_api_timeout`	`180 seconds`	Gas due diligence data includes long-text inspection reports and multi-dimensional operating parameters. Single request data volume is large, so sufficient response time must be reserved
`external_api_auth_type`	`API_KEY`	Most gas operation systems use API key authentication, which complies with industry data access security specifications
`external_data_batch_size`	`50 items per request`	Real-time operating data of gas pipe networks is pushed in batches. Single batch data volume should not be too large to avoid excessive interface load
`api_response_max_size`	`10 MB`	The total sum of structured data and attached text of a single gas due diligence report usually does not exceed this threshold, preventing transmission failures
`retry_on_fail_threshold`	`2 retries`	Real-time performance requirements for gas data are high. Retrying in case of minor network fluctuations reduces request failure rates and avoids impacting due diligence processes

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 individual analysis. It is recommended to test on your own samples before finalizing values.

Three Common Misconfigurations

Scenario: Interface returns 413 Request Entity Too Large status code. Cause: The api_response_max_size configuration was not adjusted. Gas due diligence reports include large amounts of base64-encoded inspection image data, exceeding the default interface response size limit.
Scenario: The hidden danger level field returned by the interface is empty. Cause: Correct authentication parameters were not configured in external_api_header_params. The gas operation system blocked unauthorized requests and did not return complete data fields.
Scenario: Due diligence knowledge base data lags behind external systems. Cause: The synchronization interval matching the gas data update cycle was not configured. Knowledge base refresh was not triggered on a fixed cycle, resulting in delayed updates of report data.

How to Verify Proper Configuration

Call the test interface and confirm that the returned gas operating parameter fields include correct units and enumerated values that match industry standard terminology.
Check interface call logs to confirm that request frequency complies with configured current-limiting rules, and no frequent 429 Too Many Requests errors occur.
Trigger a knowledge base synchronization task and confirm that updated due diligence report data matches the latest data from external systems.
Simulate a single high-volume request to confirm that the interface does not trigger 413 or 504 Gateway Timeout status codes, and response time meets the configured timeout threshold.
