HTTP Interfaces and External Systems for Telecommunications

What this category of data looks like

Data for telecommunications service intelligent due diligence reports primarily comes from operator business support systems, telecommunications industry regulatory platforms, and enterprise-owned telecommunications operation and maintenance systems. There are two types of data update cycles: real-time call detail records and traffic usage data are updated minute-by-minute, while qualification compliance and business license data are updated daily. The document structure includes four content categories: basic subject information, communication link indicators, compliance rectification records, and customer communication behavior details. Exclusive fields include bandwidth_usage (unit: Mbps), service_license_expire_date (ISO date format), and compliance_score (percentage-based value). A single report may include structured data and attachments such as topology diagrams, and data volume increases with the scale of service coverage.

What constraints do these characteristics impose on HTTP interfaces and external systems

The two update cycles of telecommunications service due diligence data require splitting interfaces into two separate links: real-time data pulling and batch data synchronization. This prevents high-frequency real-time requests from occupying batch interface resources. The high-frequency call nature of real-time data requires external systems to support short connection concurrent processing. A reasonable concurrency upper limit must also be configured. Exclusive fields and unit rules require that interface returned fields strictly match telecommunications service naming specifications. Additional field unit verification logic must be added to avoid parsing errors. Compliance requirements are relatively high. External system integration must add security mechanisms such as signature verification and IP whitelists. Single reports have large attachment sizes. Interface response size limits must be adjusted to accommodate complete data pulling.

How to set configurations

Configuration Item	Recommended Setting	Rationale
`external_api_url`	Fill in the exclusive interface address for telecommunications service due diligence data	Telecommunications service due diligence data must be obtained from dedicated interfaces of operators or regulatory platforms, and general data sources cannot be used
`api_request_timeout`	`300-600 seconds`	Batch telecommunications qualification reports include detailed call records and topology diagrams, which take a long time to pull. A long timeout setting must be adapted
`field_mapping_rule`	Map according to telecommunications service exclusive fields, such as mapping `bandwidth_usage` to "communication bandwidth usage"	Telecommunications due diligence reports have standardized field naming and unit rules. Strict matching is required to avoid parsing errors
`api_signature_method`	`HMAC-SHA256`	Telecommunications data involves operator compliance information. Signature verification is required to ensure the security of interface calls
`batch_sync_interval`	Real-time data: `60 seconds`, batch compliance data: `86400 seconds`	Match the update cycle of telecommunications service data. Real-time call detail records require high-frequency synchronization, while qualification data is updated daily
`max_response_size`	`100 MB`	The maximum volume of attachments (such as link topology diagrams, detailed reports) for a single telecommunications due diligence report conforms to industry general standards

The parameter values provided on this page are all conventional recommendations used as a starting point 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

Symptom: Calling the application history interface returns 401 Unauthorized, and credentials are confirmed to be correct. Cause: The exclusive signature key for telecommunications service interfaces was not used, and general API keys were mistakenly used for verification.
Symptom: The unit of pulled communication bandwidth data is parsed abnormally, displayed as GB, while the correct unit should be Mbps. Cause: Field unit verification configuration was not enabled, and mapping logic was not configured according to telecommunications service exclusive field rules.
Symptom: The number of recalled due diligence reports does not match the number returned by the actual interface. Cause: The configured pagination parameters do not match the pagination parameter naming requirements of the telecommunications interface. pageSize required by the telecommunications interface was mistakenly written as size, leading to abnormal pagination logic.

How to confirm that the configuration is correct

Call the configured HTTP interface, check whether the returned fields include telecommunications service exclusive fields such as bandwidth_usage and compliance_score, and whether the units meet expectations.
Initiate a batch data pull request, check whether resumable upload is supported, and no mid-process interruptions or timeouts occur.
After configuring signature verification, initiate a request with a valid signature, confirm that the return status code is 200 OK, and requests with invalid signatures return 401 Unauthorized.
Check the system operation log, confirm that the interface request timeout falls within the configured 300-600 seconds interval, and no early termination occurs.
