HTTP Interfaces and External Systems for Sanctions List Screening KYC

Sanctions list screening data primarily originates from sanction lists, politically exposed persons (PEP) lists, and terrorist-related entity lists

What the data for this use case looks like

Sanctions list screening data primarily originates from sanction lists, politically exposed persons (PEP) lists, and terrorist-related entity lists published by national financial regulatory authorities and international organizations. Data update schedules align with regulatory announcements. Standard scenarios use daily full update package syncs. Incremental updates are pushed when emergency sanction events occur. Each data entry includes fields such as entity ID, name, alias list, nationality, document type and number, affiliated institutions, effective date, and publishing authority. The aliases field uses array format. The effective_date field follows the ISO 8601 date format. No custom units are used.

Constraints for HTTP interfaces and external systems

Full data update packages have large volume and contain sensitive entity information. HTTP interfaces must support breakpoint resuming and transmission encryption to prevent data leaks or transmission interruptions. The array-format alias field requires interface parameters to support multi-value matching queries. External integration systems must adapt to array-type request bodies and response structures. Uncertainty in regulatory updates requires integrated scheduled tasks to support dynamic adjustment of pull intervals. Complete call logs and return results must be recorded to meet compliance audit requirements. Unique verification of entity document number fields requires interfaces to support exact matching queries, avoiding misjudgment risks from fuzzy matching.

Configuration Settings

Configuration ItemRecommended ValueRationale
request_timeout300 secondsSanctions list data queries involve multi-field matching and full validation, leading to longer average interface response times
batch_query_size20-50 entriesExcessively large single-batch query volumes may trigger interface rate limits. Excessively small volumes increase the number of calls
update_sync_modeIncremental pullFull pull takes too long. Incremental updates align with the rhythm of regulatory real-time announcements
ssl_verifyEnabledFinancial compliance data transmission requires certificate validation to ensure data security
log_retention_days180 daysFinancial anti-money laundering compliance requirements mandate retaining at least six months of call logs
field_mappingMap by entity document number + nameThe core matching dimensions for sanctions list data are the combination of document number and name, preventing mis-matches from single fields

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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Configuration Mistakes

  • A 400 Bad Request response with no response body occurs when the incoming aliases array format does not meet interface requirements. This includes failure to properly serialize the request body or pass array parameters as specified.
  • Scheduled pull tasks frequently trigger interface rate limits. This happens when the pull interval is not set according to the regulatory update rhythm, and the full pull frequency is set to an overly short cycle.
  • Matching result counts do not match expectations. This occurs when the field_mapping parameter is not configured, and only single-name field matching is used, missing entities associated with aliases.

How to Verify Proper Configuration

  • Initiate a single test call with known test entity information. Verify that the returned results include matching list entries.
  • Check interface call logs to confirm that the request body field format aligns with the configured field_mapping rules.
  • Verify the trigger interval of the scheduled pull task to confirm it matches the configured update_sync_mode.
  • Check the encryption status of the transmission link. Confirm that the ssl_verify configuration is active, with no certificate validation errors.
