What Data for This Category Looks Like
Funding source KYC data has two core forms: structured and unstructured. Structured data refers to bank transaction statements generated by banks or payment institutions. Its fields include transaction date, transaction amount, transfer-in/transfer-out accounts, transaction remarks, account balance, etc. Units are RMB yuan and standard date formats. Unstructured data refers to supporting certification materials such as income certificates, tax returns, and scanned transfer vouchers. Data is updated either as a static submission for a single verification, or as cumulative transaction records synced on a fixed cycle. Single documents typically have 10 to 50 pages, and the core field structure is relatively stable.
What Constraints Do These Characteristics Impose on Tool Calling and Plugins?
The dual form of funding source KYC data requires tool calling to support both unstructured document parsing and structured field extraction. Some verification scenarios require cross-institution transaction record retrieval, so plugins must adapt to multi-source authentication and cross-domain request logic. The relative stability of core fields requires precise specification of extraction scope during tool calling, to avoid redundant data interfering with verification workflows. The page limit per document requires the tool call timeout parameter to adapt to long text processing needs, while controlling call frequency to avoid triggering data source rate limits.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
tool_call_timeout | 300 seconds | Funding source verification documents may contain multi-page transaction statements, and parsing and cross-source querying take a long time. 300 seconds covers conventional processing workflows |
max_extract_fields | 10–15 fields | The core fields for funding source verification include transaction date, transaction amount, account information, etc. 10 to 15 fields cover all verification requirements without redundancy |
plugin_auth_type | api_key authentication | Most financial data source APIs use API key authentication, and this configuration directly adapts to the authentication process for standard plugin calls |
parse_file_max_pages | 50 pages | The number of pages in regular corporate funding transaction statements does not exceed 50. Pages beyond this usually contain non-core verification information, reducing invalid processing |
response_return_mode | Return structured results only | Funding source verification only requires extracting specified fields. This configuration filters unstructured text from the original plugin response |
api_request_rate_limit | 10 requests per minute | Financial data source APIs usually have call frequency limits. 10 requests per minute avoids triggering rate limit errors |
The parameter values provided on this page are common recommendations for establishing configuration baselines. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Custom Python function calls return
504 Gateway Timeout. Cause: Thetool_call_timeoutparameter is not set, or its value is too short to complete long document parsing and field extraction. - Symptom: Plugin calls return
401 Unauthorized. Cause: A globally shared API Key was used instead of an application-specific API Key, or plugin authentication parameters were not configured correctly. - Symptom: Tool call results include knowledge base search content. Cause: The knowledge base recall switch was not disabled in the workflow, or
response_return_modewas not set to Return structured results only.
How to Verify Proper Configuration
- Upload a single-page funding transaction statement, run the workflow, and check if the fields returned by the tool call match the preset extraction fields.
- Call the test financial data source plugin, check if the returned HTTP status code is
200 OKand there are no authentication-related errors. - Review the workflow run logs to confirm no timeout errors related to
tool_call_timeoutwere triggered. - Cross-check the tool call response content to confirm no knowledge base search input or output text is included.
