What this category’s data looks like
Data sources include business management systems of financial leasing institutions, order ledger modules of equipment dealers, and publicly registered data from the chattel financing publicity platform. Full financing records for the previous calendar day are updated daily at midnight. Most documents use structured JSON or CSV formats. Core fields include: device_sn (unique device serial number, string type), device_model (device model, string), financing_amount (financing amount, in yuan, numeric value with two decimal places), loan_date (loan date, ISO 8601 format string), lease_term (lease term, in months, positive integer), lessee_name (full lessee name, string). Some records include additional fields such as device rated power and manufacturer.
What constraints these characteristics impose on HTTP interfaces and external systems
device_sn serves as the core unique identifier. HTTP interfaces must support batch pulling or precise query by device_sn to avoid duplicate entry of financing records. Financing amounts use a numeric format with two decimal places. Interfaces must disable scientific notation during transmission, and explicitly specify numeric precision. The daily update schedule requires external synchronization tasks to trigger at daily midnight. Interface request date parameters must be limited to the previous calendar day range. Differences in fields across multiple data sources require interfaces to support custom field mapping. This adapts to different field naming rules of financial leasing systems and chattel publicity platforms. Some devices have missing fields for additional financing information. Interfaces must configure fault tolerance handling for optional fields to avoid request failure due to missing fields.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
request_timeout | 30 seconds | Financing daily report interface requests have moderate data volume. Most scenarios take no more than 20 seconds. Reserve 10 seconds of redundancy to avoid timeouts |
response_format | application/json | Financing daily reports use structured JSON format for transmission. Specifying this format allows direct parsing into callable workflow variables |
batch_query_size | 100 items per request | Complies with interface rate limiting rules of most financial leasing systems. Single batch data volume is controllable, avoiding interface return overload |
auto_date_range | Previous calendar day | Financing daily reports update with the previous day's data each day. Automatically populating the date range reduces the probability of manual configuration errors |
field_mapping | Custom mapping | Field naming varies across different data sources. Custom mapping aligns external fields to internal unified field identifiers |
missing_field_handle | Skip and log | Some devices have missing fields for additional financing information. Skipping requests with missing fields avoids overall task interruption |
The parameter values provided on this page are common recommended starting points for configuring settings. 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 settings.
Three common mistakes
- Symptom: HTTP interface returns
400 Bad Requesterror with promptinvalid date format. Cause: Theloan_daterequest parameter does not use ISO 8601 format. For example, passing a date inYYYY/MM/DDformat does not meet interface specification requirements. - Symptom: Numeric precision of the
financing_amountfield is lost after a workflow calls the interface. Cause: No numeric parsing rule is specified for the interface response. The default parsing uses integer type, resulting in truncation of amounts with two decimal places. - Symptom: BLOB-format financing attachment data is obtained via the HTTP node in a workflow, and no download entry can be provided in the dialogue interface. Cause: No response content saving rule is configured for the HTTP node. Binary data is not stored as an accessible file object, making download link generation impossible.
How to confirm correct configuration
- Manually trigger an HTTP request. Check if the returned JSON data includes all configured mapping fields, and that field formats meet expectations.
- View workflow run logs. Confirm no error prompts such as
invalid date formatormissing fieldappear. - Configure a scheduled synchronization task. Wait for the automatic trigger the next day, then check if synchronized financing daily report data covers all records from the previous calendar day.
- Test relevant nodes in the dialogue interface. Confirm structured financing daily report data can be normally obtained and displayed.
