HTTP Interfaces and External Systems for E-commerce Service

What this category's data looks like

Data for e-commerce service financing daily reports comes from e-commerce platform merchant settlement systems and financing approval and loan transaction records from cooperating financial institutions. A full daily report file is generated the day after natural day trading concludes. Data is delivered as structured JSON or CSV files grouped by unique merchant identifier. Included fields are: merchant ID, total daily transaction amount, number of daily financing applications, approved quota, actual loan amount, and loan completion time. Corresponding units for each field are: string, yuan, count, yuan, yuan, and hour.

Constraints for HTTP interfaces and external systems

Because data comes from multi-system financial transaction records and is generated in daily batches, HTTP interfaces must support precise pulling of target daily report data using natural date parameters. The unique merchant identifier field requires the interface to support precise filtering by merchant ID, to avoid returning unrelated data. Data includes financial amount fields, so interfaces must return structured fields with clear units, and must not omit unit information. Daily data volume fluctuates with merchant scale, so interfaces must support pagination queries or segmented returns. This prevents transmission failures or interface overload caused by excessively large single-request data sets. Financial data requires encrypted transmission, so interfaces must enforce use of the HTTPS protocol.

Configuration settings

Configuration Item	Recommended Value	Rationale
`api_request_timeout`	`600 seconds`	E-commerce financing daily report data volume fluctuates. 600 seconds covers the time required for full data pulling, and avoids request interruption due to timeout mid-transfer.
`auth_type`	`signature`	Financing daily report data belongs to financially sensitive information. Signature authentication verifies request legitimacy, preventing unauthorized access and data leaks.
`data_fetch_date_format`	`YYYY-MM-DD`	Daily reports are generated per natural day. This format fully matches the date naming rules of the data source, allowing precise location of daily report files for the target date.
`response_field_include_unit`	`true`	Data source fields come with unit information. Retaining units ensures data readability and accuracy of business semantics.
`pagination_enable`	`true`	Number of merchants per day varies. Pagination queries prevent transmission failures or interface overload caused by excessively large single return data volumes.
`request_method`	`GET`	Pulling daily report data is a read-only operation. GET requests conform to HTTP semantic specifications, and facilitate parameter splicing and debugging troubleshooting.

The parameter values provided on this page are common starting points 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 misconfigurations

Symptom: The interface returns {"code":514,"statusText":"invalid auth"}. Cause: Authentication parameters are not configured correctly, or the signature generation logic does not match the requirements of the data source.
Symptom: The interface returns empty financial amount fields. Cause: The response_field_include_unit configuration is not enabled, or the filtered merchant ID has no corresponding financing record in the daily report for that day, and the null value return switch is not configured.
Symptom: The interface request times out. Cause: The api_request_timeout configuration is not set to a value matching the data pulling time, or a single request pulls daily report data for multiple days, exceeding the single request limit of the interface.

How to verify correct configuration

Run a curl command to call the interface, pass correct date and merchant ID parameters, check that the returned HTTP status code is 200.
Review the interface returned fields, confirm that expected fields such as merchant ID, transaction amount, and financing quota are included, and that amount fields have attached corresponding units.
Simulate requests for multiple dates, check that the interface accurately returns daily report data for the specified date, with no cross-day data included.
Trigger authentication failure or parameter error scenarios, check that corresponding error codes and prompt messages are returned, verifying that the verification logic is active.
