What the Data for This Category Looks Like
Cosmetics profit margin and market trend data comes from e-commerce platform sales APIs, brand dealer inventory and sales APIs, and third-party industry monitoring APIs. Data is packaged in JSON format. Core fields include sku_id (unique SKU identifier), brand_name (brand name), product_category (product sub-category), reference_price (base price, unit: yuan), current_price (same-day selling price, unit: yuan), price_change_value (price change amount, unit: yuan), update_time (ISO format timestamp). Full data for the previous calendar day is compiled every early morning. In promotional periods, incremental updates are added to cover SKU information with temporary price adjustments.
Constraints Imposed by HTTP Interfaces and External Systems
Cosmetics categories have a large number of SKUs. Single requests must support batch pulling or pagination parameters. This avoids triggering third-party API rate limits due to excessive data volume in a single request. Two update modes exist for data: full and incremental. APIs must support filtering data ranges by timestamp. This adapts to daily full pulls and incremental syncs during promotional periods. Some niche brand SKUs may lack some industry monitoring fields. APIs must support null value returns. This prevents parsing exceptions. Data update times are fixed. External systems must configure scheduled tasks to trigger pulls at fixed daily times. This ensures access to the latest previous day's compiled data.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
HTTP_REQUEST_TIMEOUT | 30 seconds | Cosmetics category data APIs mostly handle batch SKU queries. 30 seconds covers request duration for most scenarios, and avoids interrupting data pulls due to timeout |
BATCH_REQUEST_SIZE | 50-80 | Cosmetics have a large number of SKUs. A single batch request size of 50-80 balances API load and pulling efficiency, and avoids triggering third-party API rate limits |
INCREMENTAL_SYNC_ENABLE | Enabled | Cosmetics have temporary price adjustments during promotional periods. Enabling incremental sync only pulls data from update periods, and reduces resource usage from full pulls |
REQUIRED_RESPONSE_FIELDS | sku_id, current_price, price_change_value, update_time | Profit margin reporting relies on these four core fields. Mandatory validation prevents reporting exceptions caused by missing critical data |
API_AUTH_MODE | API_KEY | Most cosmetics industry data APIs use API key authentication. Setting to API_KEY authentication ensures request legitimacy |
PARSE_RESPONSE_UNIT | Auto-match | Cosmetics price fields use yuan as the unit. Auto-matching avoids numerical calculation errors caused by manual unit configuration |
Three Common Configuration Errors
- Symptom: After upgrading to version 4.8.18, requests to cosmetics data APIs do not return historical same-period price data. Cause: The new version disables the historical data retrieval configuration switch by default. The corresponding parameter was not manually enabled.
- Symptom: Calling cosmetics data APIs returns a
400 Bad Requesterror, with a prompt indicating missing required fields. Cause: Required response fields were not fully configured inREQUIRED_RESPONSE_FIELDS, leading to API validation failure. - Symptom: After scheduled pull tasks run, price data for some promotional SKUs is not updated. Cause:
INCREMENTAL_SYNC_ENABLEwas not configured as Enabled. Only full data was pulled, which does not cover incremental update periods.
How to Confirm Proper Configuration
- A test request is sent to the configured cosmetics data API. Returned
sku_id,current_price, andupdate_timefields are verified for completeness and expected format. - Running logs of scheduled pull tasks are reviewed. Request time range parameters are confirmed to match preset update periods.
- A single batch pull request is initiated. The returned HTTP status code is checked to be
200 OK, and the number of returned entries falls within the range set byBATCH_REQUEST_SIZE. - Price values returned by third-party APIs are compared with parsed values within the system. Unit conversion is confirmed to be correct.
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Question material comes from public community discussions. Configuration values are common starting points and should be measured against your own samples. Verified on 2026-09-14.
