What the data for this category looks like
Advertising and marketing yield and daily market data primarily originates from official API endpoints of ad campaign management systems and media bidding platforms. Data updates once daily, usually completing full aggregation of the previous day’s full campaign data by 2 AM local time on the current day. A single daily report document includes core fields such as campaign channel identifier, impressions, clicks, conversions, total campaign cost, total revenue, and daily return on investment. The delivery_date field uses an ISO-formatted date string. The units for total_spend and total_revenue are Chinese Yuan. The daily_roi field uses a floating-point number format for the return on investment ratio. Different advertising channels have minor differences in returned fields; some channels will additionally return segmented campaign data for specific categories.
What constraints these characteristics impose on HTTP interfaces and external systems
Because data updates once per day, external systems must configure scheduled pull logic. High-frequency polling must be avoided to prevent unnecessary traffic pressure on advertising platform APIs. Advertising data comes from multiple sources. Different platforms have varying authentication methods and response formats. External systems must support adapting to multi-source interfaces and converting data formats. Daily report data includes multiple core business fields. Interface requests must support parameterized filtering to return only required fields and reduce transmission overhead. Data integrity directly impacts subsequent analysis. External systems must validate the presence and format of returned fields to avoid analysis errors caused by missing critical business data.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
SCHEDULE_CRON_EXPRESSION | 0 0 3 * * * | Ad platforms typically complete data aggregation for the previous day by 2 AM. Pulling data at 3 AM ensures all valid data is included |
API_RESPONSE_TIMEOUT | 15 seconds | Ad platform APIs respond slower during peak traffic. Allow sufficient time to avoid false timeouts |
FIELD_FILTER_ENABLED | Enabled | Reduce returned data volume and lower resource consumption during transmission and parsing |
CHANNEL_SPECIFIC_AUTH | Configure authentication parameters separately per channel | Different advertising channels have distinct authentication keys and request header formats. Separate configuration improves compatibility |
DATA_VALIDATION_RULES | Validate that delivery_date, total_spend, and total_revenue are required and have valid formats | Ensure the integrity and usability of daily report data, preventing invalid data from entering subsequent workflows |
ERROR_RETRY_TIMES | 3 retries | Address temporary network fluctuations or short-term jitters in ad platform APIs, reducing the probability of synchronization failures |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by data format, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test against your own samples before finalizing settings.
Three common mistakes
- Issue: A
404 Not Foundresponse is returned when executing a curl call to the interface. The cause is that the configured interface path does not include the full resource path of the advertising platform API, missing required suffixes such as/v1/report/daily. - Issue: An error
column vector does not existis displayed after connecting a vector database. The cause is failure to re-run the initialization script for the vector extension in PostgreSQL, or incorrect configuration of the extension installation path. - Issue: The
daily_roifield is empty in the daily report data pulled on a scheduled basis. The cause is failure to complete the mapping between the advertising platform's original fields and target fields in the interface mapping configuration, resulting in original data not being correctly mapped to the target field.
How to confirm configuration is complete
- Execute the pre-configured curl test command, check that the returned HTTP status code is
200 OK, and that the response body includes the expected core business fields. - Review the scheduled task run logs, confirm that interface call records exist at the configured trigger time, and that there are no errors related to authentication failure or timeout.
- Manually modify the simulated campaign data for a test channel, trigger the synchronization process, and check that the corresponding data in the target system is updated correctly.
- Check the stored data in the vector database, confirm that the
vectorfield has been generated as required, with no format abnormalities or missing entries.
