What the data for this category looks like
Shipping port financial report data mainly comes from official public statistical reports from port authorities and monthly port industry monitoring data from the Ministry of Transport. Update cycles follow monthly, quarterly and annual core periods. Some real-time operation data is updated daily. Document structures include structured statistical tables and business description text. Core fields include container throughput (unit: TEU), total cargo handling volume (unit: tons), berth operation duration (unit: hours), and route operation frequency (unit: trips/week). Some detailed reports also include special fields such as single port area operation data and cross-border route proportion.
What constraints these characteristics impose on HTTP interfaces and external systems
Multi-cycle data requirements require interfaces to support pulling data across different time granularities including daily, monthly, quarterly and yearly. They must also support scenarios for batch pulling historical data. High-frequency demand for real-time operation data requires interfaces to support short-interval polling or Webhook push configuration. Consistent unit requirements for structured fields require clear specification of data units in interface parameters, to avoid cross-data-source conversion errors. Differentiated demand for special fields requires interfaces to support custom parameters for filtering specific port areas or route data. They must also be compatible with field mapping rules for different reports.
How to set configurations
| Configuration Item | Recommended Value | Basis for This Setting |
|---|---|---|
DATA_SOURCE_TYPE | Select "External API Data Source" | Shipping port financial report data mostly comes from official public APIs or customized statistical interfaces, not built-in knowledge bases |
API_REQUEST_INTERVAL | 300–600 seconds | Official port data update cycles are mostly monthly or quarterly. High-frequency polling will trigger interface rate limits |
API_RESPONSE_PARSER_MODE | Select "Structured Table Parsing" | Port financial report data takes structured tables as its core display format. This mode can accurately extract fields and units |
API_UNIT_AUTO_CONVERT | Enable | Different data sources may have unit differences (such as mixed use of TEU and standard containers). Automatic conversion can unify data formats |
MAX_BATCH_RECORDS | 50 records | Pulling too much data in a single batch will cause interface timeouts. 50 records adapts to the pagination limits of most port statistical interfaces |
API_AUTH_TYPE | Select "API_KEY Authentication" | Most official port statistical interfaces use API key authentication, without complex username and password processes |
The parameter values given 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 mistakes
- The interface call returns a
401 Unauthorizedstatus code, and the console prompts authentication failure. Cause: TheAPI_KEYparameter is not configured correctly, or an expired authentication key is used. Some port interfaces require binding a dedicated IP whitelist. - The optional parameter configuration items of the custom HTTP tool disappear, and new request parameters cannot be added. Cause: The "Advanced Parameter Configuration" switch is not enabled, or the tool configuration template was not resynced after deployment upgrade.
- The database query workflow returns empty results, and the logs show SQL syntax errors. Cause: The field naming rules for port financial report data are not adapted (such as mistyping
container_throughputastrans_vol), or no time range filtering condition is added, resulting in returned data being truncated due to excessive volume.
How to confirm the configuration is complete
- Initiate a single test request, check whether the fields and units of the returned data match the target port financial report data.
- View the interface call logs, confirm that the request interval conforms to the configured
API_REQUEST_INTERVALparameter, and there are no frequent rate limit error reports. - Verify the batch pull function, confirm that the number of returned data items does not exceed the limit of the configured
MAX_BATCH_RECORDS. - Test the authentication configuration, confirm that using an invalid key will trigger a
401 Unauthorizederror, and a valid key can return data normally.
