What the data for this category looks like
Shipping port marketing content data originates from official port scheduling systems, shipper and freight forwarder reconciliation ledgers, and route promotional material libraries. Data update cycles cover real-time route adjustments, daily cargo volume announcements, and scheduled promotional material releases. The data structure includes structured fields such as route freight rates and port codes (compliant with UN/LOCODE standards), plus unstructured materials like high-definition posters and promotional videos. Fields include PORT_CODE, ROUTE_NAME, QUOTED_PRICE (unit: USD per TEU), UPDATE_TIMESTAMP, and some marketing assets have a unique identifier MATERIAL_ID.
What constraints these characteristics impose on HTTP interfaces and external systems
Structured data must strictly match standard field formats such as UN/LOCODE. Interfaces must configure parameter validation rules to block requests with invalid formats. Real-time updated marketing data requires interfaces to support scheduled pulling or webhook pushing to meet high-frequency data synchronization needs. Mixed-format material data requires interfaces to support both multipart/form-data and JSON transmission formats, and support large file uploads. Bulk cargo listing data processing may generate long-running requests. These requests must support execution durations over 1200 seconds to avoid forced timeout interruptions. Internal system connections require strict authentication to prevent sensitive marketing data leaks.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Shipping port marketing materials often include high-definition posters and promotional videos, resulting in large individual file sizes |
API_REQUEST_TIMEOUT | 1800 seconds | Bulk cargo listing data processing or long-running workflow execution may exceed 1200 seconds, so this setting must accommodate long-running scenarios |
AUTH_TYPE | API_KEY + IP_WHITELIST | Strict authentication is required for connections to internal port systems to prevent unauthorized access to sensitive marketing data |
PARSE_MULTIPART_FILE | Enabled | Support for passing user-uploaded images, PDF marketing materials via multipart/form-data format is required |
WEBHOOK_RETRY_COUNT | 5 times | Port system pushes of marketing data may fail due to network fluctuations, so a reasonable number of retries must be configured |
REQUEST_BODY_ENCODING | UTF-8 | Port data includes Chinese, English, and special port code characters, so a unified encoding format is required |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material types, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Symptom: The API returns a
413 Request Entity Too Largestatus code. Cause: TheUPLOAD_FILE_MAX_SIZEconfiguration was not adjusted, and large marketing materials cannot be uploaded because they exceed the default limit. - Symptom: Workflow execution times out, and the interface displays
Task execution timed out. Cause: TheAPI_REQUEST_TIMEOUTconfiguration was not increased, and bulk cargo listing data processing exceeds the default timeout threshold. - Symptom: The interface receives empty fields when passing images. Cause: The
PARSE_MULTIPART_FILEconfiguration was not enabled, and files were not passed in multipart/form-data format, so relative links cannot be parsed correctly.
How to verify correct configuration
- Upload a single marketing material file not exceeding 2000 MB, and check that the API returns a 200 status code and the file is parsed successfully.
- Initiate an API call for bulk cargo listing data, wait more than 1200 seconds, and check that the workflow completes normally without timeout errors.
- Configure an IP whitelist, then send a call from an unauthorized IP. Check that a
403 Forbiddenstatus code is returned, and calls from authorized IPs work normally. - Upload an image file and submit it in multipart/form-data format, and check that the interface receives non-empty file fields that can be parsed correctly.
