What data for this category looks like
This category of data typically originates from ERP systems, WMS warehouse management systems, barcode/RFID equipment, work order systems, storage location management modules, AGV transport systems and weighing equipment. Daily associated documents include receiving slips, putaway slips, material picking and return slips, warehouse transfer slips, inventory count sheets, lot ledgers, as well as first-in first-out and expiration date records. Common data fields include material codes, lot numbers, storage location codes, inventory quantities, expiration dates and real-time AGV positions. Units include pieces, kilograms, days and others. Data update frequencies fall into three categories: real-time (such as AGV positions and storage location changes), daily (such as inventory count snapshots) and monthly (such as full warehouse inventory summaries).
What constraints do these characteristics impose on HTTP interfaces and external systems
The multi-source data origins of this category require HTTP interfaces to support integration with various external systems, and compatibility with different authentication and data format standards. Core data centers on lots and storage locations. Interface requests must bind precise query parameters to avoid invalid requests. Requirements for different update frequencies mean interfaces must support both real-time push and scheduled pull invocation modes. The core goals of account-actual consistency and quality traceability require that interface-returned data must include complete identity and status fields, and must not omit key traceability information.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {wms_api_token} | External systems for warehousing, lot management and in-plant logistics (such as WMS) typically use Bearer token authentication, which complies with industry general interface specifications |
variables | Pass lot numbers, storage location codes, expiration date ranges | Core data of this category revolves around lots and storage locations, so dynamic binding of query parameters is required to accurately match target data |
responseData | Return material codes, inventory quantities, expiration dates, real-time AGV positions | Only retain core fields required for quality traceability to reduce data transmission load |
| Request timeout period | 600 seconds | This category includes bulk inventory data query scenarios, and 600 seconds covers most conventional bulk request durations |
| Number of items per single request | Top 100 items | Limit the amount of data returned per single request to avoid exceeding the carrying capacity of external interfaces |
Three Common Misconfigurations
- Interface calls return a 401 Unauthorized error: The
Authorizationparameter is not configured correctly, an expired external system token is used, or the correct authentication prefix is not included. - Query results are empty or only partial fields are returned: Core query conditions such as lot numbers and storage location codes are not passed in
variables, or required return fields are not configured inresponseData. - Bulk requests trigger timeouts: A reasonable request timeout period is not set, or the number of items returned per single request is not limited, resulting in exceeding the response time limit of the external interface.
How to Confirm Configuration is Complete
- Manually invoke the configured HTTP interface to check if the returned
responseDataincludes preset core fields such as material codes and lot numbers. - Pass a known valid lot number and storage location code to verify that the inventory data returned by the interface matches the ledger records in the WMS system.
- Simulate a bulk query scenario to confirm that the request completes a response within the preset 600 seconds, and the number of returned items does not exceed 100.
- Check the format of the
Authorizationparameter to confirm it complies with the authentication requirements of the connected external system.
