What the documents look like
Brand after-sales repair work turns on warranty responsibility and physical service points. Unlike platform after-sales on e-commerce channels, the work extends past refund handling into spare-part purchasing and supplier records. The main sources are the after-sales system, store orders, repair-point feedback, and the national three-guarantee catalogue. Warranty cards, repair work orders, inspection reports, and exchange approvals are everyday documents. Judging warranty scope, coordinating spare parts, and approving returns or exchanges consume the most time. When these materials enter an HTTP interface, the request body carries work-order numbers, part names, supplier details, and approval status, while return values are used to write back inventory or supplier records. Materials update per order and daily; this page does not derive batch synchronization or real-time triggering from that cadence.
For procurement and supplier records, the practical consequence is that a repair work order, a supplier quotation, and an approval field can sit in different states at the same moment. A request that carries a part number and quantity is a transport action. The approval state shown in the source material is a separate fact, and the HTTP step does not decide it.
Constraints at the HTTP integrations step
The HTTP module sends a request to a corresponding address, with behavior close to Postman and ApiFox. Params hold path request parameters and are used mostly with GET. Body holds the request body and is used mostly with POST/PUT. Headers carry special information. All three data locations can reference variables through {{}}, and the URL can also reference variables. Variables come from global variables, system variables, and upstream node outputs. System variables include appId, chatId, responseChatItemId, variables, cTime, and histories. The chatId and responseChatItemId values do not exist in test mode, so a missing value during debugging is not a business fault. Return values are extracted with JSON path syntax; when the output type is set to string, the value at the corresponding key is converted to a JSON string for downstream text processing.
When calling chat/completions, passing body.appId in the request body is recommended. An Authorization: Bearer <apiKey>-<appId> form is also supported for OpenAI SDK compatibility. The appId priority order is body.appId, then <apiKey>-<appId>, then the appId associated with the apikey. The model and temperature fields passed in are ineffective because the orchestration decides them. These mechanisms carry and parse data. They do not perform authorization judgment.
Hypothetical paper exercise sample: a brand after-sales center plans to submit a spare-part procurement handover request to an external inventory system through the HTTP module. The source text for comparison reads: "Repair work order WX-2024-0517, brand after-sales center, replacement part is a battery of a given model, quantity 2 pieces, supplier record page marked 'quotation valid until June 30, 2024', exchange approval column is 'pending review'." The draft sentence to be judged reads: "This procurement request has been approved and can be ordered directly at the quotation." That sentence writes a pending-review state as approved and treats the quotation validity date as a supply deadline. Both points exceed the source text.
Configuration and implementation checks
The table lists only officially described settings or implementation check items relevant to this page's sample. The values are starting points for this hypothetical exercise; the reason for each choice is stated and each is compared against a corresponding value. They are not defaults.
| Configuration item | Hypothetical starting point for this exercise | Check method and reason |
|---|---|---|
| Request address and method | The order interface provided by the external inventory system; method chosen per that interface's documentation | The address can reference variables; the method follows the interface documentation and is not preset |
| Headers authentication | Authorization injected through secure configuration | Verify the credential is not written into public samples; a proxy identity still needs target permissions |
| Body structure | Contains work-order number, part, quantity, supplier fields | Check the JSON structure and actual passed values item by item against the external interface contract |
| Variable reference | Work-order number and quantity come from upstream node outputs | Check actual passed values item by item and confirm they match the work order |
| Return value extraction | Extract the status field by JSON path | When output type is string, it is converted to a JSON string for downstream text processing |
| Authorization boundary | Approval status is used only as a display field write-back | A form collecting a value is not approval execution; writing and synchronization need downstream implementation |
Three common errors
- Treating "exchange approval column is pending review" in the material as approved and ordering on that basis. The input is the approval column in the source text; the comparison is between "pending review" and "approved", which are mutually exclusive values of the same field. Writing it as approved contradicts the source text.
- Treating "quotation valid until June 30, 2024" as a supply deadline or an ordering basis. The input is the quotation validity field; the comparison is between a validity date and a supply deadline. The source text does not state a supply deadline, so this can only be recorded as unsupported.
- Treating a similarity score or node status returned by the HTTP module as a basis for permission or entity isolation. The input is the score or status field in the return value; the comparison is against a business authorization conclusion. Retrieval and similarity do not perform authorization judgment, and authorization needs a separate system implementation.
How to verify the setup
- Input the hypothetical source text above and the draft sentence "This procurement request has been approved and can be ordered directly at the quotation." Compare whether the draft sentence matches the approval column and quotation validity field in the source text. The observable result is: the draft sentence contradicts the source text and is judged not to pass; if rewritten as "the approval status is pending review, and the quotation is valid until June 30, 2024", it matches the source text and is judged to pass.
- Input a Body declaration in which the work-order number and quantity reference upstream node outputs. Compare whether the actual passed values match work order WX-2024-0517 and quantity 2. The observable result is: if the passed values match, it passes; if the quantity is written as a fixed value or references the wrong variable, record the difference and do not infer the downstream write result.
- Input a return value extraction configuration and a segment of interface response example. Compare whether the extraction key corresponds to the response structure. The observable result is: if the key matches, the corresponding value is obtained; if the key does not exist, that item is empty and the gap is recorded. Do not claim the system necessarily reports an error or automatically fills the value.
The primary task here is judging whether proposed copy and request content match the supplied source wording and its limits. Identity certification, report analysis, and downstream write-back are separate tasks and are not tested by these checks.
