What the documents look like
Letter-of-credit document examination and presentation turns on documentary consistency, because the bank's payment conditions are served by the documents themselves. The comparison differs from export tax rebate filing, which turns on tax matching. The main data sources are the issuing bank's advice, UCP600 clauses, the freight forwarder's bill of lading, and the bank's presentation records. The documents handled each time are the letter of credit, commercial invoice, bill of lading, insurance policy, and draft. These materials update once per transaction, and the examination outcome bears on refusal of payment, deducted charges, and delayed collection of foreign exchange.
Operating reports and exception reviews at the HTTP integrations step need to line up the examination status of each transaction, the presentation record, and the values returned by the external system. The check is whether the same transaction is consistent between internal records and the external interface response. Updates occur once per transaction; this page does not describe batch synchronization, full synchronization, real-time behavior, or transaction-triggered mechanisms.
A hypothetical paper exercise sample is used throughout this page. On 10 March 2025 a foreign-trade documentation clerk handles a sight letter-of-credit presentation for a consignment of export goods, where the credit requires the bill-of-lading date to be no later than 8 March. The material text is: "Bill of lading issue date 7 March 2025; commercial invoice amount USD 50,000; insurance policy insured amount USD 55,000." The draft sentence to be assessed is: "The presentation documents for this transaction are complete and the bill-of-lading date meets the letter-of-credit requirement." Assessing that sentence requires comparing the bill-of-lading date against the credit clause. The ratio relationship between the insured amount and the invoice amount is not stated in the source text and remains unsupported.
Constraints at the HTTP integrations step
The HTTP module sends an HTTP request to the corresponding address, and its practical operation resembles tools such as Postman and ApiFox. Params are path request parameters and are used mostly with GET requests. Body is the request body and is used mostly with POST and PUT requests. Headers carry special information. Custom variables can receive the output of preceding nodes as variables. All three data types can reference variables through {{}}, and the URL can also reference variables through {{}}. Variables come from global variables, system variables, and preceding node outputs.
System variables include appId, chatId, responseChatItemId, variables, cTime, and histories. chatId and responseChatItemId do not exist in test mode. Return values are obtained by configuring keys and extracting interface response values with JSON path syntax; output formatting mainly converts JSON into a string. The chat interface uses APIKey authentication. When calling chat/completions, passing body.appId in the request body is recommended, and Authorization: Bearer <apiKey>-<appId> is also supported. Passed fields such as model and temperature have no effect, because these are determined by the orchestration. When detail=true, intermediate values are returned and the complete result is stored in responseData. The interactive returned to an external caller is a display configuration containing only type and params; internal runtime fields such as entryNodeIds, memoryEdges, nodeOutputs, and nodeResponseId are not returned. Plugin calls need no chatId and no messages, take input through variables, and obtain output from the element with moduleType=pluginOutput.
Retrieval and relevance scores do not perform authorization or entity isolation. Similarity is not a category, entity, or permission filter, and it does not exclude unrelated businesses or unauthorized records. Retrieval is not authorization. Forms collect values, while business verification, approval, database writes, and external synchronization require their stated downstream implementation. A pending request is not an approval, an offered option is not execution, and an unsigned termination is not a completed termination.
Configuration and implementation checks
| Configuration item | Hypothetical trial starting point for this page | Verification method |
|---|---|---|
| Request address and method | Address and method filled in per the external interface document; the address references a provided variable | Compare the address and method against the external interface document |
| Headers authentication | Authorization uses Bearer {{token}} | Confirm the credential is injected through secure configuration and is not written into public samples |
| Body structure | JSON written per the external interface contract, with variables referenced through {{}} | Compare the JSON structure against the external interface contract |
| Return value extraction | Keys configured per JSON path syntax to extract response values | Compare the extraction path against the response structure |
| Debug identity fields | chatId and responseChatItemId do not exist in test mode | Confirm that an empty debug value is not treated as a business failure |
| Variable references | Global variables, system variables, and preceding node outputs | Check each actually passed value item by item |
Three common errors
- Treating the absence of chatId in test mode as a lost session. The input is a test-mode request, the comparison is whether the chatId field exists, and the observable result is that the field does not exist in test mode, which the documentation describes.
- Treating the
interactivereturned by an interaction node as the complete runtime state. The input is a response containing an interaction node, the comparison is the returned fields against the documentation, and the observable result is thatinteractivecontains onlytypeandparamswhile internal fields are not returned. - Treating retrieval or form collection as authorized execution. The input is a variable value submitted through a form, the comparison is the business authorization state against the form-collection behavior, and the observable result is that the form only collects values while business verification and database writes require a downstream implementation.
How to verify the setup
- Enter the material text and the draft sentence from the hypothetical sample. Compare the bill-of-lading date of 7 March 2025 against the credit requirement of no later than 8 March. The result satisfies the condition when the date is on or before 8 March, so that part of the draft sentence is supported. This is an expected outcome, not a completed test.
- Enter the insurance policy insured amount of USD 55,000 and the invoice amount of USD 50,000 from the hypothetical sample. Compare whether the source text states a required insured ratio. The result satisfies the condition when the source text states that ratio; here the source text does not state it, so the point remains unsupported and further evidence is required.
- Enter one HTTP request. Compare the request method against the external interface document. The result satisfies the condition when the method matches and the request can be sent; when the method does not match, record the item as pending verification and do not infer a specific error cause.
Where a document field is not provided, it remains unknown. Where evidence is missing, it remains missing. This page does not claim that any test, deployment, approval, refund, or other business action has occurred.
