What the documents look like
For procurement in B2B marketplaces, this page examines FastGPT HTTP integrations. Compare the material received with the sources used in the answer. The examples are hypothetical.
Constraints at the HTTP integrations step
A procurement reader must distinguish statements in certification documents and a quotation from information an external service can supply. In the proposed text example, one document records raw-material production qualifications and the other lists specifications and pricing. These statements define a lookup need, not an existing qualification-checking API. Before using a FastGPT HTTP node, inspect the implemented interface contract, address, method, authentication and actual input values. Retain the original records returned by the business service.
Configuration and implementation checks
| Implementation check | Task-specific input | Acceptance evidence |
|---|---|---|
| Address and method | The lookup target requiring an external contract: A check of the production qualifications in the business certification documents against the raw material specifications in the inquiry and quotation sheet is required | Verify the connected service’s address and method; Business Certification Documents and Inquiry and Quotation Sheet is not an API merely because it is named. |
| Actual input values | A check of the production qualifications in the business certification documents against the raw material specifications in the inquiry and quotation sheet is required | Inspect origins and actual values in Params, Headers or Body against the contract. |
| Source meaning | The comparison required for Business Certification Documents and Inquiry and Quotation Sheet: A check of the registered address in the business certification documents against the shipping origin in the inquiry and quotation sheet is required | Distinguish business meanings before mapping variables; a difference is not automatically an error. |
| Test context and evidence gaps | Evidence still needed concerning Business Certification Documents: Historical supply records and performance reports for this supplier are currently missing | Check availability of test-context fields such as chatId separately from missing business evidence. |
| External response | Candidate data sources for this question: B2B Platform, National Enterprise Credit Information Publicity System, Payment Transaction Records and Logistics Tracking | Inspect what the actual response retrieved or processed; a lookup is not a write receipt. |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Request address and method | The request address and method follow the external contract. |
Params and Headers | Inspect parameters, headers and authentication separately. |
| Body | Where a JSON body is used, validate its structure against the external contract. |
Variable references | Variables can come from global, system or upstream outputs. |
Debug identity fields | Test mode lacks chatId and responseChatItemId. |
Three common errors
A registered address in City A and a shipping origin in City B describe different locations. They are not inherently contradictory supplier statements. If the proposed lookup concerns an address, specify which location is requested and retain the certification and quotation sources separately. When inspecting Params, Body or upstream variables, keep their business meanings distinct. A successful response still needs its field definitions checked to establish which location question it answers. If an absent test-mode chatId is interpreted as a failed supplier query, inspect the call mode and actual business conditions. That identity field is absent during testing and cannot replace the address response as query evidence.
How to verify the setup
Certification documents alone do not establish historical supply performance. Identify an authorized provider for those records and prepare the inputs required by its actual interface. Missing chatId or responseChatItemId in test mode is separate from an absent performance report; conversation variables cannot supply business evidence. After obtaining records, repeat the lookup and inspect both returned content and its receiving step. Supplier admission and order approval require their own business process.
