What this category's data looks like
Data sources for this category include real estate registration information systems, cadastral survey databases, housing transaction online signing systems, tax systems, and electronic certificate repositories. Daily processed documents include registration applications, ownership certificates, surveying and mapping results, tax payment vouchers, real estate ownership certificates, and registers. Data is updated once daily. Fields include real estate location, right holder information, right type, registration number, and more. Area-related fields use square meters as their unit. Certificate numbers use a fixed-length string format.
What constraints these characteristics impose on HTTP interfaces and external systems
Multiple data sources require interfaces to adapt to authentication rules and parameter formats of different external systems. Docking permissions must be configured separately. The daily update frequency requires interfaces to support scheduled pulling or trigger-based synchronization. This avoids exceeding system limits from frequent requests. Complex document structures require interfaces to handle both structured fields and unstructured files. Request bodies must be compatible with different data types. Errors in core business data have serious consequences. Interfaces must add verification and failure retry mechanisms to ensure the accuracy and integrity of data transmission.
How to set up the configuration
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {interface token assigned by external system} | Complies with OAuth2 authentication standards used by most external systems, ensuring legitimate interface access permissions |
variables | Bind business variables such as real estate location and registration application number | Adapts to parameter transfer requirements of different registration businesses, avoids hardcoding fixed parameters |
responseData | Extract core fields such as ownership status, register number, and right holder information | Filters invalid data, improves processing efficiency of internal office systems |
| Request timeout | 600 seconds | Real estate verification requires queries across multiple external systems, which takes a long time. Prevents request interruption from early timeout |
| Retry count | 3 times | Addresses temporary network fluctuations or temporary unavailability of external systems, improves interface call success rate |
| Data verification rules | Match registration application numbers with fields returned by external systems | Ensures consistency between incoming and returned data, prevents invalid data from entering the workflow |
Three common mistakes
- The
responseDatafield returned by the interface is empty. The symptom is that downstream systems cannot obtain core business data. The cause is that the extraction rule forresponseDatais not configured correctly, and only the original unfiltered response body is returned. - The interface call returns a 401 Unauthorized error. The symptom is authentication failure. The cause is an incorrect
Authorizationtoken format, or failure to bind access permissions for the corresponding external system. - Interface request parameters do not match. The symptom is that the external system returns a parameter error. The cause is that the
variablesbinding of business parameters is not configured correctly, resulting in failure to pass necessary registration business identifiers.
How to confirm the configuration is complete
- Call the test interface, check whether
Authorizationauthentication passes, and return a 200 status code. - Check whether the fields extracted by
responseDatainclude core business data, such as real estate ownership certificate number or register number. - Simulate cross-system requests, verify that business parameters bound by
variablesare correctly passed to the external system. - After configuring the retry mechanism, simulate temporary network interruption, check whether the retry process is automatically triggered.
