HTTP Interfaces and External Systems for Residential Development Marketing Content

Residential development marketing content data primarily comes from sales management systems, housing authority pre-sale certificate disclosure

What the data for this category looks like

Residential development marketing content data primarily comes from sales management systems, housing authority pre-sale certificate disclosure platforms, project customer research databases, unit design documents, and surrounding facility disclosure information. It also includes mortgage product information provided by financial institutions, such as down payment ratios and interest rate ranges.

Update cadence is as follows: project basic information updates in real time with pre-sale certificate approval or unit adjustments; customer profile data updates monthly; marketing materials are replaced regularly per campaign events; mortgage product information adjusts in real time with market policies.

Document structure includes core fields: unique project identifier, floor area (unit: square meters), internal floor area (unit: square meters), pre-sale certificate number, customer budget range (unit: ten thousand yuan), marketing material external links, mortgage product parameters, and others. Single document content length varies based on project scale.

What constraints these characteristics impose on HTTP interfaces and external systems

Residential development marketing content involves compliant data disclosed by housing authorities and mortgage product information from financial institutions. External interfaces must be configured with identity authentication mechanisms to prevent unauthorized access to sensitive information.

Fields include standardized unit area, budget, and interest rate parameters. Interfaces must validate parameter formats to avoid parsing errors caused by non-standard units or formats.

Single documents have long content and many fields. Interfaces must support pagination retrieval and field restriction to avoid response overload that impacts call efficiency.

Customer data updates monthly and mortgage product information adjusts in real time with market policies. Interfaces must support pulling the latest version of data by project ID, with version number identifiers to distinguish updated content.

How to Set Configurations

Configuration ItemRecommended ValueRationale
external_api_timeout300 secondsResidential development marketing content includes bulk data such as pre-sale certificates and floor plans, which take a long time to pull via interfaces. 300 seconds covers complete data return
external_api_auth_modeAPI_KEY authenticationResidential development marketing data involves project compliant information and financial product parameters. Fixed key verification is required to check the caller's identity and prevent unauthorized access
response_field_whitelistproject name,floor area,internal floor area,pre-sale certificate number,customer budget,mortgage interest rateResidential development marketing content has many fields. Restricting the whitelist reduces invalid data transmission and improves interface response speed
param_unit_validateenabledArea, budget, and interest rate fields in residential development data must use square meters, ten thousand yuan, and percentage formats uniformly. Validation can avoid parameter format errors
api_versionv2Interfaces for residential development compliant data and financial products mostly use v2 version, which is compatible with the latest pre-sale certificate, filing information, and mortgage parameter fields

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on samples specific to the deployment before finalizing.

Three Common Misconfigurations

  • When a database connection plugin is used to pull residential development customer data, the interface prompts "Workflow verification failed, please check for missing or empty values, and whether connections are normal". The cause is that the db_connection_timeout parameter is not configured. The database connection times out before completing data pulling, triggering the verification logic interception.
  • Calling a published API returns 422 Unprocessable Entity. The cause is that the area parameter uses square feet instead of square meters, and param_unit_validate verification is not enabled, resulting in format mismatch.
  • The Human field in the conversation preview is null. The cause is that the user identifier field is not configured in response_field_whitelist, so the conversation context returned by the interface is not bound to valid user information.

How to Confirm Configurations Are Correct

  • Call the configured external interface, check whether the returned fields are included in response_field_whitelist, and confirm that the field formats meet the unit requirements of residential development data.
  • Test the database connection plugin to pull customer data, observe whether the workflow passes verification, and confirm that the db_connection_timeout parameter is configured appropriately.
  • Initiate a conversation request, check whether the Human field in the conversation preview has valid content, and confirm that the authentication and context binding configurations are correct.
  • View the interface logs, confirm that the response timeout time does not exceed the external_api_timeout configuration value, and confirm that the interface call link is normal.
