What the data for this category looks like
Property management marketing content data primarily comes from internal property operation systems, owner service mini-program backends, and offline event registration records. Update frequency varies by scenario: Community event announcements are released 1 to 7 days in advance. Payment reminders update on a fixed monthly cycle. Merchant recruitment information adjusts in real time as tenancy status changes.
The document structure includes title, applicable building range, release time, attachment files, and liaison contact fields. The building range field uses the format "X Building Y Unit". Supported attachment file formats are PDF, JPG, and PNG. Single attachment size typically aligns with standard upper limits for property operations.
What constraints these characteristics impose on HTTP interfaces and external systems
The characteristics of property management marketing content data impose clear constraints on HTTP interfaces and external systems.
The "X Building Y Unit" format for building ranges requires interface configuration field validation rules to block request parameters with invalid formats. Attachment file format and size limits require the interface to enable whitelist validation and single-file size threshold configuration, to prevent unauthorized file uploads. Real-time updated merchant recruitment information requires the interface to support high-frequency calls, with reasonable request rate limits configured. Payment reminders and event notifications updated monthly require the interface to support data filtering by time range and owner group, to ensure returned content matches the corresponding service targets.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_ALLOW_EXT | ["pdf", "jpg", "png"] | Matches common attachment formats for property management marketing content such as posters and notifications |
UPLOAD_FILE_MAX_SIZE | 100 MB | Aligns with standard size limits for attachments such as property event posters and payment receipts |
REQUEST_RATE_LIMIT | 60 requests per minute | Adapts to high-frequency update call demands for merchant information and event notifications |
DATA_FILTER_FIELDS | ["building range", "owner group"] | Supports filtering returned marketing content by core property operation dimensions |
API_TIMEOUT | 30 seconds | Covers processing duration for large attachment parsing and multi-dimensional data splicing |
MAX_RECALL_RESULTS | Top 8 entries | Matches the upper limit of marketing content received by owners in a single instance, to avoid information overload |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Scenario: File upload is enabled in the frontend interface, but calling the chat interface to upload a file returns a
400 Bad Requesterror, and attachments cannot be submitted. Cause: TheUPLOAD_FILE_ALLOW_EXTwhitelist is not configured, or a file format not used for property management marketing content is uploaded. - Scenario: When pulling marketing content using the knowledge base API, returned results are not filtered by building range, and irrelevant cross-building notifications appear. Cause: Building range filtering in
DATA_FILTER_FIELDSis not enabled, or the passed filter parameter format does not meet the "X Building Y Unit" requirement. - Scenario: High-frequency calls to the merchant information interface return a
429 Too Many Requestserror, and requests are blocked. Cause:REQUEST_RATE_LIMITis not configured to adapt to the real-time update call frequency of property management, resulting in exceeding the interface current limit threshold.
How to confirm configurations are set correctly
- Send a POST request containing a commonly used PDF attachment for property management, check the returned response status code and error prompt to confirm that file format and size validation is active.
- Pass a building range parameter that conforms to the "X Building Y Unit" format, call the data pull interface, and check whether returned results only include marketing content for the corresponding building.
- Send consecutive call requests, check whether current limit interception is triggered, to confirm that the request frequency configuration meets business requirements.
- Send a request containing a large attachment, wait for the processing duration and check the response, to confirm that the interface timeout configuration adapts to actual processing needs.
