What the data looks like
Data for rural commercial bank marketing content originates primarily from internal customer group management systems, local government merchant filing databases, and customer information collected offline at bank branches. The data structure includes fields such as customer household registration township code, bound branch ID, marketing material templates, and product information for target customer groups. Units are 6-digit administrative division codes, integer branch IDs, character-type material content, and product quota measured in yuan. The data updates once per week. Materials for some temporary marketing campaigns are updated 24 hours before the campaign launches.
Constraints for HTTP interface and external system integration
The characteristics of rural commercial bank marketing content data create multiple constraints for HTTP interface and external system integration. First, the data includes 6-digit township administrative division codes and branch IDs. Interfaces must support parameter validation precise to the local area, to prevent cross-region calls for non-local branch marketing content. Second, the data updates once per week or via temporary triggers. Interfaces must adapt caching strategies for these cycles to reduce invalid requests. Additionally, most connected internal systems are deployed locally. Interfaces must support permission validation based on branch IDs, and be compatible with TLS verification for self-built CA certificates to meet internal security specifications. Finally, interface parameters must match the field naming rules of internal systems, to avoid data acquisition failures caused by mismatched fields.
How to configure settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
request_timeout | 30 seconds | Internal systems of rural commercial banks typically have slow response speeds. Short timeouts will cause normal requests to fail |
cache_ttl | 604800 seconds (7 days) | Marketing customer group data updates once per week. Cache expiration time matches the update cycle |
auth_type | api_key + ip_whitelist | Rural commercial bank internal systems have high data security requirements. Dual validation effectively prevents unauthorized access |
allowed_branch_ids | 6-digit administrative division code of the corresponding branch | Restrict calls to marketing content only for the local branch, in compliance with local management requirements |
request_max_size | 2048 characters | The length of a single marketing material typically does not exceed this limit, to avoid invalid large requests occupying bandwidth |
response_field_filter | ["customer_id", "town_code", "product_name"] | Only return core fields required for marketing, to reduce data transmission volume and parsing overhead |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- An interface call returns the error
tls: failed to verify certificate: x509: certificate signed by unknown authority. This occurs because the rural commercial bank’s internal system uses a self-built CA certificate, and no trusted CA list has been configured on the platform. - The workflow HTTP module returns empty values when receiving custom variables. This occurs because variables have not been mapped to the
bodyorqueryparameters of the interface request, and do not match the field names of the rural commercial bank’s customer group data. - The interface returns more marketing content entries than expected. This occurs because the
allowed_branch_idsparameter has not been configured, resulting in redundant cross-branch data being returned.
How to verify correct configuration
- Send a test request with the administrative division code of the target branch, and check if the returned marketing content only includes materials for that branch.
- View interface logs to confirm that the request carries the correct API key and IP whitelist, and that no certificate verification errors occur.
- Modify the cache expiration time to a short cycle, and verify that the interface returns the latest marketing content after the internal system updates its data.
- Pass custom customer group variables, and check if the interface correctly receives and matches the corresponding fields of the customer group data.
