Online Troubleshooting and Retrospective Analysis for Information Feed Ad Creative Testing: HTTP Interfaces and External Systems

The business data for information feed ad creative testing mainly comes from advertising platforms, material libraries, user interaction data, and

What the data for this use case looks like

The business data for information feed ad creative testing mainly comes from advertising platforms, material libraries, user interaction data, and conversion data. Update frequencies are mostly daily or weekly. Daily supporting documents include creative scripts, material test sheets, delivery data reports, and iteration checklists. Core fields include creative combinations (images/videos/copy), test batches, click-through rates, conversion costs, and violation flags. Core work for this use case revolves around creative variable design, material fatigue judgment, and test conclusion summarization. Both data and documents support effect verification and rapid iteration of creative combinations.

What constraints these characteristics impose on HTTP interfaces and external systems

The business characteristics of information feed ad creative testing impose multiple constraints on the HTTP interfaces and external systems link. Multi-source data docking requirements require interfaces to adapt to return formats of external systems such as advertising platforms and material libraries. Parameter passing must accurately match the field rules of different data sources. Daily or weekly update frequencies require interface synchronization to match the business rhythm. This prevents overly frequent requests from triggering rate limits, or too slow synchronization from causing test data lag. Creative testing document field requirements require interfaces to pass standardized creative variable parameters. This ensures consistency between test configurations and document content. Rapid iteration business requirements require interfaces to support interrupting model generation. Interfaces must also be compatible with access configurations for external large model APIs.

How to configure settings

Configuration ItemRecommended SettingRationale
AuthorizationA key string prefixed with BearerComplies with FastGPT API identity verification specifications, ensuring valid interface call permissions
variablesPass image IDs, copy content, test batch IDs for creative combinationsMatches fields in creative scripts and material test sheets, passing standardized test parameters
responseDataReturn only click-through rate, conversion cost, and violation flag fieldsFilters redundant data, adapts to field requirements of delivery data reports, reduces data transmission volume
Interface timeout period600 secondsMatches the daily data synchronization rhythm of creative testing, preventing valid test requests from being interrupted by short timeouts
Retry mechanismRetry 2 times after failure, with a 30-second intervalAddresses temporary fluctuations in advertising platform interfaces, reducing the risk of test interruptions
Interrupt generation switchEnabledSupports rapid switching of test variables, adapting to rapid adjustment needs for creative iteration

Three common configuration mistakes

  • Phenomenon: When sending test requests consecutively, subsequent requests cannot interrupt the previous model generation process, and the returned results still contain content from the previous request. Cause: The FastGPT interrupt generation configuration is not enabled, or the correct session identification parameter is not included in the request.
  • Phenomenon: The responseData field returned by the interface is empty, and delivery effect data cannot be obtained. Cause: The responseData parameter is not configured correctly, and the required core business fields are not specified, causing the interface to filter all returned content.
  • Phenomenon: Calling an external large model API returns an identity verification failure with a status code of 401. Cause: The Authorization parameter is not configured correctly, or the external large model access switch is not enabled in FastGPT v4.17.0.

How to confirm the configuration is correct

  • Send a test request carrying the variables parameter, check whether the returned results contain the passed creative combination fields, confirming that parameter passing is correct.
  • View the interface response log, confirm that the Authorization parameter verification passes, and there are no 401-level identity errors, ensuring normal interface permissions.
  • Send two consecutive test requests, verify that the subsequent request can trigger the interruption of the previous generation process, confirming that the interrupt configuration is effective.
  • After connecting to an external large model API, call the interface to confirm that the returned results conform to the response format of the corresponding model, verifying that the external access configuration is correct.
