There are currently 3 different assessment APIs that allow you to programmatically retrieve assessment data that you own or that has been shared with you on the Worldly platform.The Bulk CSV API provides a CSV data stream that exactly matches what is available in the web portal for bulk download. The intent of the Bulk CSV API is not real-time interactions, it is for full data export/import use cases. Since this request can be 10’s or 100’s of megabytes in size, it is not useful for realtime interactions.The Performance CSV API provides a CSV data stream that exactly matches what is available in the web portal for performance csv download. This is intended for supporting the vast majority of analysis use cases for the FEM and is oriented around quantitative metrics.The Module Data API is intended for real-time use cases, such as adding a specific data attribute to a scorecard (ex: total score) or for probing specific attributes across many modules.
