REST API Documentation: Files

Concepts

The File API enables uploading and transforming data for subsequent visualization by the visualization dataset API. It is meant for use cases like reusing the same file across different visualizations, such as for faster interactive data cleaning. Multiple file formats may be uploaded.

The flow is roughly:

POST a file, with potential settings
POST data upload for the file, triggering a parsing attempt
Potentially iterate over sending PATCH calls for the file or POSTs for different data
Create a visualization that uses the uploaded file(s)
