Upload a small file in one request
Upload a file in one multipart/form-data request.
Request bodies over 4.5 MB are rejected at the platform edge before they reach this route. For larger files, create an upload URL and PUT the bytes to it instead; the SDK’s files.upload() does that for files of any size. The Upload files guide walks through both flows.
At least one of job_execution_id and instrument_id is required, except in a job script, whose uploads default to the running job’s execution. Pass a job_execution_id for an artifact of a job execution, which also records provenance linking the file to that execution, and pass an instrument_id for data captured off-platform by an instrument the Sync app cannot reach, which attaches the file to that instrument so instrument triggers and parsers pick it up.
Requires an API key with the write scope.
