}
Start an upload by POSTing the filename and size to /documents/init_upload. To actually perform the upload it is then necessary to transmit the file to the provided upload_url, with any additional_fields as needed.

​
Performing the actual upload

A typical upload involves POSTing a sample up to 20GB in size to a provided HTTPS URL. The Content-Type should be multipart/form-data and the additional_fields should be included in the POST body. The workflow using httpie or Python requests is: 
# Start the upload
# Start the upload
http --auth $ONE_CODEX_API_KEY: POST \
https://app.onecodex.com/api/v1/documents/init_upload \
filename=report.pdf size:=31337
