Upload an attachment

POST

/tasks/{task_gid}/attachments

Upload an attachment.

This method uploads an attachment to a task and returns the compact
record for the created attachment object. It is not possible to attach
files from third party services such as Dropbox, Box & Google Drive via
the API. You must download the file content first and then upload it as
any other attachment.

The 100MB size limit on attachments in Asana is enforced on this endpoint.

This endpoint expects a multipart/form-data encoded request containing
the full contents of the file to be uploaded.

Requests made should follow the HTTP/1.1 specification that line
terminators are of the form CRLF or \r\n outlined
here
in order for the server to reliably and properly handle the request.
