Uploads supporting documents of your organization, for example documents required for an outgoing transfer.
Send the files as multipart/form-data, one files part per file.Limits:
up to 10 files per request;
each file smaller than 6 MB, all files together smaller than 12 MB;
formats: .pdf, .jpg, .jpeg, .png;
file name up to 64 characters, containing only letters, digits, spaces and № $ & . , ! ( ) @ + _ ; -.
The response contains the stored file names; use them to download the documents or to attach them to an
outgoing transfer. A stored name is the original name with a prefix, and it must also fit into 64 characters
when attached to a transfer, so keep original names short. Every upload creates new files, even if a file with
the same name was uploaded before.
