Passing additional parameters for Vault

Hi dhtmlx,
I’m trying to add additional parameters just before upload or before add a file.
I use dhtmlxVault 3.0 Pro.
Thanks in advance.

Please, try to use the uploader object properties: https://docs.dhtmlx.com/vault/api__refs__uploader_props.html
Like:
https://docs.dhtmlx.com/vault/api__uploader__headerparams_config.html
or the
