When "process" is configured on server side and **SIGNIUS Sealing Client** is restarted, it creates directory with three hardcoded subfolders "in", "out" and "err". When document sealing/signing is required, simply put (copy or move) file into "in" subfolder and a moment later the file will disappear and reappear already signed in the "out" subfolder. If however something unexpected happened that prevented document sealing/signing, it will appear in the "err" folder unsigned. Supports both local and network directories (UNC path format) ### REST API Details on the REST API communication are available at (links below): {% embed url="" %} {% embed url="" %}
