How can I integrate with my web system?

[leandrocombr]

Hello,

I installed Collabora Online and managed to make the Wopi API work with the parameters

https://host/wopi/files/:fileId

Size => 11,
IsAnonymousUser => false,
UserId => "uid-45447",
UserFriendlyName => "My Name",
UserCanReview => true,
UserCanWrite => true,
FileExtension => '.docx',
BaseFileName => 'Test.docx',
UserCanPresent => false,
SupportsUserInfo => true,
UserInfo => 'UserInfo',
HidePrintOption => false,
DisablePrint => false,
UserCanReview => true,
BreadcrumbBrandName => "Our Platform",
ClosePostMessage => true

I have some questions and where to find:

How do I save the content on my system (because every time I open the link it returns to the initial file)?
How to open WORD or HTML files?
How to open a template file?
Can I use

in a form on my system?
