Structure: categoryId [type: String] - The ID of the category to which the short link corresponds, or NULL if the short link does not correspond to a category. accountId [type: String] - The ID of the account to which the short link corresponds, or NULL if the short link does not correspond to a account. tenantId [type: String] - The ID of the tenant to which the short link corresponds, or NULL if the short link does not correspond to a tenant. Usually this is the tenant of the caller. fileSystemEntryId [type: String] - The ID of the file system entry to which the short link corresponds, or NULL if the short link does not correspond to a file system entry. timeToLive [type: String] - A timespan-formatted string representing the amount of time the short link should be valid. If not specified, the short link will never expire.
If a category ID is specified, any existing link with the same category/account/file combination will be updated, rather than a new link being created.
