A PowerShell script to create a Dropbox Paper document from markdown, impersonating a Dropbox Business/Education/Enterprise Team Member.

DropboxAPI-CreatePaperDoc.ps1

param(
    [Parameter(Mandatory=$true)][String]$markdownFilePath,
    [String]$parentFolderID
)

$token = 'Bearer xxxyourapptokenherexxx'

#You'll need to use the Dropbox Business API to get the Team Member's ID.
$teamMemberID = "xxxxxx"

$authHeader = 'Authorization: '+$token

#This is Dropbox's way of granting your Team Member File Access app permission to run as a given user with user API endpoints.
$impersonationHeader = 'Dropbox-API-Select-User: '+$teamMemberID

#We have to escape quotation marks in HTTP headers when using curl.exe instead of Invoke-RestMethod
if($parentFolderID){
    $argsHeader = 'Dropbox-API-Arg: {\"import_format\": \"markdown\"}, \"parent_folder_id\": "'+$parentFolderID+'"'
}
else{
    $argsHeader = 'Dropbox-API-Arg: {\"import_format\": \"markdown\"}'
}

$result = &C:\path\to\curl.exe -X POST https://api.dropboxapi.com/2/paper/docs/create `
    --header $authHeader `
    --header $impersonationHeader `
    --header $argsHeader `
    --header 'Content-Type: application/octet-stream' `
    --data-binary $dataHeader | ConvertFrom-Json

return $result

I wrote this script in an attempt to use the Dropbox Paper API to automatically generate rapid response checklists/documents for phishing attacks, compromised accounts, and other security incidents. You can easily generate the markdown ".md" file by writing a template document in Dropbox Paper, downloading it in markdown format from the web interface, then adding placeholders/variables within the resulting document. Next, tell your script to swap out the placeholders with real data, then upload the new .md file using this PowerShell script.

You can use this other script to grab a Dropbox user's team member ID by passing it the user's email address.
