Unable to get past the 400 Error - api

Question

Code to create a new user:
function New-DropBoxUser {
[CmdletBinding()]
Param(
[Parameter(Mandatory=$true, ValueFromPipeline=$true, Position=0)]
[string]$FullName
)
# Split name into username #
$FirstName, $LastName = $FullName.split(' ')
$UserName = ($FirstName[0]+$LastName).toLower()
$email = "$UserName#mycomp.com"
$Body = #{
"new_members" = #(#{
"member_email" = $email;
"member_given_name" = $FirstName;
"member_surname" = $LastName;
"send_welcome_email" = "true";
"role" = #{
".tag" = "member_only"
}
})
}
Write-Host ''
Write-Host 'Creating DropBox User...' -ForegroundColor 'Yellow' -BackgroundColor 'Black'
$AuthToken = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
$token = "Bearer $AuthToken"
$response = Invoke-RestMethod `
-Method Post `
-Uri "https://api.dropboxapi.com/2/team/members/add" `
-Headers #{ Authorization = $token } `
-ContentType "application/json; charset=utf-8" `
-Body (ConvertTo-Json $Body)
}
Output:
Invoke-RestMethod : The remote server returned an error: (400) Bad Request.
Anyone, please tell me the fix. I tried the Endpoint "team/members/list" to fetch user list using the same $token and it works.
I am totally new to Dropbox API so my code is borrowed from Google, while being good with PowerShell I tried to patch up using many different codes but none worked.

Answer 1

When all else fails, RTFM, whose parameters say:
{
"new_members": [
{
"member_email": "tom.s#company.com",
"member_given_name": "Tom",
"member_surname": "Silverstone",
"member_external_id": "company_id:342432",
"send_welcome_email": true,
"role": "member_only"
}
],
"force_async": false
}
Try removing .tag from the role definition and replace "true" with $true
$Body = #{
"new_members" = #(#{
"member_email" = $email
"member_given_name" = $FirstName
"member_surname" = $LastName
"send_welcome_email" = $true
"role" = "member_only"
})
}
