See https://blog.neilsabol.site/post/onetimesecret-api-powershell-cli-basic-example-one-time-secret/ . This snippet uses Invoke-RestMethod and the OneTimeSecret API to generate a random password then output the password and secret link to retrieve it.

# Your OneTimeSecret Username and API key from https://onetimesecret.com/account#apikey-tab
$apiUsername = "username@example.com"
$apiPassword = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

# Invoke-RestMethod is a little "tempermental" with Basic Authentication - the "-Credential" parameter specifically
# See https://stackoverflow.com/questions/24672760/powershells-invoke-restmethod-equivalent-of-curl-u-basic-authentication - thanks Borek Bernard
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $apiUsername,$apiPassword)))

# Specify parameters for random password generation - in this case, a Time to Live in seconds (7 days)
$Body = @{
     ttl = 604800
}

# Call the OneTimeSecret API to generate a random password
$oneTimeSecret=Invoke-RestMethod -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)} -Method 'Post' -Uri "https://onetimesecret.com/api/v1/generate" -Body $body

# Print the generated secret and a URL you can share
write-host "$($oneTimeSecret.value)"
write-host "https://onetimesecret.com/secret/$($oneTimeSecret.secret_key)"

# Clear variables
$oneTimeSecret = ""
$apiPassword = ""
$base64AuthInfo = ""

I see, Neil, thank you for the explanation.
