Sending Email from PowerShell using SendGrid (in Azure)

Send-SendGridMessage.ps1

$Username ="azure_*********@azure.com"
$Password = ConvertTo-SecureString "********" -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential $Username, $Password
$SMTPServer = "smtp.sendgrid.net"
$EmailFrom = "admin@acme.com"
$EmailTo = "user@acme.com"
$Subject = "SendGrid test"
$Body = "SendGrid testing successful"

Send-MailMessage -smtpServer $SMTPServer -Credential $credential -Usessl -Port 587 -from $EmailFrom -to $EmailTo -subject $Subject -Body $Body

Using API Keys with PowerShell, for sending attachments is the tricky part. SendGrid documentation too does have much on this. Can any one help here.

You can store the API Keys in KeyVault and retrieve the same from it.

$SENDGRID_API_KEY = (Get-AzKeyVaultSecret -VaultName $VaultName -Name $ApiKeyName).SecretValueText
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Authorization", "Bearer " + $SENDGRID_API_KEY)
$headers.Add("Content-Type", "application/json")

create a body json which has mail body content which has from and destination mail address details, subject and bodyContent of Mail
finally, call the below method.

$response = Invoke-RestMethod -Uri https://api.sendgrid.com/v3/mail/send -Method Post -Headers $headers -Body $bodyJson

The operation has timed out.
