Using Java SDK and Microsoft Graph API V6 with Kotlin for Email Dispatch

Using Kotlin and Java SDK to Implement Email Dispatch via Microsoft Graph API V6

Kotlin Integrating with the Java SDK

// Build.gradle.kts dependencies for Microsoft Graph API, Azure Identity, and Jakarta Annotation
implementation("jakarta.annotation:jakarta.annotation-api:2.1.1")
implementation("com.azure:azure-identity:1.11.4")
implementation("com.microsoft.graph:microsoft-graph:6.4.0")

// Kotlin Main Function: Setup and Send Email
fun main() {
    val clientId = "YOUR_CLIENT_ID"
    val tenantId = "YOUR_TENANT_ID"
    val clientSecret = "YOUR_CLIENT_SECRET"
    val scopes = arrayOf("https://graph.microsoft.com/.default")
    val credential = ClientSecretCredentialBuilder()
        .clientId(clientId)
        .tenantId(tenantId)
        .clientSecret(clientSecret)
        .build()
    val graphClient = GraphServiceClient.builder().authenticationProvider(credential).buildClient()
    // Prepare the message
    val message = Message()
        .subject("Meet for lunch?")
        .body(ItemBody().contentType(BodyType.HTML).content("The new cafeteria is open."))
        .toRecipients(listOf(Recipient().emailAddress(EmailAddress().address("frannis@contoso.com"))))
    // Send the email
    graphClient.users("sender365@contoso.com").sendMail(UserSendMailParameterSet(message, false)).buildRequest().post()
}

Email Composition and Authentication Process Using Microsoft Graph API V6

Error Management and Parsing Responses in Kotlin

// Error Handling for Microsoft Graph API
try {
    // Attempt to send an email
} catch (e: ApiException) {
    println("Error sending email: ${e.message}")
    // Parse and log detailed error information
    val error = ODataError.createFromDiscriminatorValue(e.errorContent)
    println("OData Error: ${error.message}")
}

// Handling the /me endpoint error specifically
if (graphClient.me().requestUrl.contains("/me")) {
    println("The /me endpoint requires delegated authentication flow.")
}
// Example of alternative approach if /me endpoint is mistakenly used
try {
    graphClient.users("{user-id}").sendMail(sendMailPostRequestBody, null).buildRequest().post()
} catch (e: Exception) {
    println("Correctly use user-specific endpoint instead of /me for application permissions")
}

Important Questions about Microsoft Graph API Version 6 for Email Automation

1. Microsoft Graph API V6: What is it?
2. The most recent iteration of the unified API endpoint for gaining access to Microsoft Cloud services, such as calendar, contacts, email, and more, is called Microsoft Graph API V6, and it comes with improved capabilities and security.
3. How can I use the Microsoft Graph API to authenticate myself?
4. Microsoft Identity platform tokens, which are acquired using OAuth 2.0 authorization flows such client credentials or authorization code grants, are used for authentication with the Microsoft Graph API.
5. Is it possible to use the Graph API to send emails with attachments?
6. It is possible to send emails with attachments using the Graph API. You can include the file content in the request to build a message with attachments.
7. How should I respond to mistakes in emails I send?
8. Detailed error answers are provided via the Graph API. To interpret these answers and take the proper action in accordance with the error codes and warnings, developers need put error handling logic into place.
9. Is it feasible to email someone else on their behalf?
10. Yes, you can use the Graph API to send emails on behalf of another person by configuring the sender or from properties in the message object, provided you have the necessary permissions.

Using Microsoft Graph API V6 to Boost Email Automation: An Overview
