FlutterFlow and AWS SES integration: Step-by-Step Guide 2024

Step-by-Step Guide on Integrating FlutterFlow with AWS SES

Integrating FlutterFlow with AWS Simple Email Service (SES) allows you to send emails directly from your Flutter applications. This guide provides detailed steps to set up this integration effectively.

Step 1: Set Up AWS SES

• Sign into AWS Console:

• Open your browser and navigate to the AWS Management Console at AWS Console.

• Log in with your credentials.

• Navigate to SES Service:

• Once logged in, search for "SES" in the search bar.

• Click on "Simple Email Service" from the dropdown list.

• Verify Email Address:

• In the SES dashboard, click on "Email Addresses" under the "Identity Management" section.

• Click on "Verify a New Email Address."

• Enter the email address you want to verify and click "Verify This Email Address."

• Check the inbox of the email address you entered, and click on the verification link in the email from AWS.

• Move to Production (Optional):

• By default, your account is in SES sandbox mode, meaning you can only send emails to verified addresses.

• To increase sending limits and send emails to non-verified addresses, request to move to Production. This may involve additional steps, such as providing use case details to AWS.

Step 2: Configure AWS IAM

• Create an IAM User for SES:

• In the AWS Management Console, navigate to "IAM" (Identity and Access Management).

• Add a New User:

• Click on "Users" from the sidebar, then click "Add User."

• Enter a username (e.g., FlutterSESUser) and select "Programmatic access."

• Attach Policies:

• Click "Next: Permissions."

• Choose "Attach existing policies directly."

• Search for and select "AmazonSESFullAccess" to allow full access to SES.

• Click "Next: Tags," and then "Next: Review."

• Create User and Note Down Credentials:

• After reviewing, click "Create User."

• Download the .csv file with your Access Key ID and Secret Access Key. Store these in a secure location.

Step 3: Set Up FlutterFlow

• Open FlutterFlow:

• Visit FlutterFlow and log in to your account.

• Open the project you want to integrate with AWS SES.

• Navigate to Backend Services:

• In your project, navigate to the "Backend" sections or the equivalent place where services can be set up.

Step 4: Implement AWS SES in FlutterFlow

• Setup Custom Functions (Optional):

• If you’re using custom functions, in FlutterFlow, navigate to "Functions" or "Custom Actions."

• Create a new function to handle email sending.

• Script for Sending Emails:

• Use the AWS SES SDK to send emails. This would typically require setting up an HTTP function or a cloud function to interact with the AWS API.

• Integrate AWS SDK (Server-Side):

• This part typically requires a server-side implementation with Node.js or Python.

• For Node.js:

  • Install AWS SDK: Run npm install aws-sdk in your server environment.

  • Script Example:
    ```javascript
    const AWS = require('aws-sdk');
    AWS.config.update({region: 'REGION'}); // Replace 'REGION' with your SES region

    const ses = new AWS.SES({apiVersion: '2010-12-01'});

    const sendEmail = (to, subject, body) => {
    const params = {
    Destination: { ToAddresses: [to] },
    Message: {
    Body: { Text: { Data: body } },
    Subject: { Data: subject }
    },
    Source: 'your_verified_email@example.com'
    };

    ses.sendEmail(params).promise().then(
    data => console.log(data.MessageId)
    ).catch(
    err => console.error(err, err.stack)
    );
    };
    ```

• For Python:

  • Install Boto3: Run pip install boto3 in your server environment.

  • Script Example:
    ```python
    import boto3

    client = boto3.client('ses', region_name='REGION') # Replace 'REGION' with your SES region

    def send_email(to, subject, body):
    response = client.send_email(
    Source='your_verified_email@example.com',
    Destination={'ToAddresses': [to]},
    Message={
    'Subject': {'Data': subject},
    'Body': {'Text': {'Data': body}}
    }
    )
    print(response['MessageId'])
    ```

• Invoke From FlutterFlow:

• Use networking librariess like http in your Flutter project to call your server-side function or webhook.

• Example Flutter HTTP POST request:

\`\`\`dart
import 'package:http/http.dart' as http;
import 'dart:convert';

Future<void> sendEmail(String to, String subject, String body) async {
  final url = 'YOUR_SERVER_ENDPOINT'; // Replace with your server endpoint
  final headers = {"Content-type": "application/json"};
  final json = jsonEncode({'to': to, 'subject': subject, 'body': body});

  final response = await http.post(url, headers: headers, body: json);

  if (response.statusCode == 200) {
    print(response.body);
  } else {
    print('Failed to send email: ${response.statusCode}');
  }
}
\`\`\`

Step 5: Test the Integration

• Send Test Emails:
• Use your Flutter app to trigger email sending functionality.
• Monitor the SES console to see if emails are being sent.
• Check the recipient’s inbox (and spam/junk folder) to ensure delivery.

Conclusion

Integrating FlutterFlow with AWS SES can significantly enhance your app’s functionality by enabling email sending capabilities. This guide provides a comprehensive overview of the steps involved in setting up and implementing this integration. Remember, testing is crucial in confirming every part of the integration works smoothly.
