FlutterFlow and Mailgun API integration: Step-by-Step Guide 2024

Step-by-Step Guide on Integrating FlutterFlow with Mailgun API

Integrating FlutterFlow with Mailgun allows you to send automated emails directly from your Flutter app. This guide will walk you through the process of setting up your account, creating API credentials, and configuring your FlutterFlow app to send emails through Mailgun.

Step 1: Set Up Your Mailgun Account

• Sign Up or Log In:

• Navigate to Mailgun's website.

• If you don't have an account, click on "Sign Up" and fill out the necessary information.

• If you have an account, simply log in.

• Verify Your Account:

• Follow the email verification process that Mailgun requires during the sign-up.

• Provide any additional information that might be required for your account set-up.

• Choose a Domain:
• You will need a domain to send emails. Either use a domain you own or use one of Mailgun's sandbox domains for testing purposes.

Step 2: Configure Domain Settings in Mailgun

• Access Domain Settings:

• Once logged in, go to the "Domains" tab on the Mailgun dashboard.

• Add or Select a Domain:

• If you’re using your own domain, add it by clicking "Add Domain."

• If using the sandbox domain provided by Mailgun, ensure it is configured and ready for use.

• DNS Setup (for Custom Domains):
• Follow the DNS setup instructions provided by Mailgun. This usually involves adding TXT, MX, and CNAME records to your domain registrar.
• Verify the DNS settings once configured.

Step 3: Obtain Mailgun API Credentials

• Navigate to API Keys:

• Go to “API Keys” under the “Security” section on the Mailgun dashboard.

• Copy the API Key:

• Note down your private API key. This will be used to authenticate your requests from FlutterFlow.

Step 4: Set Up FlutterFlow

• Open Your Project:

• Navigate to FlutterFlow and open the project where you wish to integrate Mailgun.

• Go to Settings:

• On the left menu, select "Settings" and then "API Configurations".

• Add Mailgun API Details:
• Add a new API configuration for Mailgun:
  • API Name: Mailgun
  • Base URL: https://api.mailgun.net/v3/YOUR_DOMAIN_NAME/messages (replace YOUR_DOMAIN_NAME with your actual Mailgun domain).
  • Headers: To authenticate, you need to add the following header:
  • Authorization: Use basic authentication. Convert the string api:YOUR_API_KEY to Base64 and prepend it with "Basic ". Example: Basic BASE64_ENCODED_STRING.

Step 5: Design Email-Sending Workflow in FlutterFlow

• Create or Access a Workflow:

• Go to the "Actions & Workflows" section in FlutterFlow.

• Configure API Call Action:

• Add an "API Call" action and select the Mailgun API configuration you just created.

• Set the method to "POST".

• Add API Call Parameters:
• Include required fields in your API call (use FlutterFlow's JSON format for body data):
  • from: Set the sender's email (e.g., "from": "[email protected]").
  • to: Set the recipient's email (e.g., "to": "[email protected]").
  • subject: Define the subject of the email.
  • text: Set the body text of the email. You can use variables from your app context.
  • html: (Optional) Provide an HTML version of the email content.

Step 6: Test Your Integration

• Deploy Your App:

• Run your app in test mode to check if all configurations have been set correctly.

• Trigger the Email Send:

• Perform the action in your app that should trigger the email sending (e.g., submitting a form).

• Check Email Delivery:
• Confirm that the email is delivered. You can check this in Mailgun's logs or by confirming with the recipient.

Step 7: Troubleshoot and Iterate

• Check for Errors:
• If emails are not sending, review the API call logs in FlutterFlow and Mailgun.
• Verify if the API key and domain configurations are correct, check the encoded API key, and ensure you're using the correct email addresses.

By following these steps, you should be able to successfully integrate FlutterFlow with the Mailgun API, allowing your Flutter application to send emails. Adjust the details as needed for your specific use case, such as customizing the email content or using dynamic data from your app.
