Mailgun API

Discover more about the Mailgun API connector and how to use it on the Digibee Integration Platform.

Mailgun API integrates with Mailgun’s email delivery service, allowing you to send emails with custom recipients, subjects, and content, including attachments. It helps automate notifications, transactional emails, and marketing messages within your pipelines.

Usage examples

Sending an email

This connector allows you to send emails by specifying message components such as to, from, subject, HTML, and text parts. If you are using a free plan for testing purposes, you can only send emails to Authorized Recipients.

Required fields: The from, to, and subject fields must be included in the request body schema for the email to be sent successfully.

On the Digibee Integration Platform, you can send emails in two ways:

By passing the full body directly in the connector
By using Double Braces expressions

Passing the full body

}

Using Double Braces expressions

To send an email using Double Braces expressions, you need to:

Place a JSON Generator connector before the Mailgun API connector.
Use the following JSON payload:

{
    "from": "Mailgun Sandbox <[email protected]>",
    "to": "John Doe <[email protected]>",
    "subject": "Hello!",
    "text": "Welcome to Digibee"
}

3. In the Mailgun API connector, configure:

API tab:

Host: https://api.mailgun.net
Path: v3/{domain_name}/messages
Method: POST
Path {domain_name): sandbox1947004bd8a14996bc8610978bce37e7.mailgun.org
Header {Content-Type}: Multipart/form-data
Multi Part Data:

{

    "from": {{ message.from }},
    "to": {{ message.to }},
    "subject": {{ message.subject}},
    "text": {{ message.text }}
  }
}

Example response:

  "status": 200,
  "statusMessage": "",
  "body": {
    "id": "<20250319125318.152d650c9d0e220e@sandbox1947004bd8a14996bc8610978bce37e7.mailgun.org>",

    "x-server": "influx",
    "x-xss-protection": "1; mode=block"
  }
}

Attaching files to the email

You can attach one or more files to your email.

Single attachment

Add the attachment field to the JSON body, as shown below:

{
  "fields": {
    "from": "Mailgun Sandbox <[email protected]>",
    "to": "John Doe <[email protected]>",
    "subject": "Hello!",
    "html":"<h1>Hello</h1><p>This is the email content.</p>",
    "attachment": {{ message.fileName}}
  }
}

Multiple attachments

Each attachment must have a unique identifier while maintaining attachment as the base name. You can use variations such as attachmentPDF, attachment2, or attachment_2. See the example:

{
  "fields": {
    "from": "Mailgun Sandbox <[email protected]>",
    "to": "Digibee <[email protected]>",
    "subject": "Hello!",
    "html":"<h1>Hello</h1><p>This is the email content.</p>",
    "attachment": {{ message.fileName}},
    "attachment2": {{ message.fileName2}}
  }
}

If multiple attachments are sent without unique identifiers, only the last attachment will be included in the email.

Retrieving a paginated list of events

Mailgun tracks every inbound and outbound message event and retains this data for at least three days. You can retrieve a paginated list of these events.

For this example, we filter events of type delivered and opened.
