Installing the Package

You can install the tool using the following command directly from Github.

pip install git+https://github.com/pfptcommunity/ser-mail-api-python.git

or can install the tool using pip.

# When testing on Ubuntu 24.04 the following will not work:
pip install ser-mail-api

If you see an error similar to the following:

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.

    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.

    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.

    See /usr/share/doc/python3.12/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

You should use install pipx or you can configure your own virtual environment and use the command referenced above.

pipx install ser-mail-api

Creating an API client object

from ser_mail_api.v1 import *

if __name__ == "__main__":
    client = Client("<client_id>","<client_secret>")

Sending an Email Message

import json

from ser_mail_api.v1 import *

if __name__ == "__main__":
    # Load API key
    with open("../ser.api_key", "r") as api_key_file:
        api_key_data = json.load(api_key_file)

    client = Client(api_key_data.get("client_id"), api_key_data.get("client_secret"))

    # Create a new Message object
    message = Message("This is a test email", MailUser("[e-mail]", "Joe Sender"))
    # Add content body
    message.add_content(Content("This is a test message", ContentType.TEXT))
    message.add_content(Content("<b>This is a test message</b>", ContentType.HTML))
    # Add Recipients
    message.add_recipient(MailUser("[e-mail]", "Recipient 1"))
    message.add_recipient(MailUser("[e-mail]", "Recipient 2"))
    # Add CC
    message.add_cc(MailUser("[e-mail]", "Carbon Copy 1"))
    message.add_cc(MailUser("[e-mail]", "Carbon Copy 2"))
    # Add BCC
    message.add_bcc(MailUser("[e-mail]", "Blind Carbon Copy 1"))
    message.add_bcc(MailUser("[e-mail]", "Blind Carbon Copy 2"))

    # Add Base64 Encoded Attachment
    message.add_attachment(Attachment("VGhpcyBpcyBhIHRlc3Qh", Disposition.ATTACHMENT, "test.txt", "text/plain"))

    # Add File Attachment from Disk, if Disposition is not passed, the default is Disposition.ATTACHMENT
    message.add_attachment(FileAttachment(r"C:\temp\file.csv", Disposition.ATTACHMENT))

    # In the following example, we will create a byte stream from a string. This byte stream is converted
    # to base64 encoding within the StreamAttachment object
    text = "This is a sample text stream."

    # Convert the string into bytes
    byte_stream = text.encode("utf-8")

    # Add Byte Stream as Attachment, if Disposition is not passed, the default is Disposition.ATTACHMENT
    message.add_attachment(StreamAttachment(byte_stream,"byte_stream.txt", "text/plain", Disposition.ATTACHMENT))

    result = client.send(message)

    print("HTTP Status", result.get_status())
    print("HTTP Reason", result.get_reason())

    print("Reason:", result.reason)
    print("Message ID:", result.message_id)
    print("Request ID:", result.request_id)

The following JSON data is a dump of the message object based on the code above.
