PYostal: Postal API Client

This library helps you use the Postal API in Python 3.9 (and above) to send Emails, get Message Details & Deliveries and Implement Events to handle Server Webhooks.

It uses Requests the simple, yet elegant HTTP library to handle all the http sorcery.

Installing Requests and Supported Versions

PYostal is available on PyPI:

$ python -m pip install pyostal

PYostal officially supports Python 3.9+.

Usage

Using the Client

You will need an API Credential from your Postal Installation to use the API Client.

from pyostal.client import Client

# Create a new Postal client using the server key of your Postal Installation.
client = Client('https://postal.yourdomain.com', 'your-api-key')

# Optional: You can add any aditional Headers for your API installation
# (Maybe Authorization)
# You just add a dict with your headers:
headers = {
    'Authorization' => 'Basic RTYtaO54BGBtcG9yYWwyMDIw'
}

client = Client('https://postal.yourdomain.com', 'your-api-key', headers)

#Or you can add them manually to a Client Instance:
client.headers = headers

Sending an Email

Sending an email is simple. You can follow the example below:

# Create a dict with the message:
payload = {
    'to': ['mail@example.com'],
    'from_address': 'othermail@example.com',
    'reply_to': 'reply-to@example.com',
    'subject': 'This is a subject',
    'plain_body': 'This is a body'
}

#send it using the client. that's it
response = client.send(payload)

Or Create a new Email instance and add manually each of the Mail attributes

from pyostal.emails import Email

email = Email({
    'to': ['mail@example.com'],
    'bcc': ['test1@example.com', 'test2@example.com'],
    'from_address': 'othermail@example.com',
    'reply_to': 'reply-to@example.com',
    'subject': 'This is a subject',
    'plain_body': 'This is a body'
})

email.add_cc('emailcc@example.com')
email.html_body = "<p>This is a HTML body</p>"

# Here we get a pyostal.response.Response instance
response = client.send(Email)
