SendGrid library for Python

Project description

SendGrid-Python
===============

This library allows you to quickly and easily send emails through
SendGrid using Python.

.. image:: https://travis-ci.org/sendgrid/sendgrid-python.svg?branch=master
:target: https://travis-ci.org/sendgrid/sendgrid-python

Warning
-------

If you upgrade to version ``1.2.x``, the ``add_to`` method behaves differently. In the past this method defaulted to using the ``SMTPAPI`` header. Now you must explicitly call the ``smtpapi.add_to`` method. More on the ``SMTPAPI`` section.

Announcements
-------------

For users of our `Web API v3 endpoints`_, we have begun integrating v3 endpoints into this library. As part of this process we have implemented a test automation tool, TOX_. We are also updating and enhancing the core library code.

In no particular order, we have implemented a `few of the v3`_ endpoints already and would appreciate your feedback.

Thank you for your continued support!

Install
-------

.. code:: python

pip install sendgrid
# or
easy_install sendgrid

Example
-------

.. code:: python

import sendgrid

sg = sendgrid.SendGridClient('YOUR_SENDGRID_USERNAME', 'YOUR_SENDGRID_PASSWORD')

message = sendgrid.Mail()
message.add_to('John Doe <john@email.com>')
message.set_subject('Example')
message.set_html('Body')
message.set_text('Body')
message.set_from('Doe John <doe@email.com>')
status, msg = sg.send(message)

#or

message = sendgrid.Mail(to='john@email.com', subject='Example', html='Body', text='Body', from_email='doe@email.com')
status, msg = sg.send(message)

Error handling
--------------

By default, ``.send`` method returns a tuple ``(http_status_code, message)``,
however you can pass ``raise_errors=True`` to ``SendGridClient`` constructor,
then ``.send`` method will raise ``SendGridClientError`` for 4xx errors,
and ``SendGridServerError`` for 5xx errors.

.. code:: python

from sendgrid import SendGridError, SendGridClientError, SendGridServerError

sg = sendgrid.SendGridClient(username, password, raise_errors=True)

try:
sg.send(message)
except SendGridClientError:
...
except SendGridServerError:
...

This behavior is going to be default from version 2.0.0. You are
encouraged to set ``raise_errors`` to ``True`` for forwards compatibility.

``SendGridError`` is a base-class for all SendGrid-related exceptions.

Usage
~~~~~

To begin using this library create a new instance of `SendGridClient` with your SendGrid credentials or a SendGrid API Key. API Key is the preferred method. API Keys are in beta. To configure API keys, visit https://app.sendgrid.com/settings/api_keys.

.. code:: python

sg = sendgrid.SendGridClient('sendgrid_username', 'sendgrid_password')
# or
sg = sendgrid.SendGridClient('sendgrid_apikey')

WEB API v3
----------

.. _APIKeysAnchor:

`APIKeys`_
~~~~~~~~~~

List all API Keys belonging to the authenticated user.

.. code:: python

client = sendgrid.SendGridAPIClient(os.environ.get('SENDGRID_API_KEY'))
status, msg = client.apikeys.get()

`Advanced Suppression Manager (ASM)`_
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Advanced Suppression Manager gives your recipients more control over the types of emails they want to receive by letting them opt out of messages from a certain type of email.

More information_.

.. _information: https://sendgrid.com/docs/API_Reference/Web_API_v3/Advanced_Suppression_Manager/index.html

ASM Groups
~~~~~~~~~~

status, msg = client.asm_groups.get()

Get a single record.

.. code:: python

status, msg = client.asm_groups.get(record_id)

Create a new suppression group.

.. code:: python

Suppressions are email addresses that can be added to groups to prevent certain types of emails from being delivered to those addresses.

Add recipient addresses to the suppressions list for a given group.

.. code:: python

client = sendgrid.SendGridAPIClient(os.environ.get('SENDGRID_API_KEY'))
group_id = <group_id_number> # If no group_id_number, the emails will be added to the global suppression group

status, msg = client.asm_suppressions.post(group_id, emails)

Get suppressed addresses for a given group.

.. code:: python

status, msg = client.asm_suppressions.get(<group_id>)

Delete a recipient email from the suppressions list for a group.

.. code:: python

status, msg = client.asm_suppressions.delete(<group_id>,<email_address>)

ASM Global Suppressions

Global Suppressions are email addresses that will not receive any emails.

Check if a given email is on the global suppression list.

.. code:: python

client = sendgrid.SendGridAPIClient(os.environ.get('SENDGRID_API_KEY'))
email = ['elmer@thinkingserious.com']
status, msg = client.asm_global_suppressions.get(email)
