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 <[email protected]>')
message.set_subject('Example')
message.set_html('Body')
message.set_text('Body')
message.set_from('Doe John <[email protected]>')
status, msg = sg.send(message)
#or
message = sendgrid.Mail(to='[email protected]', subject='Example', html='Body', text='Body', from_email='[email protected]')
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

status, msg = client.asm_groups.get()
Get a single record.
.. code:: python
status, msg = client.asm_groups.get(record_id)
ASM Suppressions
~~~~~~~~~~~~~~~~
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
emails = ['[email protected]', '[email protected]']
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>)
Get suppression groups associated with a given recipient address.
.. code:: python
status, msg = client.asm_suppressions.get(None,<email_address>)
Delete a recipient email from the suppressions list for a group.
status, msg = client.asm_suppressions.delete(<group_id>,<email_address>)
