Pushpad - Web Push Notifications

Build Status

Pushpad is a service for sending push notifications from your web app. It supports the Push API (Chrome, Firefox, Opera, Edge) and APNs (Safari).

Features:

  • notifications are delivered even when the user is not on your website
  • users don't need to install any app or plugin
  • you can target specific users or send bulk notifications

Installation

Use pip or easy_install:

pip install pushpad

Getting started

First you need to sign up to Pushpad and create a project there.

Then set your authentication credentials and project:

import pushpad

project = pushpad.Pushpad(auth_token='5374d7dfeffa2eb49965624ba7596a09', project_id=123)
  • auth_token can be found in the user account settings.
  • project_id can be found in the project settings.

Collecting user subscriptions to push notifications

Pushpad offers two different products. Learn more

Pushpad Pro

Choose Pushpad Pro if you want to use Javascript for a seamless integration. Read the docs

If you need to generate the HMAC signature for the uid you can use this helper:

project.signature_for(current_user_id)

Pushpad Express

If you want to use Pushpad Express, add a link to your website to let users subscribe to push notifications:

'<a href="{url}">Push notifications</a>'.format(
    url=project.path()
)

# If the user is logged in on your website you should track its user id to target him in the future
'<a href="{url}">Push notifications</a>'.format(
    url=project.path_for(current_user_id)
)

current_user_id is an identifier (e.g. primary key in the database) of the user currently logged in on your website.

When a user clicks the link is sent to Pushpad, asked to receive push notifications and redirected back to your website.

Sending push notifications

import pushpad

project = pushpad.Pushpad(auth_token='5374d7dfeffa2eb49965624ba7596a09', project_id=123)
notification = pushpad.Notification(
    project,
    body="Hello world!", # max 120 characters
    title="Website Name", # optional, defaults to your project name, max 30 characters
    target_url="http://example.com",  # optional, defaults to your project website
    icon_url="http://example.com/assets/icon.png", # optional, defaults to the project icon
    ttl=604800, # optional, drop the notification after this number of seconds if a device is offline
    require_interaction=True, # optional, prevent Chrome on desktop from automatically closing the notification after a few seconds
    image_url="http://example.com/assets/image.png", # optional, an image to display in the notification content
    custom_data="123", # optional, a string that is passed as an argument to action button callbacks
    # optional, add some action buttons to the notification
    # see https://pushpad.xyz/docs/action_buttons
    actions=(
      {
        'title': "My Button 1", # max length is 20 characters
        'target_url': "http://example.com/button-link", # optional
        'icon': "http://example.com/assets/button-icon.png", # optional
        'action': "myActionName" # optional
      },
    ),
    starred=True, # optional, bookmark the notification in the Pushpad dashboard (e.g. to highlight manual notifications)
    # optional, use this option only if you need to create scheduled notifications (max 5 days)
    # see https://pushpad.xyz/docs/schedule_notifications
    send_at=datetime.datetime(2016, 7, 25, 10, 9, 0, 0), # you need to import datetime and use UTC
    # optional, add the notification to custom categories for stats aggregation
    # see https://pushpad.xyz/docs/monitoring
    custom_metrics=('examples', 'another_metric') # up to 3 metrics per notification
)

# deliver to a user
notification.deliver_to(user_id)

# deliver to a group of users
notification.deliver_to((user1_id, user2_id, user3_id))

# deliver to some users only if they have a given preference
# e.g. only the listed users who have also a interested in "events" will be reached
notification.deliver_to((user1_id, user2_id, user3_id), tags=('events',))

# deliver to segments
# e.g. any subscriber that has the tag "segment1" OR "segment2"
notification.broadcast(tags=('segment1', 'segment2'))

# you can use boolean expressions 
# they must be in the disjunctive normal form (without parenthesis)
notification.broadcast(tags='zip_code:28865 && !optout:local_events || friend_of:Organizer123')
notification.deliver_to((user1_id, user2_id), tags=('tag1 && tag2', 'tag3')) # equal to 'tag1 && tag2 || tag3'

# deliver to everyone
notification.broadcast()

You can set the default values for most fields in the project settings. See also the docs for more information about notification fields.

If you try to send a notification to a user ID, but that user is not subscribed, that ID is simply ignored.

The methods above return a dictionary:

  • 'id' is the id of the notification on Pushpad
  • 'scheduled' is the estimated reach of the notification (i.e. the number of devices to which the notification will be sent, which can be different from the number of users, since a user may receive notifications on multiple devices)
  • 'uids' (deliver_to only) are the user IDs that will be actually reached by the notification because they are subscribed to your notifications. For example if you send a notification to ['uid1', 'uid2', 'uid3'], but only 'uid1' is subscribed, you will get ['uid1'] in response. Note that if a user has unsubscribed after the last notification sent to him, he may still be reported for one time as subscribed (this is due to the way the W3C Push API works).
  • 'send_at' is present only for scheduled notifications. The fields 'scheduled' and 'uids' are not available in this case.
