ap·prise / verb

To inform or tell (someone). To make one aware of something.

Apprise allows you to send a notification to almost all of the most popular notification services available to us today such as: Telegram, Discord, Slack, Amazon SNS, Gotify, etc.

• One notification library to rule them all.
• A common and intuitive notification syntax.
• Supports the handling of images and attachments (to the notification services that will accept them).
• It's incredibly lightweight.
• Amazing response times because all messages sent asynchronously.

Developers who wish to provide a notification service no longer need to research each and every one out there. They no longer need to try to adapt to the new ones that comeout thereafter. They just need to include this one library and then they can immediately gain access to almost all of the notifications services available to us today.

System Administrators and DevOps who wish to send a notification now no longer need to find the right tool for the job. Everything is already wrapped and supported within the apprise command line tool (CLI) that ships with this product.

SMS Notifications

SMS Notifications for the most part do not have a both a title and body. They consist of a single body which is usually no more then 160 characters in length. When using Apprise, the title and body are therefore combined into a single message prior to their transmission.

Desktop Notifications

Email Notifications

Apprise have some email services built right into it (such as yahoo, fastmail, hotmail, gmail, etc) that greatly simplify the mailto:// service. See more details here.

Custom Notifications

Installation

The easiest way is to install Apprise from PyPI:

pip install apprise

Apprise is also packaged as an RPM and available through EPEL supporting CentOS, Redhat, Rocky, Oracle Linux, etc.

# Follow instructions on https://docs.fedoraproject.org/en-US/epel
# to get your system connected up to EPEL and then:
# Redhat/CentOS 7.x users
yum install apprise

# Redhat/Rocky Linux 8.x+ and/or Fedora Users
dnf install apprise

You can also check out the Graphical version of Apprise to centralize your configuration and notifications through a manageable webpage.

Command Line Usage

A small command line interface (CLI) tool is also provided with this package called apprise. If you know the server urls you wish to notify, you can simply provide them all on the command line and send your notifications that way:

# Send a notification to as many servers as you want
# as you can easily chain one after another (the -vv provides some
# additional verbosity to help let you know what is going on):
apprise -vv -t 'my title' -b 'my notification body' \
   'mailto://myemail:[email protected]' \
   'pbul://o.gn5kj6nfhv736I7jC3cj3QLRiyhgl98b'

# If you don't specify a --body (-b) then stdin is used allowing
# you to use the tool as part of your every day administration:
cat /proc/cpuinfo | apprise -vv -t 'cpu info' \
   'mailto://myemail:[email protected]'

# The title field is totally optional
uptime | apprise -vv \
   'discord:///4174216298/JHMHI8qBe7bk2ZwO5U711o3dV_js'

CLI Configuration Files

No one wants to put their credentials out for everyone to see on the command line. No problem apprise also supports configuration files. It can handle both a specific YAML format or a very simple TEXT format. You can also pull these configuration files via an HTTP query too! Read more about the expected structure of the configuration files here.

# By default if no url or configuration is specified apprise will attempt to load
# configuration files (if present) from:
#  ~/.apprise
#  ~/.apprise.yaml
#  ~/.config/apprise.conf
#  ~/.config/apprise.yaml
#  /etc/apprise.conf
#  /etc/apprise.yaml

# Also a subdirectory handling allows you to leverage plugins
#  ~/.apprise/apprise
#  ~/.apprise/apprise.yaml
#  ~/.config/apprise/apprise.conf
#  ~/.config/apprise/apprise.yaml
#  /etc/apprise/apprise.yaml
#  /etc/apprise/apprise.conf

# Windows users can store their default configuration files here:
#  %APPDATA%/Apprise/apprise.conf
#  %APPDATA%/Apprise/apprise.yaml
#  %LOCALAPPDATA%/Apprise/apprise.conf
#  %LOCALAPPDATA%/Apprise/apprise.yaml
#  %ALLUSERSPROFILE%\Apprise\apprise.conf
#  %ALLUSERSPROFILE%\Apprise\apprise.yaml
#  %PROGRAMFILES%\Apprise\apprise.conf
#  %PROGRAMFILES%\Apprise\apprise.yaml
#  %COMMONPROGRAMFILES%\Apprise\apprise.conf
#  %COMMONPROGRAMFILES%\Apprise\apprise.yaml

# The configuration files specified above can also be identified with a `.yml`
# extension or even just entirely removing the `.conf` extension altogether.

# If you loaded one of those files, your command line gets really easy:
apprise -vv -t 'my title' -b 'my notification body'

# If you want to deviate from the default paths or specify more than one,
# just specify them using the --config switch:
apprise -vv -t 'my title' -b 'my notification body' \
   --config=/path/to/my/config.yml

# Got lots of configuration locations? No problem, you can specify them all:
# Apprise can even fetch the configuration from over a network!
apprise -vv -t 'my title' -b 'my notification body' \
   --config=/path/to/my/config.yml \
   --config=https://localhost/my/apprise/config

CLI Tagging Support

Apprise allows you to tag your services in your configuration to organize them (e.g., family, devops, critical). You can then filter which services to notify using the --tag (-g) switch.

It is important to understand how Apprise handles multiple tags:

• OR Logic (Union): To notify services that have either Tag A OR Tag B, specify the -g switch multiple times.
• AND Logic (Intersection): To notify services that have both Tag A AND Tag B, separate the tags with a comma.

# OR Logic: Notify any service tagged 'devops' OR 'admin'
apprise -vv -t "Union Test" \
   --config=~/apprise.yml \
   -g devops -g admin

# AND Logic: Notify only services tagged with BOTH 'devops' AND 'critical'
apprise -vv -t "Intersection Test" \
   --config=~/apprise.yml \
   -g devops,critical

## CLI File Attachments

Apprise also supports file attachments too! Specify as many attachments to a notification as you want.
```bash
# Send a funny image you found on the internet to a colleague:
apprise -vv --title 'Agile Joke' \
        --body 'Did you see this one yet?' \
        --attach https://i.redd.it/my2t4d2fx0u31.jpg \
        'mailto://myemail:[email protected]'

# Easily send an update from a critical server to your dev team
apprise -vv --title 'system crash' \
        --body 'I do not think Jim fixed the bug; see attached...' \
        --attach /var/log/myprogram.log \
        --attach /var/debug/core.2345 \
        --tag devteam

CLI Loading Custom Notifications/Hooks

To create your own custom schema:// hook so that you can trigger your own custom code, simply include the @notify decorator to wrap your function.

from apprise.decorators import notify
#
# The below assumes you want to catch foobar:// calls:
#
@notify(on="foobar", name="My Custom Foobar Plugin")
def my_custom_notification_wrapper(body, title, notify_type, *args, **kwargs):
    """My custom notification function that triggers on all foobar:// calls
    """
    # Write all of your code here... as an example...
    print("{}: {} - {}".format(notify_type.upper(), title, body))

    # Returning True/False is a way to relay your status back to Apprise.
    # Returning nothing (None by default) is always interpreted as a Success

Once you've defined your custom hook, you just need to tell Apprise where it is at runtime.

# By default if no plugin path is specified apprise will attempt to load
# all plugin files (if present) from the following directory paths:
#  ~/.apprise/plugins
#  ~/.config/apprise/plugins
#  /var/lib/apprise/plugins

# Windows users can store their default plugin files in these directories:
#  %APPDATA%/Apprise/plugins
#  %LOCALAPPDATA%/Apprise/plugins
#  %ALLUSERSPROFILE%\Apprise\plugins
#  %PROGRAMFILES%\Apprise\plugins
#  %COMMONPROGRAMFILES%\Apprise\plugins

# If you placed your plugin file within one of the directories already defined
# above, then your call simply needs to look like:
apprise -vv --title 'custom override' \
        --body 'the body of my message' \
        foobar:\\

# However you can override the path like so
apprise -vv --title 'custom override' \
        --body 'the body of my message' \
        --plugin-path /path/to/my/plugin.py \
        foobar:\\

You can read more about creating your own custom notifications and/or hooks here.

CLI Environment Variables

Those using the Command Line Interface (CLI) can also leverage environment variables to pre-set the default settings:

Developer API Usage

To send a notification from within your python application, just do the following:

import apprise

# Create an Apprise instance
apobj = apprise.Apprise()

# Add all of the notification services by their server url.
# A sample email notification:
apobj.add('mailto://myuserid:[email protected]')

# A sample pushbullet notification
apobj.add('pbul://o.gn5kj6nfhv736I7jC3cj3QLRiyhgl98b')

# Then notify these services any time you desire. The below would
# notify all of the services loaded into our Apprise object.
apobj.notify(
    body='what a great notification service!',
    title='my notification title',
)

API Configuration Files

Developers need access to configuration files too. The good news is their use just involves declaring another object (called AppriseConfig) that the Apprise object can ingest. You can also freely mix and match config and notification entries as often as you wish! You can read more about the expected structure of the configuration files here.

import apprise

# Create an Apprise instance
apobj = apprise.Apprise()

# Create an Config instance
config = apprise.AppriseConfig()

# Add a configuration source:
config.add('/path/to/my/config.yml')

# Add another...
config.add('https://myserver:8080/path/to/config')

# Make sure to add our config into our apprise object
apobj.add(config)

# You can mix and match; add an entry directly if you want too
# In this entry we associate the 'admin' tag with our notification
apobj.add('mailto://myuser:[email protected]', tag='admin')

# Then notify these services any time you desire. The below would
# notify all of the services that have not been bound to any specific
# tag.
apobj.notify(
    body='what a great notification service!',
    title='my notification title',
)

# Tagging allows you to specifically target only specific notification
# services you've loaded:
apobj.notify(
    body='send a notification to our admin group',
    title='Attention Admins',
    # notify any services tagged with the 'admin' tag
    tag='admin',
)

# If you want to notify absolutely everything (regardless of whether
# it's been tagged or not), just use the reserved tag of 'all':
apobj.notify(
    body='send a notification to our admin group',
    title='Attention Admins',
    # notify absolutely everything loaded, regardless on whether
    # it has a tag associated with it or not:
    tag='all',
)

API File Attachments

Attachments are very easy to send using the Apprise API:

import apprise

# Create an Apprise instance
apobj = apprise.Apprise()

# Add at least one service you want to notify
apobj.add('mailto://myuser:[email protected]')

# Then send your attachment.
apobj.notify(
    title='A great photo of our family',
    body='The flash caused Jane to close her eyes! hah! :)',
    attach='/local/path/to/my/DSC_003.jpg',
)

# Send a web based attachment too! In the below example, we connect to a home
# security camera and send a live image to an email. By default remote web
# content is cached, but for a security camera we might want to call notify
# again later in our code, so we want our last image retrieved to expire(in
# this case after 3 seconds).
apobj.notify(
    title='Latest security image',
    attach='http://admin:password@hikvision-cam01/ISAPI/Streaming/channels/101/picture?cache=3'
)

To send more than one attachment, just use a list, set, or tuple instead:

import apprise

# Create an Apprise instance
apobj = apprise.Apprise()

# Add at least one service you want to notify
apobj.add('mailto://myuser:[email protected]')

# Now add all of the entries we're interested in:
attach = (
    # ?name= allows us to rename the actual jpeg as found on the site
    # to be another name when sent to our receipient(s)
    'https://i.redd.it/my2t4d2fx0u31.jpg?name=FlyingToMars.jpg',

    # Now add another:
    '/path/to/funny/joke.gif',
)

# Send your multiple attachments with a single notify call:
apobj.notify(
    title='Some good jokes.',
    body='Hey guys, check out these!',
    attach=attach,
)

API Loading Custom Notifications/Hooks

By default, no custom plugins are loaded at all for those building from within the Apprise API. It's at the developers discretion to load custom modules. But should you choose to do so, it's as easy as including the path reference in the AppriseAsset() object prior to the initialization of your Apprise() instance.

For example:

from apprise import Apprise
from apprise import AppriseAsset

# Prepare your Asset object so that you can enable the custom plugins to
# be loaded for your instance of Apprise...
asset = AppriseAsset(plugin_paths="/path/to/scan")

# OR You can also generate scan more then one file too:
asset = AppriseAsset(
    plugin_paths=[
        # Iterate over all python libraries found in the root of the
        # specified path. This is NOT a recursive (directory) scan; only
        # the first level is parsed. HOWEVER, if a directory containing
        # an __init__.py is found, it will be included in the load.
        "/dir/containing/many/python/libraries",

        # An absolute path to a plugin.py to exclusively load
        "/path/to/plugin.py",

        # if you point to a directory that has an __init__.py file found in
        # it, then only that file is loaded (it's similar to point to a
        # absolute .py file. Hence, there is no (level 1) scanning at all
        # within the directory specified.
        "/path/to/dir/library"
    ]
)

# Now that we've got our asset, we just work with our Apprise object as we
# normally do
aobj = Apprise(asset=asset)

# If our new custom `foobar://` library was loaded (presuming we prepared
# one like in the examples above).  then you would be able to safely add it
# into Apprise at this point
aobj.add('foobar://')

# Send our notification out through our foobar://
aobj.notify("test")

You can read more about creating your own custom notifications and/or hooks here.

Persistent Storage

Persistent storage allows Apprise to cache re-occurring actions optionaly to disk. This can greatly reduce the overhead used to send a notification.

There are 3 Persistent Storage operational states Apprise can operate using:

1. auto: Flush gathered cache information to the filesystem on demand. This option is incredibly light weight. This is the default behavior for all CLI usage.
   • Developers who choose to use this operational mode can also force cached information manually if they choose.
   • The CLI will use this operational mode by default.
2. flush: Flushes any cache information to the filesystem during every transaction.
3. memory: Effectively disable Persistent Storage. Any caching of data required by each plugin used is done in memory. Apprise effectively operates as it always did before peristent storage was available. This setting ensures no content is every written to disk.
   • By default this is the mode Apprise will operate under for those developing with it unless they configure it to otherwise operate as auto or flush. This is done through the AppriseAsset() object and is explained further on in this documentation.

CLI Persistent Storage Commands

You can provide the keyword storage on your CLI call to see the persistent storage options available to you.

# List all of the occupied space used by Apprise's Persistent Storage:
apprise storage list

# list is the default option, so the following does the same thing:
apprise storage

# You can prune all of your storage older then 30 days
# and not accessed for this period like so:
apprise storage prune

# You can do a hard reset (and wipe all persistent storage) with:
apprise storage clean

You can also filter your results by adding tags and/or URL Identifiers. When you get a listing (apprise storage list), you may see:

The (persistent storage) cache states are:

• unused: This plugin has not commited anything to disk for reuse/cache purposes
• active: This plugin has written content to disk. Or at the very least, it has prepared a persistent storage location it can write into.
• stale: The system detected a location where a URL may have possibly written to in the past, but there is nothing linking to it using the URLs provided. It is likely wasting space or is no longer of any use.

You can use this information to filter your results by specifying URL ID (UID) values after your command. For example:

# The below commands continue with the example already identified above
# the following would match abcd123 (even though just ab was provided)
# The output would only list the 'stale' entry above
apprise storage list ab

# knowing our filter is safe, we could remove it
# the below command would not obstruct our other to URLs and would only
# remove our stale one:
apprise storage clean ab

# Entries can be filtered by tag as well:
apprise storage list --tag=team

# You can match on multiple URL ID's as well:
# The followin would actually match the URL ID's of 1. and .2 above
apprise storage list f 0

When using the CLI, Persistent storage is set to the operational mode of auto by default, you can change this by providing --storage-mode= (-SM) during your calls. If you want to ensure it's always set to a value of your choice.

API Persistent Storage Commands

For developers, persistent storage is set in the operational mode of memory by default.

It's at the developers discretion to enable it (by switching it to either auto or flush). Should you choose to do so: it's as easy as including the information in the AppriseAsset() object prior to the initialization of your Apprise() instance.

For example:

from apprise import Apprise
from apprise import AppriseAsset
from apprise import PersistentStoreMode

# Prepare a location the persistent storage can write it's cached content to.
# By setting this path, this immediately assumes you wish to operate the
# persistent storage in the operational 'auto' mode
asset = AppriseAsset(storage_path="/path/to/save/data")

# If you want to be more explicit and set more options, then you may do the
# following
asset = AppriseAsset(
    # Set our storage path directory (minimum requirement to enable it)
    storage_path="/path/to/save/data",

    # Set the mode... the options are:
    # 1. PersistentStoreMode.MEMORY
    #       - disable persistent storage from writing to disk
    # 2. PersistentStoreMode.AUTO
    #       - write to disk on demand
    # 3. PersistentStoreMode.FLUSH
    #       - write to disk always and often
    storage_mode=PersistentStoreMode.FLUSH

    # The URL IDs are by default 8 characters in length. You can increase and
    # decrease it's value here.  The value must be > 2. The default value is 8
    # if not otherwise specified
    storage_idlen=8,
)

# Now that we've got our asset, we just work with our Apprise object as we
# normally do
aobj = Apprise(asset=asset)
