## Screenshots
There is a small built-in *Configuration Manager* that can be optionally accessed through your web browser allowing you to create and save as many configurations as you'd like. Each configuration is differentiated by a unique `{KEY}` that you decide on:
Below is a screenshot of how you can assign your Apprise URLs to your `{KEY}`. You can define both TEXT or YAML [Apprise configurations](https://github.com/caronc/apprise/wiki/config).
Once you've saved your configuration, you'll be able to use the *Notification* tab to send your messages to one or more of the services you defined in your configuration. You can use the tag `all` to notify all of your services regardless of what tag had otherwise been assigned to them.
At the end of the day, the GUI just simply offers a user friendly interface to the same API developers can directly interface with if they wish to.
## Installation
The following options should allow you to access the API at: `http://localhost:8000/` from your browser.
Using [dockerhub](https://hub.docker.com/r/caronc/apprise) you can do the following:
```bash
# Retrieve container
docker pull caronc/apprise:latest
# Start it up:
# /config is used for a persistent store, you do not have to mount
# this if you don't intend to use it.
docker run --name apprise \
-p 8000:8000 \
-v /var/lib/apprise/config:/config \
-d caronc/apprise:latest
```
A `docker-compose.yml` file is already set up to grant you an instant production ready simulated environment:
```bash
# Docker Compose
docker-compose up
```
### Config Directory Permissions
Under the hood, An NginX services is reading/writing your configuration files as the user (and group) `www-data` which generally has the id of `33`. In preparation so that you don't get the error: `An error occured saving configuration.` consider also setting up your local `/var/lib/apprise/config` permissions as:
```bash
# Create a user/group (if one doesn't already exist) owned
# by the user and group id of 33
id 33 &>/dev/null || sudo useradd \
--system --no-create-home --shell /bin/false \
-u 33 -g 33 www-data
# Securely set the directory limiting access to only those who
# are part of the www-data group:
sudo chmod 770 -R /var/lib/apprise/config
sudo chown 33:33 -R /var/lib/apprise/config
# Now optionally add yourself to the group if you wish to be able to view
# contents.
sudo usermod -a -G 33 $(whoami)
# You may need to log out and back in again for the above usermod
# to reflect on you. Alternatively you can just type the following
# and it will work as a temporary solution:
sudo su - $(whoami)
```
Alternatively a dirty solution is to just set the directory with full read/write permissions (which is not ideal in a production environment):
```bash
# Grant full permission to the local directory you're saving your
# Apprise configuration to:
chmod 777 /var/lib/apprise/config
```
## Dockerfile Details
The following architectures are supported: `386`, `amd64`, `arm/v6`, `arm/v7`, and `arm64`. The following tags can be used:
* `latest`: Points to the latest stable build.
* `edge`: Points to the last push to the master branch.
## Apprise URLs
📣 In order to trigger a notification, you first need to define one or more [Apprise URLs](https://github.com/caronc/apprise/wiki) to support the services you wish to leverage. Apprise supports over 80+ notification services today and is always expanding to add support for more! Visit https://github.com/caronc/apprise/wiki to see the ever-growing list of the services supported today.
## API Details
### Stateless Solution
Some people may wish to only have a sidecar solution that does require use of any persistent storage. The following API endpoint can be used to directly send a notification of your choice to any of the [supported services by Apprise](https://github.com/caronc/apprise/wiki) without any storage based requirements:
| Path | Method | Description |
|------------- | ------ | ----------- |
| `/notify/` | POST | Sends one or more notifications to the URLs identified as part of the payload, or those identified in the environment variable `APPRISE_STATELESS_URLS`.
*Payload Parameters*
📌 **urls**: One or more URLs identifying where the notification should be sent to. If this field isn't specified then it automatically assumes the `settings.APPRISE_STATELESS_URLS` value or `APPRISE_STATELESS_URLS` environment variable.
📌 **body**: Your message body. This is a required field.
📌 **title**: Optionally define a title to go along with the *body*.
📌 **type**: Defines the message type you want to send as. The valid options are `info`, `success`, `warning`, and `failure`. If no *type* is specified then `info` is the default value used.
📌 **format**: Optionally identify the text format of the data you're feeding Apprise. The valid options are `text`, `markdown`, `html`. The default value if nothing is specified is `text`.
Here is a *stateless* example of how one might send a notification (using `/notify/`):
```bash
# Send your notifications directly
curl -X POST -d 'urls=mailto://user:pass@gmail.com&body=test message' \
http://localhost:8000/notify
# Send your notifications directly using JSON
curl -X POST -d '{"urls": "mailto://user:pass@gmail.com", "body":"test message"}' \
-H "Content-Type: application/json" \
http://localhost:8000/notify
```
### Persistent Storage Solution
You can pre-save all of your Apprise configuration and/or set of Apprise URLs and associate them with a `{KEY}` of your choosing. Once set, the configuration persists for retrieval by the `apprise` [CLI tool](https://github.com/caronc/apprise/wiki/CLI_Usage) or any other custom integration you've set up. The built in website with comes with a user interface that you can use to leverage these API calls as well. Those who wish to build their own application around this can use the following API end points:
| Path | Method | Description |
|------------- | ------ | ----------- |
| `/add/{KEY}` | POST | Saves Apprise Configuration (or set of URLs) to the persistent store.
*Payload Parameters*
📌 **urls**: Define one or more Apprise URL(s) here. Use a comma and/or space to separate one URL from the next.
📌 **config**: Provide the contents of either a YAML or TEXT based Apprise configuration.
📌 **format**: This field is only required if you've specified the _config_ parameter. Used to tell the server which of the supported (Apprise) configuration types you are passing. Valid options are _text_ and _yaml_.
| `/del/{KEY}` | POST | Removes Apprise Configuration from the persistent store.
| `/get/{KEY}` | POST | Returns the Apprise Configuration from the persistent store. This can be directly used with the *Apprise CLI* and/or the *AppriseConfig()* object ([see here for details](https://github.com/caronc/apprise/wiki/config)).
| `/notify/{KEY}` | POST | Sends notification(s) to all of the end points you've previously configured associated with a *{KEY}*.
*Payload Parameters*
📌 **body**: Your message body. This is the *only* required field.
📌 **title**: Optionally define a title to go along with the *body*.
📌 **type**: Defines the message type you want to send as. The valid options are `info`, `success`, `warning`, and `failure`. If no *type* is specified then `info` is the default value used.
📌 **tag**: Optionally notify only those tagged accordingly.
📌 **format**: Optionally identify the text format of the data you're feeding Apprise. The valid options are `text`, `markdown`, `html`. The default value if nothing is specified is `text`.
| `/json/urls/{KEY}` | GET | Returns a JSON response object that contains all of the URLS and Tags associated with the key specified.
As an example, the `/json/urls/{KEY}` response might return something like this:
```json
{
"tags": ["devops", "admin", "me"],
"urls": [
{
"url": "slack://TokenA/TokenB/TokenC",
"tags": ["devops", "admin"]
},
{
"url": "discord://WebhookID/WebhookToken",
"tags": ["devops"]
},
{
"url": "mailto://user:pass@gmail.com",
"tags": ["me"]
}
]
}
```
You can pass in attributes to the `/json/urls/{KEY}` such as `privacy=1` which hides the passwords and secret tokens when returning the response. You can also set `tag=` and filter the returned results based on a comma separated set of tags. if no `tag=` is specified, then `tag=all` is used as the default.
Here is an example using `curl` as to how someone might send a notification to everyone associated with the tag `abc123` (using `/notify/{key}`):
```bash
# Send notification(s) to a {key} defined as 'abc123'
curl -X POST -d "body=test message" \
http://localhost:8000/notify/abc123
# Here is the same request but using JSON instead:
curl -X POST -d '{"body":"test message"}' \
-H "Content-Type: application/json" \
http://localhost:8000/notify/abc123
```
🏷️ You can also leverage _tagging_ which allows you to associate one or more tags with your Apprise URLs. By doing this, notifications only need to be referred to by their easy to remember notify tag name such as `devops`, `admin`, `family`, etc. You can very easily group more than one notification service under the same _tag_ allowing you to notify a group of services at once. This is accomplished through configuration files ([documented here](https://github.com/caronc/apprise/wiki/config)) that can be saved to the persistent storage previously associated with a `{KEY}`.
```bash
# Send notification(s) to a {KEY} defined as 'abc123'
# but only notify the URLs associated with the 'devops' tag
curl -X POST -d 'tag=devops&body=test message' \
http://localhost:8000/notify/abc123
# Here is the same request but using JSON instead:
curl -X POST -d '{"tag":"devops", "body":"test message"}' \
-H "Content-Type: application/json" \
http://localhost:8000/notify/abc123
```
### API Notes
- `{KEY}` must be 1-64 alphanumeric characters in length. In addition to this, the underscore (`_`) and dash (`-`) are also accepted.
- Specify the `Content-Type` of `application/json` to use the JSON support otherwise the default expected format is `application/x-www-form-urlencoded` (whether it is specified or not).
- There is no authentication (or SSL encryption) required to use this API; this is by design. The intention here is to be a light-weight and fast micro-service.
- There are no additional dependencies (such as database requirements, etc) should you choose to use the optional persistent store (mounted as `/config`).
### Environment Variables
The use of environment variables allow you to provide over-rides to default settings.
| Variable | Description |
|--------------------- | ----------- |
| `APPRISE_CONFIG_DIR` | Defines an (optional) persistent store location of all configuration files saved. By default:
- Configuration is written to the `apprise_api/var/config` directory when just using the _Django_ `manage runserver` script. However for the path for the container is `/config`.
| `APPRISE_STATELESS_URLS` | For a non-persistent solution, you can take advantage of this global variable. Use this to define a default set of Apprise URLs to notify when using API calls to `/notify`. If no `{KEY}` is defined when calling `/notify` then the URLs defined here are used instead. By default, nothing is defined for this variable.
| `APPRISE_STATEFUL_MODE` | This can be set to the following possible modes:
📌 **hash**: This is also the default. It stores the server configuration in a hash formatted that can be easily indexed and compressed.
📌 **simple**: Configuration is written straight to disk using the `{KEY}.cfg` (if `TEXT` based) and `{KEY}.yml` (if `YAML` based).
📌 **disabled**: Straight up deny any read/write queries to the servers stateful store. Effectively turn off the Apprise Stateful feature completely.
| `APPRISE_CONFIG_LOCK` | Locks down your API hosting so that you can no longer delete/update/access stateful information. Your configuration is still referenced when stateful calls are made to `/notify`. The idea of this switch is to allow someone to set their (Apprise) configuration up and then as an added security tactic, they may choose to lock their configuration down (in a read-only state). Those who use the Apprise CLI tool may still do it, however the `--config` (`-c`) switch will not successfully reference this access point anymore. You can however use the `apprise://` plugin without any problem ([see here for more details](https://github.com/caronc/apprise/wiki/Notify_apprise_api)). This defaults to `no` and can however be set to `yes` by simply defining the global variable as such.
| `APPRISE_DENY_SERVICES` | A comma separated set of entries identifying what plugins to deny access to. You only need to identify one schema entry associated with a plugin to in turn disable all of it. Hence, if you wanted to disable the `glib` plugin, you do not need to additionally include `qt` as well since it's included as part of the (`dbus`) package; consequently specifying `qt` would in turn disable the `glib` module as well (another way to acomplish the same task). To exclude/disable more the one upstream service, simply specify additional entries separated by a `,` (comma) or ` ` (space). The `APPRISE_DENY_SERVICES` entries are ignored if the `APPRISE_ALLOW_SERVICES` is identified. By default, this is initialized to `windows, dbus, gnome, macos, syslog` (blocking local actions from being issued inside of the docker container)
| `APPRISE_ALLOW_SERVICES` | A comma separated set of entries identifying what plugins to allow access to. You may only use alpha-numeric characters as is the restriction of Apprise Schemas (schema://) anyway. To exclusivly include more the one upstream service, simply specify additional entries separated by a `,` (comma) or ` ` (space). The `APPRISE_DENY_SERVICES` entries are ignored if the `APPRISE_ALLOW_SERVICES` is identified.
| `SECRET_KEY` | A Django variable acting as a *salt* for most things that require security. This API uses it for the hash sequences when writing the configuration files to disk (`hash` mode only).
| `ALLOWED_HOSTS` | A list of strings representing the host/domain names that this API can serve. This is a security measure to prevent HTTP Host header attacks, which are possible even under many seemingly-safe web server configurations. By default this is set to `*` allowing any host. Use space to delimit more than one host.
| `APPRISE_RECURSION_MAX` | This defines the number of times one Apprise API Server can (recursively) call another. This is to both support and mitigate abuse through [the `apprise://` schema](https://github.com/caronc/apprise/wiki/Notify_apprise_api) for those who choose to use it. When leveraged properly, you can increase this (recursion max) value and successfully load balance the handling of many notification requests through many additional API Servers. By default this value is set to `1` (one).
| `APPRISE_WORKER_COUNT` | Defines the number of workers to run. by default this is calculated based on the number of threads detected.
| `BASE_URL` | Those who are hosting the API behind a proxy that requires a subpath to gain access to this API should specify this path here as well. By default this is not set at all.
| `LOG_LEVEL` | Adjust the log level to the console. Possible values are `CRITICAL`, `ERROR`, `WARNING`, `INFO`, and `DEBUG`.
| `DEBUG` | This defaults to `no` and can however be set to `yes` by simply defining the global variable as such.
## Development Environment
The following should get you a working development environment to test with:
```bash
# Create a virtual environment in the same directory you
# cloned this repository to:
python -m venv .
# Activate it now:
. ./bin/activate
# install dependencies
pip install -r dev-requirements.txt -r requirements.txt
# Run a dev server (debug mode) accessible from your browser at:
# -> http://localhost:8000/
./manage.py runserver
```
Some other useful development notes:
```bash
# Check for any lint errors
flake8 apprise_api
# Run unit tests
pytest apprise_api
```
## Apprise Integration
First you'll need to have it installed:
```bash
# install apprise into your environment
pip install apprise
```
### Apprise CLI Pull Example
A scenario where you want to poll the API for your configuration:
```bash
# A simple example of the Apprise CLI
# pulling down previously stored configuration
apprise -vvv --body="test message" --config=http://localhost:8000/get/{KEY}
```
You can also leverage the `import` parameter supported in Apprise configuration files if `APPRISE_CONFIG_LOCK` isn't set on the server you're accessing:
```nginx
# Linux users can place this in ~/.apprise
# Windows users can place this info in %APPDATA%/Apprise/apprise
# Swap {KEY} with your apprise key you configured on your API
import http://localhost:8000/get/{KEY}
```
Now you'll just automatically source the configuration file without the need of the `--config` switch:
```bash
# Configuration is automatically loaded from our server.
apprise -vvv --body="my notification"
```
If you used tagging, then you can notify the specific service like so:
```bash
# Configuration is automatically loaded from our server.
apprise -vvv --tag=devops --body="Tell James GitLab is down again."
```
If you're server has the `APPRISE_CONFIG_LOCK` set, you can still leverage [the `apprise://` plugin](https://github.com/caronc/apprise/wiki/Notify_apprise_api) to trigger our pre-saved notifications:
```bash
# Swap {KEY} with your apprise key you configured on your API
apprise -vvv --body="There are donut's in the front hall if anyone wants any" \
apprise://localhost:8000/{KEY}
```
Alternatively we can set this up in a configuration file and even tie our local tags to our upstream ones like so:
```nginx
# Linux users can place this in ~/.apprise
# Windows users can place this info in %APPDATA%/Apprise/apprise
# Swap {KEY} with your apprise key you configured on your API
devteam=apprise://localhost:8000/{KEY}?tags=devteam
# the only catch is you need to map your tags on the local server to the tags
# you want to pass upstream to your Apprise server using this method.
# In the above we tied the local keyword `friends` to the apprise server using the tag `friends`
```
We could trigger our notification to our friends now like:
```bash
# Trigger our service:
apprise -vvv --tag=devteam --body="Guys, don't forget about the audit tomorrow morning."
```
### AppriseConfig() Pull Example
Using the [Apprise Python library](https://github.com/caronc/apprise), you can easily access and load your saved configuration off of this API in order to use for future notifications.
```python
import apprise
# Point our configuration to this API server:
config = apprise.AppriseConfig()
config.add('http://localhost:8000/get/{KEY}')
# Create our Apprise Instance
a = apprise.Apprise()
# Store our new configuration
a.add(config)
# Send a test message
a.notify('test message')
```
