# Apprise API
Take advantage of [Apprise](https://github.com/caronc/apprise) through your network with a user-friendly API.
- Send notifications to more then 50+ services.
- An incredibly lightweight gateway to Apprise.
- A production ready micro-service at your disposal.
Apprise API was designed easily fit into existing (and new) eco-systems that are looking for a simple notification solution.

## API Details
| Path | Description |
|------------- | ----------- |
| `/add/{KEY}` | Saves Apprise Configuration (or set of URLs) to the persistent store.<br/>*Parameters*<br/>:small_red_triangle: **urls**: Used to define one or more Apprise URL(s). Use a comma and/or space to separate one URL from the next.<br/>:small_red_triangle: **config**: Provide the contents of either a YAML or TEXT based Apprise configuration.<br/>:small_red_triangle: **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}` | Removes Apprise Configuration from the persistent store.
| `/get/{KEY}` | 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}` | Sends a notification based on the Apprise Configuration associated with the specified *{KEY}*.<br/>*Parameters*<br/>:small_red_triangle: **body**: Your message body. This is the *only* required field.<br/>:small_red_triangle: **title**: Optionally define a title to go along with the *body*.<br/>:small_red_triangle: **type**: Defines the message type you want to send as. The valid options are `info`, `success`, `warning`, and `error`. If no *type* is specified then `info` is the default value used.<br/>:small_red_triangle: **tag**: Optionally notify only those tagged accordingly.
### API Notes
- `{KEY}` must be 1-64 alphanumeric characters in length. In addition to this, the underscore (`_`) and dash (`-`) are also accepted.
- You must `POST` to URLs defined above in order for them to respond.
- Specify the `Content-Type` of `application/json` to use the JSON support.
- There is no authentication required to use this API; this is by design. It's intention is to be a lightweight and fast micro-service parked behind the systems designed to handle security.
- There are no persistent store dependencies for the purpose of simplicity. Configuration is hashed and written straight to disk.
### Environment Variables
The use of environment variables allow you to provide over-rides to default settings.
| Variable | Description |
|--------------------- | ----------- |
| `APPRISE_CONFIG_DIR` | Defines the persistent store location of all configuration files saved. By default:<br/> - Content is written to the `apprise_api/var/config` directory when just using the _Django_ `manage runserver` script.
| `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.
| `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 then one host.
| `DEBUG` | This defaults to `False` however can be set to `True`if defined with a non-zero value (such as `1`).
## Container Support
A `docker-compose.yml` file is already set up to grant you an instant production ready simulated environment:
```bash
# Docker Compose
docker-compose up
```
You can now access the API at: `http://localhost:8000/` from your browser.
## 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):
./manage.py runserver
```
You can now access the API at: `http://localhost:8000/` from your browser.
Some other useful development notes:
```bash
# Check for any lint errors
flake8 apprise_api
# Run unit tests
pytest apprise_api
```
## Micro-Service Integration
Perhaps you run your own service and the only goal you have is to add notification support to it. Here is an example:
```python
import requests
import os
# Get your URLs from your end users. They just need
# to be a comma/space separated list (if there is more than one).
# Perhaps they're located in an environment variable:
urls = os.environ.get('NOTIFICATION_URLS', 'windows://')
if urls:
# Think of a key that best describes your purpose and/or program.
# Alternatively; you can make the key based on the users so they
# can each store their configuration.
key = 'my-program-name'
# POST our data:
requests.post(
'http://localhost:8000/add/{}'.format(key),
data={'urls': urls},
)
```
Now when you want to trigger a notification (sent from the Apprise API server), just do the following:
```python
# The minimum notify requirements are to have just provided the 'body':
requests.post(
'http://localhost:8000/notify/{}'.format(key),
data={'body': 'test message'},
)
```
## Apprise Integration
### 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 -body="test message" --config=http://localhost:8000/get/{KEY}
```
### AppriseConfig() Pull Example
Using the Apprise Library through Python, you can easily pull your saved configuration off of the API 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')
```
