# Webhook Matrix Notifier
This Python project, Webhook Matrix Notifier, is designed to receive data via webhooks, verify a secret,
and send notifications to a [Matrix](https://matrix.org) room.
The project provides a wsgi-compatible interface at `wmn.wsgi`, which is suitable for use behind a reverse proxy.
## Configuration
An example configuration can be found at `config.yml.example`. By default, the project uses the `config.yml` file
in the current working directory for configuration.
To specify a different configuration file, use the `WMN_CONFIG_PATH` environment variable.
## Running the Command Line Notifier
To notify a room with a simple text/html message,
ensure your credentials are filled out in the configuration file and run:
```bash
python -m wmn.notify -r '!room:matrix.org' "text" "html"
```
The installation of the package, specified by `pyproject.yaml`
will create a shorthand script called "matrix-notify" for this purpose.
## Testing the Webhook Application Locally
1. Start the local webserver using either `env FLASK_APP=wmn.wsgi flask run` or have your IDE start it for you.
2. Send a POST request using curl.
### GitLab
```bash
export URLQUOTED_ROOM=`python3 -c 'from urllib.parse import quote_plus; print(quote_plus("#room:matrix.org"))'`
curl -i -X POST "http://localhost:5000/matrix?room=${URLQUOTED_ROOM}" -H "X-Gitlab-Event: Push Hook" -H "X-Gitlab-Token: 123" -H "Content-Type: application/json" --data-binary @./testrequest_gitlab.json
```
Ensure that the `X-Gitlab-Token` corresponds to the secret provided in the configuration.
### Prometheus
```bash
export URLQUOTED_ROOM=`python3 -c 'from urllib.parse import quote_plus; print(quote_plus("#room:matrix.org"))'`
export URLQUOTED_SECRET=`python3 -c 'from urllib.parse import quote_plus; print(quote_plus("123"))'`
curl -i -X POST "http://localhost:5000/matrix?type=prometheus&secret=${URLQUOTED_SECRET}&room=${URLQUOTED_ROOM}" -H "Content-Type: application/json" --data-binary @./testrequest_prometheus.json
```
Ensure that the secret is passed as a URI parameter.
