[[Gotify]] is developed in [[GO]], which creates single binary executables with no dependencies. It is therefore best practice if we copy or move the executable to a system accessible directory as per best practices.
```CLI
mkdir /etc/gotify
```
```CLI
cp gotify-linux-amd64 /etc/gotify/gotify
```
or
```CLI
mv gotify-linux-amd64 /etc/gotify/gotify
```
only owner can read/write, anyone can execute (see [[Debian#chmod|permissions]])
```CLI
chmod -R 711 /etc/gotify
```
```CLI
wget -O /etc/gotify/config.example.yml https://raw.githubusercontent.com/gotify/server/master/config.example.yml
```
create log directory as per service file reference
```CLI
mkdir /var/log/gotify
```
# Concept
The [[Gotify]] server receives messages from applications, which can then be read by clients (logged-in users). A user must be bound to an application in order to be able to see messages from that application.
# Configuration
> [!cli]+ <code class="g-code">nano /etc/gotify/config.yml</code>
>
>```YAML
server:
keepaliveperiodseconds: 0 # use GO default (15s)
listenaddr: "" # bind on all addresses
port: 80 # http server port number
database:
dialect: sqlite3 # mariadb and postgresql are also supported
connection: /etc/gotify/data/gotify.db # will be created on first use
passstrength: 10 # the bcrypt password strength (higher = better but also slower)
uploadedimagesdir: /etc/gotify/data/images # will be created if it does not exist
pluginsdir: /etc/gotify/data/plugins # leave empty to disable plugins
registration: false # enable/disable registrations (uncertain of its functionality)
>```
>
# Initial Login
Start the server: <code class="g-code">/etc/gotify/gotify</code> - run the server in interactive mode, with real-time message exchange displayed in the console
Access the [[webUI]] from any browser: <code class="o-code">http://192.168.0.222</code> - assuming default port number was not changed in `config.yml`.

Change the admin password; read the [first login](https://gotify.net/docs/first-login) suggestions.

# USERS
Users are required in order to see messages from applications. A user with administrative rights will have full access to create/delete users.
> ***Only the user who created the application is able to see its messages.***
You can create a single user who is named after an application, or you can create a user who is a person, who will then have to be associated with several applications.
> ***Only an admin can manage (create/delete) users***

Custom application images can be uploaded with a maximum suggested size of 512px. Larger the 512px images are not rescaled and therefore uploading large images is not useful (see [image optimisation](https://gotify.net/docs/optimize-images) for more detail).
![[gotify-apps-1.png]]
# CLIENTS
A client is any application which has successfully logged into the [[Gotify]] server. The application can be a browser session (the [[webUI]]) or the [[Gotify]] [[Android]] app.
You can revoke access to the server (e.g if your phone is lost) by deleting the client.

# Start on Boot
> [!cli]+ <code class="g-code">nano /etc/systemd/system/gotify.service</code>
>
>```BASH
>[Unit]
>Description=Gotify Server
>Requires=network.target
>After=network.target
>Documentation=https://gotify.net/docs/systemd
>
>[Service]
>Type=simple
>User=root
>WorkingDirectory=/etc/gotify/data
>ExecStart=/etc/gotify/gotify
>StandardOutput=append:/var/log/gotify/gotify.log
>StandardError=append:/var/log/gotify/gotify-error.log
>Restart=always
>RestartSec=3
>
>[Install]
># installs a hook to use this unit file when the system boots or shuts down
>WantedBy=multi-user.target
>```
>
> Alternatively, create the service file in any location you choose (e.g. `/opt/gotify/gotify.service`) and then link to `/etc/systemd/system`:
> ```CLI
> ln -s /opt/gotify/gotify.service /etc/systemd/system/gotify.service
> ```
start server on boot
```CLI
systemctl enable gotify
```
```CLI
reboot
```
ensure server started with no errors
```CLI
systemctl status gotify
```
reload server, whenever `gotify.service` changes
```CLI
systemctl daemon-reload
```
reload server, whenever `config.yml` changes
```CLI
systemctl restart gotify
```
# Send Message
To test everything works we will send a message to the app we created. In our example we have created an app named `Home Assistant` which has been assigned the token `ANh.Ae1RQCznlqv`.
## Use `CURL`
```CLI
curl "http://192.168.0.222/message?token=ANh.Ae1RQCznlqv" -F "title=HA test message" -F "message=test message sent to Gotify App named Home Assistant" -F "priority=5"
```
![[gotify-message-0.png]]
## Use [[Home Assistant]]
### Text Message (unformatted)
> [!cli]+ <code class="g-code">configuration.yaml</code>
> add the following lines
>```YAML
>notify:
> # a named notification service is required for every HA user who should receive notifications
> - name: gotify_admin # name the service
> platform: rest
> resource: http://192.168.0.222/message # replace with your IPv4
> # resource: http://gotify.domain.tld/message # replace with your domain name
> method: POST
> # method: POST_JSON # required for markdown messages
> headers:
> X-Gotify-Key: ANh.Ae1RQCznlqv # replace the app token value with your gotify app token
> # X-Gotify-Key: !secret gotify_admin_key # use a secret instead of the app token value
> message_param_name: message
> title_param_name: title
> target_param_name: target
>```
>
![[gotify-ha-restart.png]]
To test, go to <span class="fieldname">Developer Tools</span> (service ID is: `notify.gotify_admin`).
![[gotify-ha-message-0.png]]
The message can be viewed in the [[Gotify]] [[webUI]] or [[Android]] app. As a reminder you need to be logged in [[Gotify]] with the user credentials used to register the APP (e.g. Home Assistant).
![[gotify-message-0-ha.png]]
The example above can be used in any [[HA]] script to send important notifications using the [[Gotify]] notification service.
### Markdown Message (formatted)
> [!cli]+ <code class="g-code">configuration.yaml</code>
> add the following lines
>```YAML
>notify:
> # a named notification service is required for every HA user who should receive notifications
> - name: gotify_admin_md # name the service
> platform: rest
> resource: http://192.168.0.222/message
> method: POST_JSON # required for markdown messages
> headers:
> X-Gotify-Key: ANh.Ae1RQCznlqv # replace this key with your gotify app token
> message_param_name: message
> title_param_name: title
> target_param_name: target
> data:
> extras:
> client::display:
> contentType: "text/markdown"
>```
