### `/run-actions`
#### Webhook event: `push`
This endpoint allows the application to run specific actions when a push to a specific branch is made. This way, there's no need to manually run the actions on the server.
The configuration file must contain the `run-actions` field, which is an object with the following format:
```json
"run-actions": {
"owner/repo-name": {
"branch": "main",
"actions": [
{
"name": "action-name",
"command": "command-to-run",
"args": [
"arg1",
"arg2",
"..."
]
}
]
}
}
```
Note: if you don't want to use the `args` field, just leave an empty array such as `"args": []`.
## Nginx Configuration
If you want to use Nginx as a reverse proxy for the application, you can use the following example configuration:
```nginx
server {
listen 80;
server_name services.example.com;
location /gh-wh-handler {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
add_header Front-End-Https on;
proxy_headers_hash_max_size 512;
proxy_headers_hash_bucket_size 64;
proxy_buffering off;
proxy_redirect off;
proxy_max_temp_file_size 0;
rewrite /gh-wh-handler/(.*) /$1 break;
proxy_pass http://127.0.0.1:65001;
}
}
```
This way, you will be able to access the application using the URL `http://services.example.com/gh-wh-handler/end-point`.
