Get started with Signalgrid Explore our API

Signalgrid provides an official Python library that allows you to send notifications from scripts, services, and automation workflows.

The library works well with:

Python scripts
Automation tools
Monitoring systems
CI/CD pipelines
Backend services

Repository: https://github.com/signalgridco/signalgrid-python

Installation

Install the Signalgrid Python package using pip:

pip install signalgrid

This installs the Signalgrid client library and its dependencies.

Basic Usage

To send a notification, create a Signalgrid client and call send().

from signalgrid import Client

client = Client("YOUR_CLIENT_KEY")

response = client.send({
    "channel": "YOUR_CHANNEL_TOKEN",
    "title": "Server Alert",
    "body": "Database connection lost",
    "type": "CRIT",
    "critical": True
})

print(response)

Parameters

Parameter

Description

channel

Channel token that receives the notification

title

Notification title

body

Notification message

type

Notification type (INFO, WARN, CRIT, SUCCESS)

critical

Sends a critical notification

Example types:

"type": "INFO"
"type": "WARN"
"type": "CRIT"
"type": "SUCCESS"

Example: Script Notification

The following example sends a notification when a script finishes.

from signalgrid import Client

client = Client("YOUR_CLIENT_KEY")

client.send({
    "channel": "YOUR_CHANNEL_TOKEN",
    "title": "Backup Completed",
    "body": "Nightly backup finished successfully",
    "type": "SUCCESS"
})

Example: Error Alert

from signalgrid import Client

client = Client("YOUR_CLIENT_KEY")

client.send({
    "channel": "YOUR_CHANNEL_TOKEN",
    "title": "Server Down",
    "body": "The web server stopped responding",
    "type": "CRIT",
    "critical": True
})

This sends a critical alert that bypasses Do Not Disturb on supported devices.

Using Environment Variables (Recommended)

Avoid hardcoding your client key.

Instead use environment variables:

import os
from signalgrid import Client

client = Client(os.getenv("SIGNALGRID_CLIENT_KEY"))

Example environment variable:

export SIGNALGRID_CLIENT_KEY=abc123
