SIGNL4 Integration with n8n

n8n is a free and open workflow automation tool. It helps you to automate your daily tasks, synchronize data, or to react to certain events. The platform offers various integrations and helps you to create your own no-code / low-code workflows in no time. Pairing the n8n platform with SIGNL4 can enhance your daily operations with an extension to your team wherever it is.

SIGNL4 is a mobile alert notification app for powerful alerting, alert management and mobile assignment of work items. Get the app at https://www.signl4.com.

In the workflow below we send information from a file to SIGNL4. For example, this can be data from a monitoring tool.

Prerequisites

n8n Workflow

In n8n, you can connect anything to everything. In our example we read data from a file and if a certain condition is met we send this information to our SIGNL4 team.

If you would like to use our sample workflow you can just copy the code below, click anywhere in the n8n window, and paste the code there.

SIGNL4 Integration

For the SIGNL4 node you just need to configure your team secret. This is the last part of your webhook URL. For the other settings you can use whatever is suitable for your scenario.

n8n SIGNL4 Node

Test It

Start the workflow and when the SIGNL4 node is executed, an alarm will be sent to your SIGNL4 team.

The alert in SIGNL4 might look like this.
