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.
Test It
Start the workflow and when the SIGNL4 node is executed, an alarm will be sent to your SIGNL4 team.
Tips & Tricks
Alert Optimization
SIGNL4 can further increase the visibility of alerts through its Signals and Services categories. Augmenting the color and icon of alerts will provide more relevant information at a glance without having to open the alert. You can also augment ticket alerts with maps or change the subject or message to a more comprehensible content.
Alert categories in SIGNL4 also allow to group ticket alerts and even to route those ticket notifications to your staff based on skills or other criteria. Screenshots show how to override text, colors and titles are triggered by keywords set within the mobile app.
