We have meanwhile 100+ verified examples of connecting 3rd party tools to SIGNL4. You can find more in our Integrations section.
Nonetheless, the easiest way to connect your 3rd party system to SIGNL4 and to trigger mobile alerting flows is to send an email. Which allows for connecting almost any system. Each team in SIGNL4 gets a dedicated email address, e.g. firstname.lastname@example.org. Send an email with any content to it and it gets translated into a mobile alert workflow.
Additionally, the webhook can be used for connecting modern IT systems while the REST API provides for deeper integration and 3rd party control of functions in SIGNL4. Please, find related information on integrations and the API here.
We have also started to roll out 2-way connectors for widely used 3rd party tools, e.g. for IT monitoring or IT service desk management. You will find those connector apps in the SIGNL4 apps section when you log into the account management portal: https://account.signl4.com/manage/Apps
