Integrations and APIs

SIGNL4 is your SaaS platform offering one of the most open and flexible APIs you can find. It caters to both – simple and advanced integrations – meeting your every need.

How to connect to SIGNL4


Email (SMTP)

Each team in SIGNL4 gets a dedicated email address ( {teamsecrect} [at] ). Simply send an email to this address to notify an entire team or team members on duty. Global email addresses with routing rules can be configured as well.

Inbound Webhook

Send alert notifications to your SIGNL4 team via a webhook. The inbound webhook supports JSON payloads to pass parameters for customizing and enriching alerts. The inbound webhook reference gets you started! Also, check out our code samples.


Make SIGNL4 even better! Developers can implement additional functionality or seamlessly integrate existing services with SIGNL4. Read the full API Reference for details.

Outbound Webhook

SIGNL4 can notify your apps and services on events (duty status change, acknowledgements, etc) by calling external webhooks. Your webhook endpoint URLs can be registered either in the SIGNL4 account management or through the REST API. Further documentation is available here.
