Send a SIGNL4 Test Alert

Send a test alert to a SIGNL4 team.

Setup and use

In Open Flow, bind the full SIGNL4 team webhook URL to the secret Variable SIGNL4_WEBHOOK_URL in Send the test alert. In n8n, connect a SIGNL4 team credential. Edit the title and message to suit your test, then run manually. The webhook URL contains the team secret; restrict access to execution logs.

Behavior

Each run sends one new alert with the example title “Sample Title” and message “This is a test alert sent from n8n to SIGNL4”. An accepted request does not confirm that a person received the notification. If the send result is unknown, check SIGNL4 before retrying to avoid a duplicate alert.

Inspiration & credits

Changes to the source

Open Flow sends the equivalent JSON payload to the team webhook instead of using the n8n SIGNL4 node.
