Get phone and SMS alerts fromSemaphore
Semaphore raises the alarm — Spike.sh makes sure a human hears it. Every Semaphore alert becomes an incident with on-call schedules, escalations, and alerts on phone, SMS, Slack, email, WhatsApp, and Teams.
Set up with AI
I use Semaphore for monitoring and Spike.sh for on-call and incident management. Walk me through connecting them: create a Semaphore integration in Spike.sh, copy its webhook URL, and add that webhook to Semaphore alert settings. Then help me send a test alert to confirm incidents show up in Spike.sh.
What is Semaphore?
Semaphore keeps watch over your systems and raises an alert the moment something goes wrong — a failed check, an error spike, a service that stops responding.
Connected to Spike.sh, those alerts become incidents: the right on-call person gets a phone call and SMS within seconds, similar incidents are grouped to cut the noise, and everything is tracked until it is resolved.
How to set up Semaphore alerts
Every Spike.sh integration is a unique webhook URL. Paste it into Semaphore and alerts start flowing — no agents, no code.
Step 1: Create a Semaphore integration in Spike.sh
In your Spike.sh dashboard, open Integrations and choose Semaphore. Spike.sh generates a unique webhook URL for this integration — copy it.
Step 2: Add the webhook in Semaphore
Open the alert or notification settings in Semaphore, add a webhook endpoint, and paste your Spike.sh webhook URL.
Step 3: Send a test alert
Trigger a test from Semaphore. The alert lands in Spike.sh as an incident and your on-call team is alerted immediately.
That's it — Semaphore alerts now page whoever is on call.
