Get phone and SMS alerts fromAssertible
Assertible raises the alarm — Spike makes sure a human hears it. Every Assertible 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 Assertible for monitoring and Spike for on-call and incident management. Walk me through connecting them: create a Assertible integration in Spike, copy its webhook URL, and add that webhook to Assertible alert settings. Then help me send a test alert to confirm incidents show up in Spike.
What is Assertible?
Assertible 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, 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 Assertible alerts
Every Spike integration is a unique webhook URL. Paste it into Assertible and alerts start flowing — no agents, no code.
Step 1: Create a Assertible integration in Spike
In your Spike dashboard, open Integrations and choose Assertible. Spike generates a unique webhook URL for this integration — copy it.
Step 2: Add the webhook in Assertible
Open the alert or notification settings in Assertible, add a webhook endpoint, and paste your Spike webhook URL.
Step 3: Send a test alert
Trigger a test from Assertible. The alert lands in Spike as an incident and your on-call team is alerted immediately.
That's it — Assertible alerts now page whoever is on call.
