Integrations FAQ

What is the simplest way to implement custom application-level health check assertions?

Most applications have custom logic that needs to be monitored.

The simplest way is to create a scheduled job within your infrastructure that implements your assertions, and have that job check-in with a HeyOnCall Inbound Liveness trigger on success. Your job simply needs to send a HTTP POST request to our API to check in.

Can I implement custom application-level health check assertions if I don’t have a scheduled job system?

Yes. Create a special health check endpoint that asserts your custom logic, and have that endpoint return a 200 OK on success, and a non-OK status code on failure. Then, create an HeyOnCall Outbound Probe to monitor this endpoint.

Can any third-party monitoring tool / APM be used to monitor my application?

Yes, so long as it can send webhooks. Webhooks are just a fancy name for HTTP POST requests.

Can I add my own alert delivery channels?

Yes, you can configure webhooks to have HeyOnCall send your server a POST request when we’re delivering an alert.

However, if you care about reliability, we strongly recommend using our mobile app as the primary alert delivery channel. Adding an external webhook is far more fragile: for one thing, it’s possible that the webhook will fail during the same conditions as your incidents, such as a PaaS provider outage.

What makes HeyOnCall better than alternatives?

Alternative solutions often require you to stitch together separate monitoring and on-call alerting tools using brittle webhooks between them. For example: would you really trust your self-hosted monitoring server to be able to send a POST request to your third-party alerting service exactly when you’re in the middle of a flaky network outage? :facepalm: Not exactly a recipe for reliability.

HeyOnCall integrates website monitoring, heartbeat monitoring, on‑call schedules, and alert delivery in one product, which removes fragile links and makes the overall system more reliable.

Critical alerts. On-call schedules. Escalations. Monitoring for websites, APIs, cron jobs, and SSL certificates. All built-in and battle-tested. Designed for developers, by developers. Simple, flat pricing. Free tier forever.
