Custom request headers for URL Monitors

Hi Checkly team,

We'd like to request support for custom request headers in URL Monitors.

Use case:

Our infrastructure routes incoming requests based on a custom HTTP header, which directs each request to the correct backend/environment. Without the header, the request doesn't reach the intended target, so a plain GET to the URL doesn't reflect the real health of the service.

Request:

Allow defining one or more custom headers (key/value) on a URL Monitor, ideally with support for environment variables/secrets for the values.

Why URL Monitors:

We want the lightweight, simple uptime check that URL Monitors provide. Today our only option is a full API Check, which adds unnecessary overhead for what is essentially a basic availability check.

Thanks,
