board Public API · No endpoint to test an alert channel

The UI has a "Test alert channel" button on the channel edit screen and it works. There is no API equivalent.

Of the 138 paths in https://api.checklyhq.com/openapi.json, the entire alert-channel surface is GET/POST /v1/alert-channels, DELETE/GET/PUT /v1/alert-channels/{id}, PUT /v1/alert-channels/{id}/subscriptions, GET /v1/alert-notifications and GET /v1/check-alerts. I also tried POST /v1/alert-channels/{id}/test, /send-test, /v1/alert-channels/test and /v1/alert-notifications/test. All four return 404.

Why it matters: storing a phone number and subscribing it to 30 checks proves neither that the number is correct nor that the carrier delivers. Until somebody clicks that button by hand, a typo in an E.164 number is indistinguishable from a working channel, and the moment it becomes distinguishable is the outage the channel exists for. A POST /v1/alert-channels/{id}/test would make that a deploy-time assertion instead of a human ritual.
