Quickstart

Send yourself a notification in under a minute. One key, one request.

1 · Get your key

Sign in at youlmk.com or in the app, name your first source (the thing that will send, e.g. deploy.sh) and copy its key. Every source has its own key, so every source gets its own rules.

2 · Send

Plain text becomes the title. JSON lets you set everything else.

$ curl youlmk.com/k/k_7hq2nk3f9qd8w4 -d "deployed"
$ curl youlmk.com/k/k_7hq2nk3f9qd8w4 \
-H "content-type: application/json" \
-d '{ "title": "api deployed · v2.4.1",
"body": "production · 4 min 12 s",
"priority": "normal",
"url": "https://example.com/deploys/2041" }'

The response is { "ok": true, "id": "ntf_…", "receipt": "rcpt_…", "grouped": false, "held": false }. grouped says it joined an open card; held says quiet hours are holding it.

3 · Decide where it lands

By default every notification goes to every destination you have: phones, browsers, email addresses, Slack channels. Narrow it per source or per watch with Deliver to, and set how loud it may be with Reach: Silent, Badge, Banner or Break through.

Free to start: your first 10 notifications and 3 watches, no card, no clock. After that Send is $4 a month.
