# Create push subscriptions

Record a browser's push subscription — the endpoint and the two keys the browser itself minted — so notifications can reach it when the app is closed. Idempotent on the endpoint and it re-attaches the browser to whoever is calling, so a client may send it on every enable.

Access class: `workspace`.

## Endpoint

`POST /v1/push/subscriptions`
