Apple Shortcuts

Use the "Get Contents of URL" action. Any Shortcuts automation (arriving somewhere, a time of day, an NFC tag, a Focus turning on) can then schedule a real alarm.

Build the shortcut

  1. Open Shortcuts and create a new shortcut.

  2. Add the action Get Contents of URL.

  3. Set the URL to:

    https://api.signalarm.app/v1/alarms

  4. Expand the action (tap the arrow), set Method to POST.

  5. Under Headers, add two fields:

    Key Value
    Authorization Bearer <API_TOKEN>
    Content-Type application/json

  6. Under Request Body, choose JSON and add the fields:

    Key Type Value
    fire_in Number 300
    title Text Leave now

  7. Run the shortcut once. Your iPhone rings 5 minutes later.

Ask for the delay each time

Put an Ask for Input action (Number) before the URL action, then a Calculate action that multiplies the input by 60 (fire_in is in seconds), and use the calculation result as the value of fire_in. One shortcut then covers "ring me in N minutes" for any N.

Fixed time instead of a delay

Replace fire_in with fire_at and build the value with the Format Date action: choose Custom and use the format string yyyy-MM-dd'T'HH:mm:ssZZZZZ. Feed it a date from Adjust Date (for example, current date plus 1 hour).

Cancel from a shortcut

Save the id from the response (Get Dictionary Value with key id) and send a second Get Contents of URL with Method DELETE to:

https://api.signalarm.app/v1/alarms/<id>

with the same Authorization header.
