Steps

Steps marked “human step” are ones only you can do: verapli never signs in, submits, pays or accepts terms for you.

  1. Sign in or create a OneSignal account

    Sign in to OneSignal. If you have no account yet, you create it yourself; verapli does not create accounts.

    • Guided by hand
    • Human step: You sign in

    Where: https://dashboard.onesignal.com/login

  2. Create an app

    Create a OneSignal app and configure the platforms (mobile, web, email) you need.

    • Guided by hand
    • Human step: You press submit
    • After: Sign in or create a OneSignal account

  3. Copy the App ID

    In Settings > Keys & IDs copy the App ID. It is a public identifier, safe in client SDK setup.

    • Guided by hand
    • After: Create an app

    verapli captures ONESIGNAL_APP_ID here by plain code: encrypted in your browser, never shown to AI.

  4. Create an App API key

    In Settings > Keys & IDs click Add Key. The key (os_v2_app_...) is shown only once; if lost you must rotate it.

    • Guided by hand
    • Human step: You press submit
    • After: Copy the App ID

    verapli captures ONESIGNAL_API_KEY here by plain code: encrypted in your browser, never shown to AI.
