How can I send a message directly to my app's inbox using the API without it appearing as a push notification?

To deliver a message straight to your app's Message Inbox without showing a system notification alert, send a silent push via the Pushwoosh API and mark it for Inbox storage.

Here's how to configure this:

1. Use the /createMessage API endpoint: see the createMessage reference. Authorize the request with a Server API token in the auth field. Note that createMessage is deprecated - it still works, but new integrations should use Messaging API v2.

2. Enable silent mode per platform (0 or 1):

   • iOS: "ios_silent": 1
   • Android: "android_silent": 1
   • Huawei (HMS): "huawei_android_silent": 1

   Note: silent-push-to-Inbox is a mobile SDK feature. There is no documented silent key inside chrome_root_params / firefox_root_params - those objects only pass arbitrary custom key/value pairs - so do not rely on them for this use case.

3. Make the message persist in the Inbox: a message is saved to the Inbox when at least one of inbox_date, inbox_days or inbox_image is present.

   • "inbox_date": "YYYY-MM-DD" - a date only. It is the date on which the message is removed: it disappears at 00:00:01 UTC of that date, so the previous day is the last day the user can see it. If omitted, the default removal date is the day after the send date.
   • "inbox_days": N - lifetime in days (up to 30) instead of inbox_date.
   • "inbox_image": "URL" - image shown next to the message in the Inbox.

Example request (silent push stored in the Inbox):

{
  "request": {
    "application": "YOUR_APP_CODE",
    "auth": "YOUR_SERVER_API_TOKEN",
    "notifications": [
      {
        "content": "Your message content for the inbox",
        "devices": ["device_hwid"],
        "ios_silent": 1,
        "android_silent": 1,
        "huawei_android_silent": 1,
        "inbox_date": "2026-12-31"
      }
    ]
  }
}

Important considerations:

• Your app must have the Pushwoosh SDK integrated with Inbox support (InboxUI/InboxKit or your own UI) and must fetch Inbox messages for display.
• Silent pushes are delivered in the background; iOS may throttle background delivery, so do not use them for time-critical content.

Refer to the Pushwoosh SDK documentation for your platform (iOS, Android, Flutter, React Native, and so on) for the client-side Inbox implementation details.
