How to add your first media in Node?

This guide explains how to create your first media in the Pubstack Node platform, whether it’s a website or a mobile app.

Start by navigating to the Media & Stacks menu. Click on “Add media” in the top-right corner, and fill out the form by writing your media's name and selecting an Environment :

Web : Integration on a website by using Prebid JS and the Prebid Server adapter (could be a web app)

iOS / Android : Integration in a native iOS/Android app using the Prebid Mobile SDK (Swift / Kotlin)

The name of your media can be edited later, but the environment can’t be changed.

Once validated, a setup message will appear, providing the first integration elements — including your Media ID and configuration snippet.

You can then refer to the integration documentation depending on your environment: Web or In-App

Web :

App (iOS example) :

After closing the integration message, click on the media you just created to open its configuration page. Depending on your environment, you’ll be able to add either : - Web ad units - In-App ad units

Ad units are shared resources: they aren’t linked to a single media and can be used across all medias of the same environment (Web or In-App).

In-app ad units can be used for both Android and iOS media.

🖥️ For web environment :

Simply fill out the form :

You can create multiple ad units here, or copy and paste them from a file. Please note that spaces in ad unit names aren’t supported.

You can add more later if needed.

🎥 You can also find a video recap of website and ad units creation below.

📱 For app environment :

You’ll be redirected to the ad unit section.

Enter your ad unit name (used as configId in your app) and select a format (Banner or Interstitial).

Then click on “Validate”.

After creating all necessary ad units, you can return to your app configuration via the Media & Stacks menu.

🚀 You're almost there! Let's move on to the next step: adding bidders.
