# Creating an Output Feed

An output feed is a generated URL containing all of your product information **plus** the new treatments you've created.

Only one output feed is needed per catalog you manage. To create an output feed, go to the **Output Feeds** tab at the top. Then, click **New Output Feed**. You'll only need to have one output feed per catalog you intend to connect to.

You'll be able to name your output feed, choose the channel you want to generate it for and select [Single Treatment or a Multi-Treatment feed](https://help.marpipe.com/en/articles/8182502-single-treatment-vs-multi-treatment-feeds) mode.

The appropriate treatment mode will already be pre-selected for you depending on the channel you select.

After you click **Create**, you'll be able to start managing your new output feed!

Multi-treatments are currently only available for Meta. All other channels require a Single Treatment feed.

# Manage Fields

By default the enriched output feed will include all of the fields present in your source feed + the new image fields added by Marpipe. This is useful because it allows you to use the Marpipe feeds as your primary data source in an ad platform.

If you'd like to restrict which fields are included in your output feed, you can click **Manage Fields** in the output feed page to toggle fields included or excluded:
