# March 2021 Features in Interaction Studio

The following functionality was released in March, 2021.

## Server-Side Templates and Campaigns

Interaction Studio provides clients with the ability to configure testing and personalization at the server-to-server level. As of the most recent Interaction Studio release, the server-side campaign system can leverage a campaigns and templates system that mirrors the configuration process for Interaction Studio web campaigns. Key components of the release included:

- An in-app template builder interface for developers to construct Server-Side templates (in-app template editor also added for web templates)
- An enhanced in-app Server-Side campaign configuration screen for business users to apply the server-side templates
- A new application rule for business users to target certain experiences to multiple applications within a single campaign (e.g. POS, CRM, Mobile)

Business users can now collaborate with their development team to easily configure a single campaign that extends across multiple touch-points. Business user documentation on campaign building is [Server-Side Campaigns](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_server_side_campaign.htm&release=264.0.0&type=5 "Server-side campaigns integrate testing and personalization at the server-to-server level. While Marketing Cloud Personalization handles the campaign logic, you need a developer to write the code to call the appropriate APIs and provide information about the website visitor.") and developer documentation is available on the Interaction Studio [developer documentation](https://developer.salesforce.com/docs/marketing/personalization/guide/server-side-campaigns-templates.html) site.
