The Pillow SDK lets you run research studies inside your app or website. You can identify users, attach durable properties, and present hosted Pillow studies without sending people to a separate landing page.

​
What you can do

  • Present studies inside your app or website
  • Launch studies automatically to targeted user cohorts via audience targeting
  • Identify users with an external ID and custom properties
  • Manage sessions: reset on logout, handle the lifecycle

​
When to use the SDK

Reach for the SDK when you want studies to appear in context, inside your product, and to target users by who they are and what they’ve done. If you just need to send a study to people over email, chat, or social, a shareable link is simpler and needs no integration.
