Introduction

Just recently Canvas added support for the Dynamic Registration of the LTI Advantage . This is a 1 step process for the registration of LTI Tools. It enables Praxis AI to offer a simplified onboarding process for our LTI solution. The process is described in this document. It allows:
  • Administrators to register Pria as an LTI tool in just 1 click and
  • Faculty Staff to create a digital twin for every placement of Pria in their course
This process needs to be done just once for your Canvas instance.

As of July 2024, Canvas doesn’t offer to add or placements or edit the custom properties after the LTI component is installed through Dynamic registration. Therefore, the manual process is possible if you want to use a specific instance of Pria (public institution id) or better control the placements, such as to take advantage of the new ‘top_navigation’ placement, that places Pria in a drawer, similar to the wiki_page,
