How to connect Athanor to your LMS (LTI 1.3)
An LMS admin adds Athanor as an LTI 1.3 tool with its login, launch and JWKS URLs, or in Canvas with the configuration URL https://athanor.arbastro.com/lti/canvas.json. LTI is part of arbastro Suite Ultra.
LTI 1.3 puts Athanor problem sets into your LMS: an instructor adds a problem set as an assignment, students open it from the LMS already identified, and their scores go to the LMS gradebook. It works with Canvas, Moodle, Blackboard and Brightspace.
Needs an account
LTI is part of arbastro Suite Ultra. See Plans.
Note
Athanor's LTI service is live, but it has not yet been tested against a school's own LMS. Contact [email protected] before you roll it out.
The values your LMS asks for
| Field | Value |
|---|---|
| OIDC login initiation URL | https://athanor.arbastro.com/lti/login |
| Redirect URI / target link URI | https://athanor.arbastro.com/lti/launch |
| Public keyset (JWKS) URL | https://athanor.arbastro.com/lti/jwks |

| Scopes | Assignment and Grade Services (lineitem, score, result.readonly) and Names and Role Provisioning (contextmembership.readonly) |
Canvas
Canvas can read Athanor's configuration from a URL:
- In Canvas, open Admin › Developer Keys and add an LTI Key.
- Choose Enter URL and paste:
https://athanor.arbastro.com/lti/canvas.json- Turn the key on and copy its Client ID.
- Install it under Settings › Apps with that Client ID.
The configuration places Athanor under assignment selection and link selection, and asks for an anonymous privacy level: Canvas sends an id, not names or emails.
Dynamic registration
Moodle, Brightspace, Blackboard and Canvas can also register a tool from a single registration URL. Athanor's registration URL carries a one-time token for your organization; ask for it at [email protected].
