Carry approved Slack deadline changes into Canvas

Once a deadline adjustment is agreed, capture it in Canvas so the learner's course schedule reflects the decision.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Create assignment override

Creates an assignment override to adjust due/unlock/lock dates for an assignment in a course, targeting specific students (requires `title`), a group, or a course section; at least one target (`student ids`, `group id`, or `course section id`) is required.

Why this helps

An agreed exception can be forgotten during course administration, creating confusion for both the learner and the founder.

  • Record approved timing changes in the course system.
  • Reduce repeated back-and-forth about a deadline decision.
  • Keep the handoff from team agreement to Canvas short.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Canvas to Notis once through the portal.
  • 2Create an automation in the portal or ask Notis to create one conversationally.
  • 3Give Notis one instruction to create a Canvas assignment override only when Slack states an approved change and identifies the assignment and student, group, or section.
  • 4Select Slack Channel Message Received, choose a channel for run reports, and test with one real approved adjustment.

Questions about this workflow

Can this handle an individual student's deadline?

The Canvas action supports a target student, group, or course section. Make the intended target explicit in the Slack message and prompt.

Should tentative requests change Canvas?

Describe that only approved changes qualify, and test the workflow with a tentative request to ensure the prompt is clear.
