1. Add MS_TEAMS_WEBHOOK_URI on your repository's configs on Settings > Secrets. It is the webhook URI of the dedicated Microsoft Teams channel for notification.

2. Add a new step on your workflow code as last step of workflow job:

name: MS Teams Github Actions integration

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - uses: a9650615/ms-teams-notify@main
        if: always() # to let this step always run even if previous step failed
        with:
          github-token: ${{ github.token }}
          webhook-uri: ${{ secrets.MS_TEAMS_WEBHOOK_URI }}

• Always set this step with if: always() when there are steps between actions/checkout@v2 and this step.

• add error message if workflow failed
• add files changed list
• add workflow run duration

Feel free to create issue if you have an idea in mind
