GitHub Action to create event using Microsoft Graph

Creates an event in a user's calendar when an event occurs. This action can be used when say for example a pull request is created and some one has to review it. Creating an event in their calendar will prompt them a notification.

What it does

Pre requisites

This action uses Microsoft Graph to create an event. So please make sure that you register an application in Azure AD, provide that app Calendars.ReadWrite permissions and create a client secret for that.

In your GitHub repo create 3 secrets with the following information:

• TENANT_NAME - The name of your Office 365 tenant (e.g. contoso.onmicrosoft.com)
• APP_ID - The Id of the app registration created above
• APP_SECRET - A secret of the app registration created above.

Usage

Below is a workflow code

name: MS Graph Event

on: [pull_request]

jobs:
  create-event:
    runs-on: ubuntu-latest
    name: Create Event
    steps:
    - name: Create event on the next day
      uses: anoopt/ms-graph-create-event@v1
      env:
        TENANT_NAME: ${{ secrets.TENANT_NAME }}
        APP_ID: ${{ secrets.APP_ID }}
        APP_SECRET: ${{ secrets.APP_SECRET }}
      with:
        subject: 'Review pull request'
        body: 'A new PR has been submitted on ${{ github.repository }} from ${{ github.actor }}. Please review it.'
        emailaddress: 'user@contoso.onmicrosoft.com'

When there is a pull request, the above workflow will create an event for user '[email protected]' on the next day from 12:00 to 13:00 (automatic as no start or end is specified).

More Information

All of the information attached to an event is available in the github.event variable. To see the possible values, you can use the following step in your workflow:

- run: echo '${{ toJson(github.event) }}'

name: MS Graph Event

on: [push]

jobs:
  create-event:
    runs-on: ubuntu-latest
    name: Create Event
    steps:
    - name: Checkout
      uses: actions/checkout@v1
    - name: Create event on the specified day and time
      uses: anoopt/ms-graph-create-event@v1
      env:
        TENANT_NAME: ${{ secrets.TENANT_NAME }}
        APP_ID: ${{ secrets.APP_ID }}
        APP_SECRET: ${{ secrets.APP_SECRET }}
      with:
        subject: 'Code pushed'
        body: 'Some files have been pushed on ${{ github.repository }} from ${{ github.actor }}. Please find the details here ${{ github.event.compare }}.'
        emailaddress: 'user@contoso.onmicrosoft.com'
        start: '2019-12-04T14:30:00'
        end: '2019-12-04T15:00:00'
