GitHub Actions - Print GitHub Webhook events and payloads

Many times, I want to know what the Json payload looks like when an event occurs on GitHub that triggers a GitHub Actions workflow.

In the past, I used to setup a Webhook that sends the json payload to my local server. Now, I use GitHub Actions to print the whole json payload.

The delete event sends a delete webhook payload.

To print out the payload, I use the workflow below:

name: Dump GH events and payloads

on:
  delete

jobs:
  test:
    name: debug
    runs-on: [ubuntu]

    steps:
      - name: print whole context
        env:
          GITHUB_CONTEXT:  ${{ toJson(github) }} 
          VARS_CONTEXT:  ${{ toJson(vars) }} 
        run: |
          echo "GITHUB_CONTEXT is $GITHUB_CONTEXT"
          echo "VARS_CONTEXT is $VARS_CONTEXT"
          echo "delete event is  ${{ GITHUB_CONTEXT.event }} "
