@Andre601,

To get the title of the PR, you can use the expression “github.event.pull_request.title” to get it from the github context, when the workflow is running on the events for pull request.
For example:

echo "The title of PR is: ${{ github.event.pull_request.title }}"

To get the latest commit on the PR, you can do as the steps below:

• Use the “List commits on a pull request” API to list all the commits on current PR, and save the response as JSON.
• Use jq filter to get the latest commit from the commits list (the list is a JSON array). Generally, the latest commit is the last element of the array, so you need to get the index (length - 1) of this element.
  The following is a simple demo as reference:

on: pull_request
jobs:

job1:

name: Test

if: ${{ github.event_name == 'pull_request' }}

runs-on: ubuntu-latest

steps:

- name: List commits on the pull request

run: |

response=$(curl --request GET 

--url 'https://api.github.com/repos/${{ github.repository }}/pulls/${{ github.event.pull_request.number }}/commits' 

--header 'Authorization: token ${{ secrets.GITHUB_TOKEN }}' 

--header 'Accept: application/vnd.github.v3+json' 

--header 'Content-Type: application/json')
      echo $response > response.json

  - name: Get latest commit
    run: |
      echo "Get length of the array:"
      length=$(jq 'length' response.json)

      echo "Get index of the latest commit:"
      index=$(($length - 1))

      echo "Get context of the latest commit:"
      latest_commit=$(jq --argjson index $index '.[$index]' response.json)
      echo "$latest_commit"

      echo "Get commit message of the latest commit:"
      latest_commit_message=$(echo "$latest_commit" | jq -r '.commit.message')
      echo "$latest_commit_message"

      echo "Get commit SHA of the latest commit:"
      latest_commit_sha=$(echo "$latest_commit" | jq -r '.sha')
      echo "$latest_commit_sha"
