Create comment on pull request

Question

GitHub's comment API seems to allow you to create comments on a pull request, but only if you supply a specific line number in the diff to comment on. Is there a way to create a comment on the pull request as a whole, the equivalent of typing at the bottom of the pull request screen in GitHub's web interface?

Answer 1

According to Ivan, I was able to do something like:

$ curl -s -H "Authorization: token ${ACCESS_TOKEN}" \
 -X POST -d '{"body": "Your Message to Comment"}' \
 "https://api.github.com/repos/${REPO_OWNER}/${REPO_NAME}/issues/${PR_NUMBER}/comments"

or

$ curl -s -u "${GITHUB_ACCOUNT} \
 -X POST -d '{"body": "Your Message to Comment"}' \
 "https://api.github.com/repos/${REPO_OWNER}/${REPO_NAME}/issues/${PR_NUMBER}/comments"

with password prompt

Using GraphQL API v4, you would need to get the Pull Request id using pullrequest Schema and perform addComment mutation afterwards :

query FindPullRequestID {
  repository(owner:"bertrandmartel", name:"ustream-dl") {
    pullRequest(number:2) {
      id
    }
  }
}

mutation AddPullRequestComment {
  addComment(input:{subjectId:"MDExOlB1bGxSZXF1ZXN0MTU0NzExOTA0",body: "test comment"}) {
    commentEdge {
        node {
        createdAt
        body
      }
    }
    subject {
      id
    }
  }
}

Try it in the explorer

Use this CURL:

curl -s -H "Authorization: token your_token_here" \
 -X POST -d '{"body":"Some Comments"}' \
 "https://api.github.com/repos/{owner}/{repo}/pulls/{pull_number}/reviews"

or Python code:

import requests

headers = {
    'Authorization': 'token your_token_here',
}

data = '{"body":"Some Comments"}'

response = requests.post('https://api.github.com/repos/{owner}/{repo}/pulls/{pull_number}/reviews', headers=headers, data=data)

print (response.json())
