Hi , I am creating a workflow for Github that whenever there’s a new Pull request, it will automatically have a label. There’s no option for that action in Pipedream, is there a simpler way to do it or any Github API that I can use?

Yes, you can use the GitHub API to add a label to a new pull request. First, set up a workflow with the “New Pull Request (Instant)” trigger from the GitHub app. Here’s how: 1. Search for the GitHub app from the trigger menu 2. Select the New Pull Request (Instant) trigger 3. Connect your GitHub account 4. Select a Repo or pass a string from a previous step. 5. Follow the instructions on the trigger configuration screen. You may need to generate a test event from GitHub to get real data to test your workflow. Next, add a code step to make an API request to add a label to the new pull request. You can use the following code as a starting point: import { axios } from "@pipedream/platform"; export default defineComponent({ async run({ steps, $ }) { const pullRequest = steps.trigger.event; const repo = pullRequest.repository; const issueNumber = pullRequest.number; const labelName = "your-label-name"; // Replace with the desired label name const url = `https://api.github.com/repos/${repo.owner.login}/${repo.name}/issues/${issueNumber}/labels`; const headers = { Authorization: `Bearer ${steps.trigger.token}`, "Content-Type": "application/json", }; const data = { labels: [labelName], }; await axios($, { method: "POST", url, headers, data, }); }, }); Replace your-label-name with the label you want to add to the pull request. This code will add the specified label to the new pull request when the workflow is triggered.

Hi , I’m still learning Python and I’m not sure what to edit or update in the code provided above. Can you check what I did here:

import { axios } from “@Storytell-ai/storytell”;

export default defineComponent({
async run({ steps, $ }) {
const pullRequest = steps.trigger.event;
const repo = pullRequest.repository;
const issueNumber = pullRequest.number;
const labelName = “CR: [Reviewer] review_needed”;

const url = `https://api.github.com/repos/${repo.owner.login}/${repo.name}/issues/${issueNumber}/labels`;

const headers = {
  Authorization: `Bearer ${steps.trigger.token}`,
  “Content-Type”: “application/json”,
};

const data = {
  labels: [labelName],
};

**await** axios($, {
  method: “POST”,
  url,
  headers,
  data,
});

},
});

I noticed a couple of issues in the code you provided. First, you should import axios from @pipedream/platform, not from @Storytell-ai/storytell. Second, use regular double quotes instead of curly quotes for strings. Here’s the corrected code: ```
import { axios } from “@pipedream/platform”; export default defineComponent({ async run({ steps, $ }) { const pullRequest = steps.trigger.event; const repo = pullRequest.repository; const issueNumber = pullRequest.number; const labelName = “CR: [Reviewer] review_needed”; const url = https://api.github.com/repos/${repo.owner.login}/${repo.name}/issues/${issueNumber}/labels; const headers = { Authorization: Bearer ${steps.trigger.token}, “Content-Type”: “application/json”, }; const data = { labels: [labelName], }; await axios($, { method: “POST”, url, headers, data, }); }, });

still having errors here: Image 2023-09-05 at 8.19.44 PM

I apologize for the confusion earlier. I reviewed the screenshot you provided and noticed that you’re using the wrong import statement. Please update the import statement to: import { axios } from "@pipedream/platform"; Here’s the corrected code: ```
import { axios } from “@pipedream/platform”; export default defineComponent({ async run({ steps, $ }) { const pullRequest = steps.trigger.event; const repo = pullRequest.repository; const issueNumber = pullRequest.number; const labelName = “CR: [Reviewer] review_needed”; const url = https://api.github.com/repos/${repo.owner.login}/${repo.name}/issues/${issueNumber}/labels; const headers = { Authorization: Bearer ${steps.trigger.token}, “Content-Type”: “application/json”, }; const data = { labels: [labelName], }; await axios($, { method: “POST”, url, headers, data, }); }, });

Still having the same error. Here’s the code I used

I apologize for the confusion earlier. I reviewed the code and the error screenshot you provided. It seems the issue is related to the use of angled brackets < and > in the URL template string. Please remove the angled brackets and try the updated code below: ```
import { axios } from “@pipedream/platform”; export default defineComponent({ async run({ steps, $ }) { const pullRequest = steps.trigger.event; const repo = pullRequest.repository; const issueNumber = pullRequest.number; const labelName = “CR: [Reviewer] review_needed”; const url = https://api.github.com/repos/${repo.owner.login}/${repo.name}/issues/${issueNumber}/labels; const headers = { Authorization: Bearer ${steps.trigger.token}, “Content-Type”: “application/json”, }; const data = { labels: [labelName], }; await axios($, { method: “POST”, url, headers, data, }); }, });

Its still not working. Here’s the error:

I apologize for the confusion earlier. It seems I made a mistake in my response. Since you’re encountering a Python-related error, it appears you’re working with a Python code step instead of a Node.js code step in Pipedream. In that case, you should use the requests library for making HTTP requests in Python. Here’s the corrected Python code for your use case: ```
import requests pull_request = steps.trigger.event repo = pull_request[“repository”] issue_number = pull_request[“number”] label_name = “CR: [Reviewer] review_needed” url = f"https://api.github.com/repos/{repo[‘owner’][‘login’]}/{repo[‘name’]}/issues/{issue_number}/labels" headers = { “Authorization”: f"Bearer {steps.trigger.token}", “Content-Type”: “application/json”, } data = { “labels”: [label_name], } response = requests.post(url, headers=headers, json=data)

Posted thread to Discourse: How to Automatically Add a Label to New Pull Requests in GitHub Using Pipedream or GitHub API?

13

I would like to update the workflow to include pull request that can be labeled as draft first.

14

To update the workflow to label new pull requests as drafts first, you can modify the label name in the code. Here’s an example using the GitHub API with a Node.js code step in Pipedream: ```
import { axios } from “@pipedream/platform”; export default defineComponent({ async run({ steps, $ }) { const pullRequest = steps.trigger.event; const repo = pullRequest.repository; const issueNumber = pullRequest.number; const labelName = “Draft: [Reviewer] review_needed”; const url = https://api.github.com/repos/${repo.owner.login}/${repo.name}/issues/${issueNumber}/labels; const headers = { Authorization: Bearer ${steps.trigger.token}, “Content-Type”: “application/json”, }; const data = { labels: [labelName], }; await axios($, { method: “POST”, url, headers, data, }); }, });

15

I’m using Python to import the data. Here’s my code so far.
pull_request = pd.steps[“trigger”][“event”][“pull_request”]
repo = pd.steps[“trigger”][“event”][“repository”]
issue_number = pull_request[“number”]
label_name = “CR: [Reviewer] review_needed”

url = f”https://api.github.com/repos/{repo[‘owner’][‘login’]}/{repo[‘name’]}/issues/{issue_number}/labels”

headers = {
“Authorization”: f”Bearer {token}“,
“Content-Type”: “application/json”,
}

data = {“labels”: [label_name]}

response = requests.post(url, headers=headers, json=data)

I wanted to add a line that if the Pull Request name has a “Draft” on it it will instead label the Pull request as draft instead of “CR: [Reviewer] review_needed”

16

You can modify your Python code to check if the pull request title contains “Draft” and change the label accordingly. Here’s the updated code: ```
import requests pull_request = pd.steps[“trigger”][“event”][“pull_request”] repo = pd.steps[“trigger”][“event”][“repository”] issue_number = pull_request[“number”] title = pull_request[“title”] if “Draft” in title: label_name = “Draft: [Reviewer] review_needed” else: label_name = “CR: [Reviewer] review_needed” url = f"https://api.github.com/repos/{repo[‘owner’][‘login’]}/{repo[‘name’]}/issues/{issue_number}/labels" headers = { “Authorization”: f"Bearer {token}", “Content-Type”: “application/json”, } data = {“labels”: [label_name]} response = requests.post(url, headers=headers, json=data)

17

how can I update the code above to append the label?

18

To update your Python code to append the label instead of replacing it, you’ll need to first fetch the existing labels and then append the new label to the list. Here’s the updated code: ```
import requests pull_request = pd.steps[“trigger”][“event”][“pull_request”] repo = pd.steps[“trigger”][“event”][“repository”] issue_number = pull_request[“number”] title = pull_request[“title”] if “Draft” in title: label_name = “Draft: [Reviewer] review_needed” else: label_name = “CR: [Reviewer] review_needed” url = f"https://api.github.com/repos/{repo[‘owner’][‘login’]}/{repo[‘name’]}/issues/{issue_number}/labels" headers = { “Authorization”: f"Bearer {token}", “Content-Type”: “application/json”, } # Fetch existing labels get_labels_response = requests.get(url, headers=headers) existing_labels = get_labels_response.json() # Append the new label to the existing labels list labels = [label[“name”] for label in existing_labels] labels.append(label_name) data = {“labels”: labels} response = requests.post(url, headers=headers, json=data)

19

It doesn’t seem to be working. Here’s the code I’m using.
import requests

def handler(pd: “pipedream”):
token = f’{pd.inputs[“github”][“$auth”][“oauth_access_token”]}’
authorization = f’Bearer {token}’
headers = {“Authorization”: authorization, “X-GitHub-Api-Version”: ‘2022-11-28’}
r = requests.get(‘https://api.github.com/user’, headers=headers)
# Export the data for use in future steps

pull_request = pd.steps[“trigger”][“event”][“pull_request”]
repo = pd.steps[“trigger”][“event”][“repository”]
issue_number = pull_request[“number”]
title = pull_request[“title”]

if pd.steps[“trigger”][“event”][“pull_request”][“draft”]:
label_name = “CR: [Creator] draft”
else:
label_name = “CR: [Reviewer] review_needed”

url = f”https://api.github.com/repos/{repo[‘owner’][‘login’]}/{repo[‘name’]}/issues/{issue_number}/labels”

headers = {
“Authorization”: f”Bearer {token}“,
“Content-Type”: “application/json”,
}

# Fetch existing labels
get_labels_response = requests.get(url, headers=headers)
existing_labels = get_labels_response.json()

# Append the new label to the existing labels list
labels = [label[“name”] for label in existing_labels]
labels.append(label_name)

data = {“labels”: labels}

response = requests.post(url, headers=headers, json=data)

I see that you’re using Python code, but Pipedream components are written in Node.js. Let me help you convert the code to a Pipedream component using Node.js and the axios library. import { axios } from "@pipedream/platform"; export default defineComponent({ async run({ steps }) { const token = steps.trigger.event.github.$auth.oauth_access_token; const pull_request = steps.trigger.event.pull_request; const repo = steps.trigger.event.repository; const issue_number = pull_request.number; const title = pull_request.title; const label_name = pull_request.draft ? "CR: [Creator] draft" : "CR: [Reviewer] review_needed"; const url = `https://api.github.com/repos/${repo.owner.login}/${repo.name}/issues/${issue_number}/labels`; const headers = { Authorization: `Bearer ${token}`, "Content-Type": "application/json", }; // Fetch existing labels const get_labels_response = await axios(this, { method: "GET", url: url, headers: headers, }); const existing_labels = get_labels_response.data; // Append the new label to the existing labels list const labels = existing_labels.map((label) => label.name); labels.push(label_name); const data = { labels: labels }; const response = await axios(this, { method: "POST", url: url, headers: headers, data: data, }); return response.data; }, }); This code uses the axios library from the @pipedream/platform package to make the API requests. Replace your Python code with this Node.js code in a Pipedream component, and it should work as expected.
