Pull request

Get a push notification when a pull request is opened, marked ready for review, gets a review request, or is merged.

How it works

Three steps to your first push

STEP 01

Install the recipe

One click in Studio gives you a personal webhook URL.

STEP 02

Paste your URL into GitHub

Add it as a webhook for Pull requests.

STEP 03

Get a push on your phone

With the text, sound and buttons from the recipe.

Setup

How to set up the GitHub pull requests webhook

Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
In your repository (or organization), go to Settings > Webhooks and click Add webhook.
Paste your webhook URL as the Payload URL and set Content type to application/json.https://••••••••/•••••••• your personal URL, shown after install
Enter a secret and copy the same secret into JustPush.
Choose Let me select individual events, tick Pull requests, and save. GitHub sends a ping right away.
Tick **Pull requests** in the webhook's events. Pushes go out when a pull request is opened (not as a draft), marked ready for review, gets a review request, or is merged. Edits, syncs, labels and closes without merging are ignored.
GitHub signs every delivery with your secret (`X-Hub-Signature-256`), and JustPush checks it, so requests that don't come from GitHub are rejected.

The code

What runs when the webhook arrives

Studio calls handleRequest(request) with the incoming webhook and sends the message it returns. It's yours after install; change anything.

Payload

The GitHub pull_request webhook

This is what GitHub sends to your URL for pull requests. It is a sample, trimmed to the fields recipes use.

pull_request · sample.json
 1{
"action": "opened",
"number": 42,
"sender": {
  "login": "sam-lee"
},
"repository": {
  "full_name": "acme/web"
},
"pull_request": {
  "base": {
    "ref": "main"
  },
  "head": {
    "ref": "feature/apple-pay"
  },
  "user": {
    "login": "sam-lee"
  },
  "draft": false,
  "state": "open",
  "title": "Add Apple Pay to checkout",
  "merged": false,

Security

How the GitHub signature is verified

X-Hub-Signature-256

GitHub signs every webhook with an HMAC-SHA256 hash of the request body in the X-Hub-Signature-256 header, made with the secret you set on the webhook. Add the secret to the recipe in Studio and JustPush checks every request before your code runs, so requests that don't come from GitHub never reach your phone.
