Send app reviews to Slack and Discord

• Google Play: Play Console emails you about new and updated reviews.
• App Store: the only review email Apple lists is for when a customer edits a review you've already answered. A new review reaches you only as a notification in the App Store Connect app for iPhone and iPad.
• The App Store Connect API's webhooks don't include a review event either, so a job has to ask the API for new reviews on a schedule.

1. 1Create a Slack app and pick the workspace it belongs to.
2. 2In the app's settings, open Incoming Webhooks and turn on Activate Incoming Webhooks.
3. 3Click Add New Webhook to Workspace, choose the channel and click Authorize. For a private channel, join it first.
4. 4Copy the webhook URL. Posting a message is a POST of JSON to that URL:

POST https://hooks.slack.com/services/T…/B…/…
Content-Type: application/json

{ "text": "1★ Nook Focus · App Store · USA\nThe timer stops when I lock my phone." }

Each webhook posts to one channel, and a message can't be deleted once it's posted. The URL contains a secret: keep it out of your code repository, because Slack looks for leaked webhook URLs and revokes them.

Create a webhook for the channel in Discord and copy its URL. Posting needs no bot and no sign-in: a POST /webhooks/{webhook.id}/{webhook.token} with content (up to 2,000 characters) or up to 10 embeds is enough.

POST /webhooks/{webhook.id}/{webhook.token}
Content-Type: application/json

{ "content": "1★ Nook Focus · Google Play\nThe timer stops when I lock my phone." }

That's also why the URL must stay private: anyone who has it can post to your channel.

• App Store: GET /v1/apps/{id}/customerReviews?sort=-createdDate returns the newest reviews first, up to 200 a page. Remember the newest date you've posted and stop when you reach it.
• Google Play: GET …/applications/{packageName}/reviews returns only reviews written or changed in the last 7 days, and each app gets 200 read requests an hour. Checking every few hours stays well inside both.
• Each store needs its own access: an App Store Connect API key, which an Admin creates, and a service account with the Reply to reviews permission on Google Play.

• The star rating, the app, the store and the country, so the right person picks it up.
• The review in full. For a translated Google Play review, the API also gives you originalText, the reviewer's own words.
• The app version the reviewer had, which Google Play's API includes when it knows it.
• Lowest ratings and reports of a technical problem first: that's where Apple suggests starting when you can't answer every review.
• Several reviews in one message rather than one message each, so the channel stays readable.

Merci AI checks the App Store and Google Play for new reviews every 6 hours and posts them to your Slack or Discord channel, the most urgent first, with reply drafts in the reviewers' languages and links back to Merci AI. You can get the same alert by email. Nothing is published to a store until you click Publish in Merci AI, and the webhook URL is stored encrypted.
