Step 3: Create your Yext App
Finally, you will have to create an app in your Yext account that will use the uploaded plugin file to trigger a Slack message every time you receive a new review.
Navigate to Developer > Developer Console.
Click Add an App in the top right corner.
Enter a name for your app (something like “Slack Reviews Publisher”) and click Create App.
Under API Credentials tab, add a new API Permission, with the endpoint Management API > Reviews and the permissions Read-only. Click Save.
Under the Webhooks tab, click Add a Webhook.
Under Webhook Type, select Reviews. Click Next.
Choose a name for your webhook, such as “Slack Review Notification”.
Under URL, click Invoke a Function. Choose slackReviewsPublisher and select the function handleNotification.
Keep the V Param as is, and click Finish and Add.
Now that the webhook is live, you should start receiving notifications in the Slack channel you specified!
