Is there a webhook that can be triggered when someone sends money to a Cash App account? Using this to trigger a toast notification on my PC during twitch streams.
Unfortunately a webhook for Cash app events isn’t currently available. Please feel free to reach out if you have any additional questions. 
Webhooks for Payments allows you to receive real-time notifications whenever a payment status has changed .
Webhooks for Payments works a little differently than other Webhooks so please use the Webhooks for Payments docs when setting up this type of Webhook.
Webhooks are the user specified HTTP callbacks that get triggered by some event reactions and used to connect two applications. It’s a way to send response payload from Paytm server to a unique URL configured at Paytm’s end to notify the final status of transaction, refund, etc. Unlike an API, where you need to poll the data frequently to get the real time information, it lets you receive the automated, instant, real-time data from Paytm server to your server on occurence of a given event.
To consume a webhook, initially you must configure a URL at Paytm’s end that is accessible from the public web, the URL should be capable of handling the updated event/response sent by Paytm. It provides the mechanism to Paytm Payment gateway to notify your customer on the URL provided by them about an occurrence outside the flow.
Cash App is a mobile app-focused money transfer service . You can send and receive funds directly and quickly, like you could with PayPal or Venmo. But Cash App features a few other functions as well.
