**Hi Support,**

I just created App in my developer account, but the thing is app webhook is not working, I mean **JSON payload request**

is not sending to my [webhook URL. Please share any document or Video on creating a developer App.](https://5bc4fe94.ngrok.io)

and

If it possible please share any document (or video) on deploying my app to the marketplace and condition of the app to get deployed to Hubspot app marketplace.

Hi, @Shivasagar.

It doesn’t look like app **202798** is installed anywhere. You will have to connect it to at least one account through [this OAuth flow](https://developers.hubspot.com/docs/methods/oauth2/oauth2-quickstart) before the webhook subscriptions will send you notifications.
