Hi,  
I am new to hubspot and i try to trigger a webhook, when a contact is edited.  
As it looks, this is only possible using a developer account. So I created an dev account and also the webhooks.

The events are active. But nothing happens when a property is changed.  
What did I forget?  
Thanks  
Holger

Hey, @Dixus 👋 Thanks for reaching out. To confirm, in addition to what you listed above, you’ve:

- Set up OAuth for your app
- Installed your app in an App Test Account or in a Production portal you are working or testing with?
- Can you make a request to this endpoint and return the expected subscriptions? — [GET Subscriptions](https://developers.hubspot.com/docs/api/webhooks#get-subscriptions)  
`GET /webhooks/v3/{appId}/subscriptions​`

Thank you for the additional information! — Jaycee

Tank you. We found a solution. But it took a long time because it is not documented well, how to implement the callback site (and that you have to host a local webserver to get it working).
