Hey @yellalingh,

When looking to retrieve your application id for a HubSpot app, you can refer to this detailed documentation - [How do I find the app ID for a HubSpot app?](https://developers.hubspot.com/docs/faq/how-do-i-find-the-app-id).

Hope this helps and do let me know if there’s any further questions on this!
