Hi all,  
I’m new with the Hubspot Integration Development. I’m currently trying to integrate some third party call center with Hubspot and I stuck in this [GitHub - HubSpot/calling-extensions-sdk: A JavaScript SDK for integrating calling apps into HubSpot. · GitHub](https://github.com/HubSpot/calling-extensions-sdk).

I did the following step.

1. Install the Hubspot Calling extension SDK with node.

2. Run this

```auto
// Add the following localstorage override for demo widget
localStorage.setItem(
 "LocalSettings:Sales:CallingExtensions",
 '{"name": "Demo widget", "url": "https://localhost:9025/"}'
);

```

I need help with this, can anyone help ???

Thanks,

Hi @shubham291994 ,

Are you still facing an issue with this?

Are these the instructions that are detailed with the 3rd party app that you have listed?

Can you detail more specifically what you are having issues with?

Hope all is well!

Hello Dennis,

I have integrated HubSpot calling extension successfully, but the client ask me to add one more feature to it, they ask me to pass the caller detail to the API. I don’t know how to fetch Caller detail or contact owner id. Can you please help ??

Thanks,
