Hi all,  
I’m new with the Hubspot Integration Development. I’m currently trying to integrate our call center with Hubspot and I stumble upon this [GitHub - HubSpot/calling-extensions-sdk: A JavaScript SDK for integrating calling apps into HubSpot. · GitHub](https://github.com/HubSpot/calling-extensions-sdk). It seems that I have to register for the "

Private Calling Extensions SDK beta

" [here](https://developers.hubspot.com/calling-extensions-sdk)

But currently, I can’t seem to submit my form. Can you give me some pointers on the registering process? And also any further information on the SDK would be a big help.  
Thanks,

Tien

Hi @cbarley, when I hit “submit” on the form, nothing happened (no error but no confirmation). Hope you can help me on this. Thank you

Hi , i’ve successfully submitted the form. Thanks for your help. It turns out that I have to push the submit button multiple times for it to work.

Hi, have any of you tried to restablish communication with the sdk after re loading the widget? I am reloading the iFrame, and the communication is lost but it does not try to do the ACK handshaking again. Thanks a lot!
