Hey @robin m Racheal from the support engineer team here👋
At the moment, Intercom does not have a webhook for conversation data attribute updates. But I definitely understand how beneficial this would be to have, I would love to pass this along as a feature request for the product team. This is a great idea for the @Product Wishlist !
Perhaps a workaround could be subscribing to conversation.user.replied and conversation.admin.replied and then retrieving the conversation details from the API. I understand this would not be as automatic and simple as a webhook that was triggered every time a conversation detail was updated, so I will +1 this request on your behalf.
