Hi @Amerehei,
We understand the need for interactive buttons, and this feature is currently in our backlog and we will announce once we have a timeline. We do, however, currently have subscription events, that can be accessed via our graphQL subscriptions (which require a socket connection) but we don’t currently have an event for element onClick. There are a number of events you can subscribe to including adding a comment to an element, creating/updating/moving an element, etc.
Regarding pan/zoom with API: our APIs are not designed to move the viewport in a window for zoom/scale. These are handled by the user in our client only by design. Our APIs are used for querying elements in a workspace, creating/updating elements in a workspace, or listening to subscription events in a workspace to know if a user moves an element, or updates and element, etc.
Can you clarify exactly what you are looking to accomplish and we can see if there is a solution with our current APIs that could work for you?
