Studio password protection, auto updates and further reduced developer dependency

Studio password protection

Connection settings and access to the chat flows is now password protected. Password has to be set for the first time, which encrypts your settings file and also prevents access to the studio.

Reduced developer dependency

When using APIs in the chat flow, the behavior of the flow(which node to go next) can now be directly manipulated from the API's response without any wrapper on top. Client(Simulator) has the capability to parse the API's JSON response and match the value of the specified key with the one provided to change the course of the flow.
