There is currently a 5 minutes delay on the API call to remotely Schedule a Campaign.
This is adding more time for our application users to have the ability to test out their Email.
Would love to see this buffer removed or at least reduced if at all possible.
Are you currently not setting up the runAt time and letting Marketo decide for you (default is definitely 5 minutes)? Perhaps you can allow a user to set this up via an input and then pass it into your code.
