We are excited to announce that our API playground got a complete makeover! 
This update has been years in the making, and it is finally here! The playground has a brand new, intuitive UI that provides an overall better user experience. We’ve shifted some of the buttons to reduce clutter and maximize platform real estate. We’ve also added tabs that allow you to run multiple sessions at once, history tracking that allows you to add specific calls to your favorites, and HTTP header support.
Currently, you can only access the new API playground through the Developer’s Center, but we plan to update the public playground in the next few weeks.
Check it out for yourself and have fun exploring all of the new features!
