How to be able to work with the API of Tropo and Smartsheet?
BlockSpring don’t have yet the interface and Zapier too.
But I just read this from Bubble:
Another exciting thing Blockspring offers is the ability to write your own blocks. You can write a few lines of code in a language of your choice (they currently offer Python, Ruby, Node, PHP, and R), and Blockspring instantly converts it into an API for you, including automatically hosting it on its cloud.
