Fusion:: How to check status of proof stage 1 and delete proof stage 2 if proof approved in stage 1

[AutomaSean]

Hello,

I have an automated proof workflow that contains 2 stages. Stage 2's purpose is to escalate the proofing to leadership if Stage 1 doesn't complete in time. I want to delete Stage 2 when Stage 1 completes. I assume I need to utilize a custom API call to Workfront Proof, but I can't find any good examples that show me the proper way to set up the module, etc. 

Thanks for any help!
