Updating current app from API 1.0 to API 2.0

Updating current app from API 1.0 to API 2.0

Hi there,

My previous app was in c# and using API 1.0.

How can I update my app to use API 2.0. I see that you only provide SDKs for 4 languages  PHP, Java, Phyton and NodeJS.

Can you recommend the workaround for me to update my current app to use API 2.0?
