I'm using Developer Edition in which I coud see conver option for leads. I want to convert the leads to contacts/accounts using REST api.
How to accomlish this in REST api.

I have a custom object "Service Agreement". I need a button on the opportunity page to create a new "Service Agreement". This seems like it should be pretty simple, but I am not having any success (possibly due to my lack of experience with coding).
