I also worked on a Python project that integrated DocuSign.

I was able to hack together solutions and skirt around DocuSign's many problems, garbage documentation, and general very-low-quality API, but in no circumstance would I ever recommend it to anyone. Late in the project I seriously considered throwing it away and switching to another API.

The other API I considered was: https://app.hellosign.com/api/pricing

This is literally ten times the price of DocuSign and I don't know how long they'll be in business, so it's a hard sell to buy into that. The API docs looked way way better (like stripe or twilio or slack apis, rather than some janky enterprise nonsense), but development and hacking around DocuSign was a one time expense, and the API is an ongoing cost.

If remotely possible, I'd just sign stuff in person and mail or fax it, since all this stuff just adds difficulty, complexity, and cost, to very little benefit unless you have a LOT of people signing stuff. The application I worked one was for one or two signatures a month, so not worth the trouble.
