The best CRM with a simple and popular API?

Question

CRM

I've been tormented with Bitrix24, I need CRM to create leads and interact with them through the API. It is desirable that the API provides all the functionality of the web version. Or do I not understand something and Bitrix24 is not so terrible?

Answer 1

Bitrix24 is not so terrible, but still with a pinch of horror)
As an option - Megaplan.
You can also try Bipium, Pipedrive, but these are unpopular services in Runet.
