@thalissonm I am having the same problem here. I facing problems with the leads route. When i try to send a post to /leads, it says method not allowed. I found an issue on github about send post to leads route and they sayed to use leads/leads instead. I try that. But got a 404 response. My first impressions is that they abbandonned the project. There is no response here on the forums and the documentation does not help mutch. For exemple, I am using nginx as a webserver but there is nothing on Dev Docs about nginx configurations. Krayin CRM sounds very promising, but unfortunately WebKul hasn't done anything to grow the community. They don't try to resolve bugs or provide assistance to developers who want to contribute to the project.
It is a shame.
