A single endpoint to convert a lead to a deal would be really nice. I saw another post with the recommended solution of 3 calls (get id, create deal, delete lead), but that feels like a lot of work, especially when the action (convert to deal) is inherent to the UI.
Thanks for the valid feedback @briiian@dzisner I have forwarded the feedback to the concerned team. Please stay tuned to the announcement section. I will update once it is public & added to the docs.
