Known specifics

Lead conversion: Bitrix24 REST has no dedicated conversion method. To "convert" a lead, create a deal/contact/company with leadId and update the lead status:

javascript 
// 1. Create a deal from the lead
await fetch('/v1/deals', { body: { title: 'From lead', leadId: 5001 } })
// 2. Close the lead
await fetch('/v1/leads/5001', { method: 'PATCH', body: { statusId: 'CONVERTED' } })
