https://developer.copper.com/leads/overview.html has the API for leads.
However… it does not allow merging two leads (e.g. duplicates)
Looking at the network trace from the web UI, I can see we do a POST to
https://app.copper.com/api/v1/companies/#####/leads_api/merge'
where ###### is my company-id (e.g. my copper account id), and in the body:
{"ids":[ID1,ID2],"conflicts":{field: value, ...}
Is this correct? How come it is not exposed in the documented API?
