3rd party creating an API into our Pipedrive has 2 questions I can't answer, please help!!



A third party setting up an API to push records to us has asked me for two things which I can't find where to get. He has asked me the following:

A) I don’t see the posting url, in other words the endpoint where we post leads -

Where can I obtain that info please?

B) Regarding the parameters, or variables, for each record, we need the exact format used in Pipedrive, I’ve searched online and they may use something like @@phone@@ or possibly #phone# (as examples for the Phone variable). 

Does anyone know this please?

Thanks very much
