I was able to create LEAD using Dynamics CRM API. and it is great.
Now I also want to create CONTACT record after LEAD is created and create Parent to child relationship. E.g.
I have a web form and ask for father full name and I will add father full name into LEAD entity (1 records)
2nd step, I have a web form and ask for how many kids, if 2 then, two kid full name will be created into CONTACT entity (2 records)
On Dynamics, what Do i need to do to make LEAD/CONTACT has relationship inside of the database?
