Extract custom fields using API from two datasets and integrating them together


Hi I am trying to represent a common table filled with the data of two datasets “contacts” and “deals” by integrating the two datasets. The problem is there is no field that is common between the two datasets.

Also can I extract custom fields from the two datasets using API.

I’ve also tried to use datahero.com but it only allows me to make a chart with three text fields .

Kindly provide a solution to this problem.
