Hi gurus,
i'm looking for a way to get account details from a shared contact folder to make it available to a third party application.
In the REST API documentation i found:

that returns any contacts that has MYQUERY in any field.
So, if MYQUERY is "First Name" in one contact and "Address" in a second contact, i get 2 results.

I need to know if there is a way to insert "First Name" in the query to get only contacts that have MYQUERY in "Firts Name" field.

Any idea?
