Although the create and update dates of "operation_to_contact" were null, which was the association we intended to use.</P><P>I tried manually creating the association between one instance of each object, throught the API with no success.</P><P>The end-goal would be to create these custom-objects through one WorkFlow and associate it to a contact.<BR />I'll keep studiying the Custom Objects API, i might've left something pass.</P><P>If you have any tip, Lemme know!&nbsp;</P><P>&nbsp;</P><P>Lucca P S Deluqui</P> Fri, 29 Jan 2021 13:54:59 GMT Lucca_Deluqui 2021-01-29T13:54:59Z
