I am trying to update my entity from power apps flows. But i am not sure about the object id (Unique identifier of the object to update). I tried giving the primary key value of the entity and also with 'Recid' but no luck, can anyone help me on this what exaclty object id refers ?
If you would like to get the GUID wihtin Microsoft Flow, then first add a Get Records Action, then add a condition to fitler the records, after that, use the GUID from the fitlered record to perform the actions. Another way to get the proper GUID is through PowerApps, create an App using the correspondign entity, then find the proper record, unhide the GUID field under Display form, it should display the record GUID there.
