Call an integration services in a!gridColumn

You can use the Record action component - Record Action Component within the grid column to call a related action in context of that particular record.

Sample code snippet -

  a!gridColumn(
    label: "",
    sortField: <recordColumnSortField>,
    value: a!recordActionField(
        actions: {
          a!recordActionItem(
            action: <recordRelatedAction>, /*Use record! e.g. recordType!Case.actions.editCase*/
            identifier: <recordIdentifier>
          )
        },
        style: "TOOLBAR",
        display: "ICON"
    ),
    align: "CENTER"
  ) 

thank u for the reply. this works. 
i have another problem that i can try to resolve.

Is this in the modal after clicking the above described recordActionItem? What are you setting for the "identifier: <recordIdentifier>"? Are you passing a valid record id specific to the row? 

it should probably look something like this:

I got this thanks to your reply; i wrote

recordType!<RECORD_TYPE>.fields.<identifier> but is incorrect.

the right version is

fv!row[recordType!<RECORD_TYPE>.fields.<identifier>]

I have only one last question; it is possible that when you click on the column where the recordActionField is present, you do not open a new tab but show a modal with a message that the action has been performed successfully

You can set the Open Action In property,  openActionsIn: "DIALOG"

and on the related action details in the record you can set the size of the modal too.

thank u for the support Dave. 

I incorporated the list of record types inside an interface, inside a read-only-grid component; but, when I click on the "related action" button, I have the same permissions problem:
