Thank you for your reply Krileon but not so helpful for me that i am not a programmer!
So let me put things in an order so that i can understand what to do...
Created type Code auto action. Triggers: activity_onDisplayActivity, User: Automatic, Access Everybody.
Conditions... Field: Value, Custom Value: [var3_isRow], Operator: Equal To, Value: 1.
Now regarding your blog post, you mention...
Simply add &format=jsonapi to the auto action URL
Where do i have to add it? Somewhere inside the above Code Auto Action? Where is the Auto Action URL?
Thank you.
