hi
i thank you for your answer and your patience but i see here :
Another interesting call in our test .json collection from this guide is:
Action: Change layout
You’ll need displayGroupId and layoutId
You can call GET Displays to get displayGroupId - each display has it’s own unique displayGroupId
it’s what i did i made the get displays api call to have the displaygroupid
because i didn’t create any displaygroup
in a post you talk about hidden displaygroupid i didn’t understand what you mean
i think i follow the guide in a right way but the layout don’t change
thanks for your patience
