Compare two object arrays by specific key and save non-duplicates

[dgonzalesjr]

I've created two object arrays. I would like to compare the two array items by 'SpaceId' key, then add whatever items don't match to a third array. Here is a sample of my two arrays:

I would like my condition to be if variable(array1)['SpaceId'] is not equal to variable(array2)['SpaceId'] then append to a 3rd array.

If they are equal then do nothing.

I'm pretty sure my syntax is probably totally off but I hope I'm getting my goal across. I'm new to the game so I would appreciate any help that I can get with this.

Here is how you can do it...

Compose2 Expression --> item()?['spaceid']

Filerarray expression --> item()?['spaceid']

Check Length expression -->length( body('Filter_array'))

Finally append to array expression --> body('Filter_array')[0]
