Remove Duplicate Array Value

Original post is here.

I have picked up the latest connector information of Flow everyday by LogicApps, but since the newly added connector "2 times" has appeared this time, it was always an error when doing the second tweet. I found duplicate values in the created array, so I tried how to eliminate duplicate values from the array in LogicFlow.

In conclusion, we will use the union function.

The union function is a function to merge union (Array 1, Array 2, ...) and the specified array, but at this time it eliminates duplication. This function is used to eliminate duplicate values in an array.

Create a LogicFlow like the sample above. First define the array variable and make it have a duplicate value with createarray function.

Next, use the union function to specify that you want to merge themselves.

Then, it eliminates duplicate values as described above.

When creating various kinds of processing, the place of operation of the array is often confused, but it seems likely to be able to deal with it in a surprisingly simple way.
