Merging arrays into one



I have two parallel Azure AD Get group users actions and I want to merge the result into one so I can then apply a for each to the combined array


How can I do that? Thanks

Re: Merging arrays into one

You might have to step through one array using the apply and then use array.add expression to add each item of the second array to the first array

Re: Merging arrays into one

Hi @ christian-aid,


I have made a test on my side, you could refer to steps below to create the flow:

  1. Add a trigger, here I use the “Manually trigger a flow”.
  2. Add an “Initialize variable”, name the variable as “group users”, the type choose “Array”, leave the “Value” field blank.
  3. Add action “Get group members”, fill in the first Group Id in the input field.
  4. Add an “Apply to each” under the “Get group members”, choose the “Group Members” dynamic content of the “Get group members” in the input field.
  5. Add an “Append to array variable” inside the “Apply to each”, choose the “group users” in the Name field, choose the “Current item” dynamic content of the “Apply to each” in the “Value” field.
  6. Add a parallel branch under the “Initialize variable”, add a “Get group members 2”, “Apply to each 2”, “Append to array variable 2” as step3,4,5.
  7. Add a Compose under the “Apply to each” and “Apply to each 2”, the expression of the Compose as below:

union(variables('group users'),variables('group users'))

Note:This step is to return only one element if there are the same elements in the array.

     8. Add an “Apply to each 3” under the “Compose”, choose the “output ” dynamic content of the Compose in the input field.

     9. You could add a “Compose 2” inside the “Apply to each 3”,choose the “Current item” dynamic content of the “Apply to each 3” in the input field to get every member’s information.




The flow would run successfully as below:
