Alternating pattern - router

How To

1

Hi all,

Let’s say this flow gets triggered 100 times a day. How can I ensure that half of the executions go through Route 1 and the other half through Route 2?

There are no specific filters—I just want a simple alternating pattern:

  • 1 goes through Route 1
  • 2 goes through Route 2
  • 3 goes through Route 1
  • 4 goes through Route 2
  • etc.

Thanks so much!

Welcome to the Make community!

To do this, you can try using the Tools “Increment function” module —

Returns a value of 1 after first run. Every subsequent run will increment the returned value by 1.

Don’t forget to check that it’s set to Never:

For more information, see https://www.make.com/en/integrations/util, and https://www.make.com/en/help/app/util in the help centre.

Then, you can use the modulo (mod) operator in the filter to check if the number is an odd or even number.
