I have a a very simple Zap as I’m testing out the Looping function.

Step 2: I’m looking up a google sheet, and I’m going to be using COL D specifically.


Step 3: In the Loop using Line Items, you can see that I’m calling on Column D. Delimiter is the comma.


Then, when I test it, it seems to be working fine:


Step 4: I want to put the result into a cell on google sheets


The initial test seems to work properly, only going through the loop once.


Now, here’s the issue: When I publish the zap and run it, it seems to double up the responses.

Does anyone have an idea as to why this might be happening? Is this a Zapier bug with Loops?

Hi @luniko 

To help you troubleshoot, check your Zap Runs history details to see the DATA IN/OUT for each step:

I seemed to have figured it out.

There can be chrome extensions that cause the webhook to trigger twice. Chrome is my primary browser with various extensions. When I can the zap using Edge (which I don’t have any extensions for), it worked fine.
