Looping Httprequest for each item in Array

[Bhuvi]

Hi Team,
Thanks for such wonderful tool.

Here is my use case. i will be receiving array of item from webhook response, then i want to make a http request for each item in the array and need to consolidate the response of all http request into single response object. Kindly confirm is it possible with n8n available nodes?

How to set timeout to each loop? and how to continue looping if code is not 2XX?
I was checking response code for 140+ urls to find out 404 websites. But continually got
“Error: unable to verify the first certificate”

here is my workflow

Hey @liqt91!

Welcome to the community

You can refer to these post to learn how to add a timeout:

Wait node in workflow [GOT CREATED]

Totally agree! A wait-node would be very important for many use cases. Implementing that properly is sadly not trivial and would take some time. For a short wait time (a few seconds) it would be OK (and best) to simply leave the process running. That can also be done with a Function-Node already like this: For everything longer, it gets more complicated. Then it should save the data of the current workflow to the database, set up some kind of timer in the main process (…

Loop x times when IF is false

Edited the Question with better clarity. @jan @RicardoE105 @harshil1712

To continue the workflow and ignore the errors you can set the Continue on Fail option to true. In the node, go to the Settings tab and toggle the option to true.
