Hi @Ashar_Shaikh, welcome to the community!
The maximum timeout is 3 minutes for the Start plan, 5 minutes for the Pro plan and 10 minutes for the Power plan. This means that n8n cloud is unfortunately not suitable for workflows that run for up to an hour, as in your case.
So you’d probably want to look at n8n hosting yourself here.
Edit 18 Dec 2023: The timeout values have changed since this was posted. They’re now 5 mins on the Starter plan and 40 mins on the Pro plans. You can also find this information on our pricing page which will be updated when things change:
Thanks so much to @Giovanni_Segar for pointing this out!
