Integromat always running

So I completed the telegram project but in the order for it to work, we have to run it once in integromat and then leave it running. I was just wondering is it ok means can we just leave it running forever.

Of course yes. You can keep it running forever, but you may want to keep an eye on the operations being used, as with the regular plan, there is a limit of 1000 operations per month.
