Each Applet you enable on IFTTT has information about how quickly it runs. You can see this information by selecting an Applet from your list of enabled Applets. You'll see some text near the bottom that states [Type] Applets usually run within [Time]. This is based on the time it usually takes for Applets of the same type to run.
You also have the option to run the Applet manually via the Check now button on this screen.
Users on the IFTTT Pro plan benefit from prioritized Applet run times. If your Applets aren’t running as quickly as you'd expect, consider upgrading to IFTTT Pro.
Most service owners have tools available to them to make triggers realtime, we encourage you to reach out to them if you think this would benefit your Applets.
