Have you made your condition a Trigger to fire a Logicblock (this is a “lightning” tick box in the Condition setup) and send your event to IFTTT?
Have you added a New IFTTT event to your Logicblock positive action chain and named it something relevant to your IFTTT action?
Have you then added a Receive an Event from Apilio applet in IFTTT? You should see the event name you added in step 2 in the IFTTT dropdown.
If you’ve done all of these things then when the condition is reached it will trigger the Logicblock evaluation to send your new Apilio event name to IFTTT.
Hope that helps but let me know if you need any more support. DanT
