Hi @Rose_Languste !
Yes, the service is working in general and we see a lot of successful requests in the IFTTT logs every day.
If you PM me your Applet version ID I can check for you what information we get on that from IFTTT for the last 48 hours to hopefully figure out your issue. I assume you already checked with our customer support that the Nuki Web setup (correct activity log entry tracking there is needed for IFTTT) is correctly working?
