How do you unlock ifttt?

good morning
ever since i activated cloudflare i have noticed that ifttt is no longer working for me. What does it depend on and how to solve it?
Thank you

You probably want to check your WAF logs to see if your requests are being blocked by some of the built-in security rules. You can check the logs here:

You can then make a new WAF rule that skips common items you found the blocked requests.
