Blynk legacy api doesn't work

I can’t use the blynk legacy api with my token for some reason. It always says that I use an invalid token (400 bad request) although I use a valid one.

The token can’t really be invalid cuz the app works so I guess it is valid. I also tried a new token but that didn’t work either.
Can someone please help me ?

Hey there,

Use this url ( ) and make sure to replace with blynk server IP address.

what’s the ip of the blynk server tho ? I don’t use my own server or does the API only work with an own server ?

thank you!

Does it work ?

In your screenshot, you seem to be using a URL that contains the Auth token (which is the correct way to do it) then specifying a different token in the tool that you are using.
