I have a HTTP call from a ESP8266 it worked with V1.x  
In the IDE Arduino envoronment it is composed as follows:

http.begin(“[http://192.168.178.18/api/app/com.internet/OntvangenGETTemp0/](http://192.168.178.18/api/app/com.internet/OntvangenGETTemp0/)”+String(temp0)); (temp0 is the variable to be passed to Homey - BetterLogic- variable!!)

im Homey V2.0 i now get this error:  
{“code”:401,“error”:“not\_logged\_in”,“error\_description”:“You need to log in to access this resource”}

Can anybody help me with the cards/parameters t use in V2.0 !!!

In the settings for the HTTP Request Flow Cards app, you need to disable authorization if you want it to work on v2. Look at [this post](https://community.homey.app/t/tutorial-using-siri-shortcuts-for-activating-flows-with-pics/7473), from point 6 onwards.
