Hi,

I have an issue with writing a string to Talkback (returnng 401 code).
TalkBack ID: 123456
Command ID: 789011
Designer view:
web1 url = https://api.thingspeak.com/talkbacks/123456/commands/789011.json

Blocks view:
Call web1.PutText = api_key=AAAAAABBBBBCCCC&command_string=Open&position=2

What am I missing ?

Regards,
Mb

Try with GET or POST ?

Hi Tim,

That's true POST and GET can be use.
TalkBack ID: 12345
api_key=AAAABBBBBCCCCC
command_string = OPEN
From Thingspeak documentation:

POST https://api.thingspeak.com/talkbacks/12345/commands.json
api_key=AAAABBBBBCCCCC

Now how do you set that into an APP inventor.

That's where I'm struggling.

You use the web component to build the url

Hi Tim,

I've manage to had it working :wink: I guess I needed to excange on the topic.
What I have found is that :
web1.PutText let you write/update to a talkback position.
web1.PostText let you add a talkback command at the end of the other comand.

Many thanks !

Kind regards,
Mb
