Button automation for cover change ends with 401 invalid key

[petra_vysusilova]

Hello, I am trying to set automation of button type for changing cover color (grey for wait button, yellow for inprogress button etc...). I have generated API key and token via power-up admin, but i always obtain 401 invalid key error. I tried public and secret key. What can be wrong? Thank you

@petra_vysusilova it might be telling you that you're unauthorized because Trello doesn't always like to "write" via that post/put action in automation. I'd try doing a get on the card data and seeing if you can return that info with the credentials and if that's the case then the 401 might be because Trello doesn't want you writing with it. 

If that's the case, I think you could make something with PixieBrix that would do this. (If you need any help trying that out, let me know — i work there and have been building stuff with it for a while. That's actually how I discovered it - by building advanced automations for Trello.)
