Trello API - Update Cards on Multiple Boards - What is the Key and Token?

[mydeqtechteam]

Hi, 

I have a program to update cards on multiple boards using the Trello API. I have tested and it works on a couple of boards that I have access on (using my developer API Key and Token). I now need to update the cards on Boards that I directly do not have access on (private boards in my Organization). How do I generate the Key / Token to be able to do this ?

@mydeqtechteam are you doing this from a power up? If so you just need to get the user to authenticate:

Permissions in the API are governed by the token  you pass in, and each API key can have multiple tokens authenticated against it.

Thanks for the response @Iain Dooley Is it possible to generate a token per board ? This will enable my Developer Key to only update certain boards. How would I be able to do that? The above API is not for a Power-up but integrating Trello with an external system.

@Udai Inuganti not that I'm aware of, you can only use read or write in the scope parameter, and you can't specify that a given token has access only to a subset of boards within the authorising account.

That's my experience and I can't find any documentation to the contrary, but you might also like to ask in the developer community:
