In my company's Email Marketing Cloud Account we have multiple accounts (that is business Units). In our earlier integration with SOAP API we were able access the objects in these business units through the API by providing an API User username and password.
But now we are trying to switch to use the FuelSDK-Python, we noticed that the clientId and clientSecret only lets you access a single account (one business Unit), which means we have to create clientId and clientSecret for each of our business Units. For us this isn't scalable because we have a lot of business Units and most times in a single request we are interacting with more than one.
So my question is, is there a way to integrate all of our business units with a single clientId and clientSecret, or with an API User username and password just like with the SOAP API
And I forgot to mention these business units are hierarchical in nature, so we have one top parent and then tree grows from there.
