In our marketing cloud instance, we are having 2 BU.
When we are executing triggered send from new BU via REST API, we are getting error : 404 API not found
even though all triggered send definitions etc are present in this new BU. This probably is due to the fact that access token for this new BU should be different from original BU's access token. And to generate this new access token, we require clientID and clientSecret of this new BU.
So how do we get new access token/clientID/ClientSecret for new BU? I assume these would be different for different BUs.
We have an installed package for old/main/parent BU with API Integration type of component in it that has its clientId and clientSecret. When we click on "New" in this package to create a new API Integration component, it does not let me select that again, implying we can have only 1 API INt. per package.
So for the new/child BU, how do we use this API Integration component, or how do we create a new API Integration component? Do we need to install a new package for new BU and if yes how to do that?
