Power BI and Marketo Connection Error

[Maria_FTGP]

Hi there i am trying to use the API connector from Marketo into Power  BI and failing at the first hurdle. 

I set up using the Endpoint, Client ID, and Client Secret. 

However i get the following error messages: any ideas what i can do?

Are you able to see what the error code is in the Detail=[List]?

It could be that the user you are trying to connect with hasn't got the correct API access. https://nation.marketo.com/t5/knowledgebase/rest-api-call-is-returning-603-error/ta-p/249694

Hi Adrian

no i cant see the Detail=List, at least i dont know how to see it... the API access in Marketo i cant see to edit or look at on the Marketo side either... comes up with other messages such as 

You cannot edit an API user that is being used in API service

so not sure what the deal is 😞
