Connecting QuickBooks Online to Power BI via API (OAuth2) - Issue with Refreshing Access Token

Hello everyone,

I am attempting to connect QuickBooks Online to Power BI using the API with OAuth2 authentication. I have tried several methods to get the data, including:

• Power BI Web connector
• QuickBooks connector
• Custom connector (this was quite challenging to build, so I might have made some mistakes)
• Python script

Out of these methods, the Python script has been the most successful. However, I'm facing an issue where I need to manually change the access token every time I want to refresh the data.

I've created a function to fetch a new access token, but when I replace the static access token with this function in my data script, it doesn't work. I have also tried implementing this solution in the Web connector, but without any success.

Has anyone encountered a similar issue or could provide guidance on how to automate the access token refresh process within Power BI? Any help or suggestions would be greatly appreciated.

Thank you!
