Hi, I can happily connect and read data using the standard ServiceM8 API but when I try to connect custom fields API with Microsoft Power BI ([https://api.servicem8.com/custom\_fields\_1.0](https://api.servicem8.com/custom_fields_1.0)), I am getting told I am not authorize.

Can anyone please assist me with connecting Custom Fields API to Power BI. Thank you
