Hi @MarijeSchillern , referred the above article and documentations. These didn't help with what we wanted to achieve.
To give you an example, in R-U-F pxSendEmail, there are Pega Private Java APIs which refers the Email Account instance and sends an email using a Private Java API. There isn't an option available to configure Graph API custom end-points.
This can be though as using a proxy or facade instead of public Azure Graph APIs.
