How to send Parameters through Body with body type - multipart/form-data in HTTP Request

Hello Kiran,
I use VB.NET code for MULTIPART/form-data because I don’t find other solutions to use it with HTTP Request Activity.
All the code is Here:
startUiPathFromSalesforce/FormData.txt at master · cristinegulescu/startUiPathFromSalesforce · GitHub
In my case, I upload files and parameters that’s why I use multipart/form-data in your case I don’t see that you need this.
Take a look at this thread on their solution:
https://community.powerbi.com/t5/Desktop/Azure-HTTP-POST-requests-for-an-access-token-from-Power-BI-power/td-p/968625
It looks that’s is working for all application/json witch is normal.
Thanks
Cristian Negulescu
