Business Central Adobe Reader API Integration

Dynamics2018

Hello,

I am working on Business Central Adobe Reader API Integration. I am struggling with passing MediaType in Request via programming.

I have followed Adobe Reader API Documentation and passing MediaType as per given example. But I am getting error when Request is sent via programming. The same works when I send Request using PostMan extension in visual studio code.

Snapshot 1 and 2 give information about Adobe Reader API Documentation.

Snapshot 3 and 4 give information about programming to send request and error that I am getting.

Snapshot 5 and 6 give information about sending request from PostMan and its response.

Any help or suggestion is appreciated.
