Answer: Take a deeper look at the request #payload going to the API or a #Web Service, inspect the headers and you will find that the #ContentType is truncated. This can be an issue with the specific Http Client library you are using.

If you are using #RestSharp to call a remote API in C-Sharp, make sure that you pass in the #Payload through the Body. See the code below:

//Avoid the code below 
request.AddParameter("ParameterName", Payload, ParameterType.RequestBody);

//Recommended code below
request.AddBody(Payload, contentType: "application/json");
