Getting a 406 - Unable to resolve Accept header to a representation on Rest request

[InekeBauw]

I receive a 406 - Not acceptable

RAW request :

Content-Type: application/json
Content-Length: 0
Host: api.********.com
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.2 (Java/1.8.0_162)

In Postman everything works fine.

Hi Ineke,

Thank you for your post! Try to add the Accept header with the */* value as it's shown on the following screenshot:

Also, I can recommend comparing a successful (or expected) raw request with a raw request from ReadyAPI. 

To get a raw request in ReadyAPI, please switch to the Raw tab on the left side of the Request Editor.

To get a Raw request in Postman http://screencast.com/t/LpyQIAIH, click the Code button and choose HTTP: http://screencast.com/t/SLEdPUNX

Or, you can use Fiddler (http://www.telerik.com/download/fiddler) which is a free tool to capture HTTP(S) traffic.
