Problem with POST method in ODATA API


I have a problem regarding to POST method in ODATA service

I need to use one of the following POST/PUT/PATCH method in order to change a parameter (name of Ticket) or create new entity for Service request(Ticket)

This is my JSON format:

But when i Execute it, I recieve this message:

Uknown error. Please check the metadata and try again!

Could anyone help me how should be the format of POST or PUT?

I have tried in so many different ways and I am totally blocked :(

    Hi S Sin,

    You may use only PATCH to update an object, I had some issues using PUT.

    Anyway, you does not need to pass the metadata in the payload of your request. Moreover, the url cannot be $?filter=ID eq '2' this must be replaced by the UUID, just like is in the uri of your payload ('00163E03A0101ED28A8644CF8D83AE76').

    Something like this:

    Method: PATCH
    Payload: JSON
    "d" : {
    	"ID" : "id of Object",
    	"Name": "Name of Object"

    Best regards,

      "type": "cust.ServiceRequest",
      "etag": "W/\"datetimeoffset'2012-11-06T16%3A51%3A55.1323330Z'\"",
      "Payload": "JSON" },
