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,

This is my JSON file

{ "uri": "'00163E03A0701ED28A8644CF8D83AE76')",
"type": "cust.ServiceRequest",
"etag": "W/\"datetimeoffset'2012-11-06T16%3A51%3A55.1323330Z'\"",
"Payload": "JSON" },
"Name": "ChangedName",
"ETag": "/Date(1352220715132)/",
"ObjectID": "00163E03A0701ED28A8644CF8D83AE76" }
