Problem with POST method in ODATA API

[sinaei]

Hi,

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 😞

Regards
Sin

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
URL: https://myxxxxx.crm.ondemand.com/sap/byd/odata/cust/v1/custom_ticketodata/ServiceRequestColletion('UUID_of_Object')
Payload: JSON


"d" : {
	"ID" : "id of Object",
	"Name": "Name of Object"
}

Best regards,
