Patch/ Post method in Java

Hey Guys,

Can I get some resources on how to do Patch and Post operations in Java for Rest Api calls in ORO Crm?
I am using retrofit jar and both Patch as well as Post method is working fine in the sandbox but when I am trying to do the same in Java it’s throwing Bad Request Error. Steps I am following to carry out the Patch/ Post method on ORO Entity..

1. Generating X-WSSE authorization.
2. Setting Content-Type as “application/vnd.api+json”.
3. Sending the Body part as String.
4. The target endPoint URL is like localhost/api/{entity}.

Please refer below for the Patch method I am trying to execute:

RequestBody requestBody = RequestBody.create(MediaType.parse(“application/vnd.api+json”), msg);
Call<List<OroClient.OroContacts>> call = client.updateContact(id, requestBody);


@Headers({
“Accept: application/vnd.api+json”,
“Content-Type: application/vnd.api+json”
})
@PATCH(“api/contacts/{id}?format=json”)
Call<List<OroContacts>> updateContact(@Path(“id”) String id, @Body RequestBody requestBody);

msg is the string variable containing the Body part. Its like:

{“data”:{“type”:”contacts”,”id”:”3″,”attributes”:{“middleName”:”FSP”}}}

Id id the id of the contact I have to update.

Please note the same is working fine in api/doc as well as in the Rest Client.
