You do this:
That sets the method to POST. The 'X-HTTP-Method-Override' is just a header. It's a common pattern but not one the REST API recognizes. Instead, you can add '_HttpMethod=PATCH' to your endpoint as a URL parameter:
yes I discovered this earlier and got it working. I couldn't find anywhere that this was documented but came across it in a forum post elsewhere.
For anyone else who suffered the same frustrations, here is the code:
public async Task<int> addMyOrderToExistingContract(){
string serviceURL3 = "https://mydomain.my.salesforce.com/services/data/v39.0/commerce/sale/" + contractid + "?_HttpMethod=PATCH";
Salesforce.Force.ForceClient myforceclient1 = new ForceClient(serviceURL3, accesstoken, "v39.0");
HttpClient queryClient3 = new HttpClient();
string insertPacket = "";
insertPacket += "{";
insertPacket += "\"contract\": [";
..build your json
StringContent insertstring = new StringContent(insertPacket, Encoding.UTF8, "application/json");
HttpContent content = new StringContent(insertPacket, Encoding.UTF8, "application/json");
HttpRequestMessage request3 = new HttpRequestMessage(HttpMethod.Post, serviceURL3);
request3.Headers.Add("Authorization", "OAuth " + accesstoken);
request3.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
request3.Headers.Add("X-HTTP-Method-Override", "PATCH"); //PROB DONT NEED THIS
request3.Content = insertstring;
HttpResponseMessage response3 = await queryClient3.SendAsync(request3).ConfigureAwait(continueOnCapturedContext: false);
string result33 = response3.Content.ReadAsStringAsync().Result;
return result33.Length;
}
//call the above
int testint = addMyOrderToExistingContract().Result;
It's referenced in the REST API docs but it's a bit hidden: https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/dome_update_fields.htm
The very last paragraph on the page describes it.
For your example code: you're right that you don't need this line:
request3.Headers.Add("X-HTTP-Method-Override", "PATCH"); //PROB DONT NEED THISsince Salesforce doesn't do anything with it.
