I am having trouble creating a service reference in VS from outside my D365 dev box

The outside application currently interacts with D365 through OData using secrets and this works well. However when I tried to setup a service reference it's asking me for a user name and password. I have tried D365 admin users, tenant users, builtin admin login but it won't authenticate, what am I missing?

Have you checked the D365FO Integration Sample App? It has samples for custom services, too.

You can install, run and debug the app locally to see how it's implemented and how it behaves.

Hi richerich79,

You are trying to create a service reference for REST-based service, but it should be SOAP-based service.

If you want to consume REST-bases service from VS, check the documentation. It contains a reference to the example project as well.

Hi Sergei. I'm still banging my head against the wall with this.

I don't think this is a REST-based service. There is a wsdl at "myendpoint?wsdl" and looking at the service it extends SysOperationServiceBase and has DataContractAttribute and DataMemberAttribute on the model contract.

If I do treat it as a REST endpoint and put the model in the content of a http POST request I get the following error returned from the server

{
"Message": "An exception occured when deserializing a parameters - Exception occurred when parsing and deserializing parameter '_contract' - 'Parameter '_contract' is not found within the request content body.'",
"ExceptionType": "XppServicesDeserializationException",
"ActivityId": "e1eb8675-545e-0000-ca93-ebe15e54d601"
}

Im still in the position that I can't add the service reference

We can say that from the URL - you're using /api/services/ instead of /soap/services/.

The exception is saying that you're sending wrong parameters - you must send an object containing a property named "_contract".

Hi,

As Martin mentioned, the service is expecting a parameter.

This is an example how to send a contract with three properties (_worker, _dayDateFrom, _dayDateTo)

var contract = new { _worker = empId, _dayDateFrom = fromDate, _dayDateTo = toDate }; string json = JsonConvert.SerializeObject(contract); Byte[] byteArray = Encoding.UTF8.GetBytes(json); request.Headers[OAuthHelper.OAuthHeader] = OAuthHelper.GetAuthenticationHeader(true); request.Method = "POST"; request.ContentLength = byteArray.Length; request.ContentType = "application/json"; using (var stream = request.GetRequestStream()) { stream.Write(byteArray, 0, byteArray.Length); }

Regards,

M

Thanks for all your responses. You were all correct, what threw me was the object to be sent must contain the parameter in the service.

If the service is

public PLMPricePriceList findEx(PLMFindPriceListContract _contract)

I would of expected like c# REST service to be able to

var contract = new PLMFindPriceListContract() { _worker = empId, _dayDateFrom = fromDate, _dayDateTo = toDate }; string json = JsonConvert.SerializeObject(contract);

However because the service requires a parameter of name "_contract" I had to wrap the PLMFindPriceListContract in another object like below

var contract = new PLMFindPriceListContractWrapper() { _contract = new PLMFindPriceListContract() { _worker = empId, _dayDateFrom = fromDate, _dayDateTo = toDate }}; string json = JsonConvert.SerializeObject(contract);

Many thanks for the comments
