(0) ShareShare

Posted on by junior AX 1,552

I created a new custom service and a service group (auto deploy : yes). I also created a class with a method that retrieves the customer ids. and i added this method in the service.

i made a job to make sure that my method return customer ids and it did return successfully.

Now i put the following URL:  https://YouInstanceUrl/api/services/ServiceGroupTest/TestService/getCustomerId

when i open the file i don't get any customer ids why is that?

I have the same question (0)

    Yes but how? Do you call it from some application? Or do you open this URL via a browser?

    It's not supposed to be used via a browser.

    Services are something that you use for integrations between systems. They should be used from code, not from browser.

    You can find links to code examples in the end of this article: docs.microsoft.com/.../custom-services

    Check Program.cs, that's where the call to the service is. Before that, your code needs to authenticate with AAD.

    It would help if you shared with us what business requirement you are trying to solve. Now you asked about calling a custom service but it seems you might have not known what custom services are. Anyway, you use custom services to expose x++ business logic to external applications. So, external application can call the service and trigger something in D365. Or get some information from D365. Or both.

    this is my scenario, an external system should send me parameters of the customer account they want to retrieve information about and i'll get this information from D365FO.

    Here is my class: 

    class CustomerCustomService
{
    [SysEntryPointAttribute(true),

        AifCollectionTypeAttribute('return', Types::Class, classStr(CustomerCustomService)),

        AifCollectionTypeAttribute('_custList', Types::String)]

        public List retrieveCustomerInfo(List _custList)

    {

        CustomerCustomServiceContract    dataContract;

        ListEnumerator  listEnum = _custList.getEnumerator();

        List            resultSet = new List(Types::Class);

        CustTable       custTable;

 

        while (listEnum.moveNext())

        {

            select firstOnly custTable

            where custTable.AccountNum == listEnum.current();

 

            dataContract = new CustomerCustomServiceContract();

 

            if (custTable)

            {

                dataContract.parmCustGroupId(custTable.CustGroup);

                dataContract.parmCustName(custTable.name());

                dataContract.parmDefaultLanguage(custTable.languageId());

            }

 

            resultSet.addEnd(dataContract);

        }

 

        return resultSet;

    }

}

    1)  do i need to use sysEntryPointAttribute(true) and what does it mean? and does my class need to extend anything?

    2) is there a way to call the service using c# code without AAD? if not what i need to do exactly?

    1) SysEntryPointAttribute is not needed in d365, you will actually get a best practice warning about it when you compile your code

    2) You must always authenticate with AAD in order to communicate with D365FO. You can find a example here: github.com/.../AuthenticationUtility

    1) what does it mean, i read that it checks authorization but i didn't get it? and does my class need to to extend SysOperationServiceBase?

    2) so for testing purposes i can't create a c# project to call it and do what they used to do in AX 2012? I'll take a look at the link now.
