Consuming web services

Microsoft Dynamics NAV provides an easy interface to create web services, which allow us to expose the NAV data with business logic and proper authentication. Now, let's see how to use these web services.

How to do it...

1. Let's get started by creating a new codeunit from Object Designer.

2. Add the function name as GetCustomer.

3. The function should take the following parameter:

   Name	DataType	Length
   CustNo	Code	20

4. Add the following local variable to the function:

   Name	DataType	Subtype
   Customer	Record	Customer

5. The function should return a text variable of length 50.

6. Add the following code to the function:

   IF Customer.GET(CustNo) THEN
     EXIT(Customer.Name)
   ELSE
     EXIT('Not Found!');

7. Save and close the codeunit.

8. Search for the Web Services page in RoleTailored client.

9. In the Web Services page, choose New.

10. Create a new web service with our codeunit ID, and in the service name, enter ConsumeWS.

11. Finally, mark the checkbox in the Published column.

12. Create a new Console Application...
