In your integration, depending on the direction, you may want to read from one system and write to another. eg: Read a customer from GP, map it to CRM account fields and push it to CRM.
Here is a code sample from MSDN which retrieves a customer card from GP -
// Specify the Microsoft Dynamics GP server and database in
// the connection string
sConnectionString = @"data source=MySrvr;initial catalog=TWO;
integrated security=SSPI;persist security info=False;
packet size=4096";
// Specify the customer to retrieve
eConnectOut myRequest = new eConnectOut();
myRequest.DOCTYPE = "Customer";
myRequest.OUTPUTTYPE = 1;
myRequest.INDEX1FROM = "Customer001";
myRequest.INDEX1TO = "Customer001";
myRequest.FORLIST = 1;
// Create the eConnect requester XML document object
RQeConnectOutType[] eConnectOutType =
new RQeConnectOutType[1] { new RQeConnectOutType() };
eConnectOutType[0].eConnectOut = myRequest;
eConnectType eConnectDoc = new eConnectType();
eConnectDoc.RQeConnectOutType = eConnectOutType;
// Serialize the object to produce an XML document
MemoryStream memStream = new MemoryStream();
XmlSerializer serializer = new XmlSerializer(typeof(eConnectType));
serializer.Serialize(memStream, eConnectDoc);
memStream.Position = 0;
XmlDocument myDoc = new XmlDocument();
myDoc.Load(memStream);
// Retrieve the specified customer document
string myCustomer = e.GetEntity(sConnectionString, myDoc.OuterXml);
Here is a code sample taken directly off the CRM 4.0 SDK for Creating an account. There are a lot of other samples on retrieving/updating entities and much more -
// Set up the CRM Service.
CrmAuthenticationToken token = new CrmAuthenticationToken();
// You can use enums.cs from the SDK\Helpers folder to get the enumeration for Active Directory authentication.
token.AuthenticationType = 0;
token.OrganizationName = "AdventureWorksCycle";
CrmService service = new CrmService();
service.Url = "http://<servername>:<port>/mscrmservices/2007/crmservice.asmx";
service.CrmAuthenticationTokenValue = token;
service.Credentials = System.Net.CredentialCache.DefaultCredentials;
// Create the account object.
account account = new account();
// Set the properties of the account object.
account.name = "Fourth Coffee";
account.address1_line1 = "23 Market St.";
account.address1_city = "Sammamish";
account.address1_stateorprovince = "MT";
account.address1_postalcode = "99999";
account.donotbulkemail = new CrmBoolean();
account.donotbulkemail.Value = true;
// Create the target object for the request.
TargetCreateAccount target = new TargetCreateAccount();
// Set the properties of the target object.
target.Account = account;
// Create the request object.
CreateRequest create = new CreateRequest();
// Set the properties of the request object.
create.Target = target;
// Execute the request.
CreateResponse created = (CreateResponse)service.Execute(create);
Do you have eConnect and CRM installed locally? There are some samples that come with the eConnect install. Alternatively, you may install this - http://www.microsoft.com/download/en/details.aspx?id=8870
