# Identify Multiple Calls Using CreateOptions and ConversationID

A request can have an external unique identifier, typically the ConversationID. If you don't specify a ConversationID, include the RequestID. The API processes the calls in the order specified.

## C# Example

```csharp
CreateOptions co = new CreateOptions();
co.CallsInConversation = 3;
co.CallsInConversationSpecified = true;
co.ConversationID = "1234567";
co.SequenceCode = 1;
co.SequenceCodeSpecified = true;
co.RequestType = RequestType.Asynchronous;
co.RequestTypeSpecified = true;
CreateResult[] results = integrationFramework.Create(co, new APIObject[] { ts }, out requestID, out status);
```

## SOAP Envelope

```xml
<soap:Body>
    <CreateRequest xmlns="http://exacttarget.com/wsdl/partnerAPI">
        <Options>
            <RequestType>Asynchronous</RequestType>
            <ConversationID>1234567</ConversationID>
        </Options>
...
```
