IMessaging.Send()

Description:

The Send method sends an SMS or MMS message.

This method can be called both synchronously and asynchronously.

Syntax:

For synchronous calls:

result = so.IMessaging.Send(criteria);

+ +

For asynchronous calls:

result = so.IMessaging.Send(criteria, callback);

+ +

Arguments:

criteria:
+ +
This is an object that specifies the type and details of the message +to send. For more information about the object properties and how to define +them, see section Criteria for sending a message.
+ +
callback:
+ +
The callback argument is the name of the method +that is executed when an asynchronous Send call has status +information to return. You must define this method separately. Follow the +instructions in section Defining the callback handler for an asynchronous method to +define the callback method.
+
This argument is used only with an asynchronous Send call.
+ +

Return value:

If synchronous, the Send method returns an object +that contains an error code and an error message.

If asynchronous, the method returns an object that contains a transaction +ID for the callback instance, +an error code, and an error message (see the following table). When the asynchronous +call has completed, callback returns an object that contains +an error code and an error message (see Table: +Callback return value).

+ + + + + + + + + + + + + + + + + + + + + +

**Table:** Return value +properties for Send
+ Property +	+ Description +	+ Value +
+ `result.ReturnValue` +	+ This is a number used as an identification to match transactions started +with an asynchronous `Send` call to one or more calls it +generates to `callback`. + This property is only valid for asynchronous calls. +
+ `result.ErrorCode` +	+ This is a number that specifies a predefined error code. +	+ See Service API error codes. +
+ `result.ErrorMessage` +	+ This is a text string that describes the error. +	+ See Messaging Service API error messages. +

Remarks:

Apart from status information and transaction IDs for asynchronous calls, +the Send method does not return any result information.
