    <version>x.x.x</version>
    <classifier>mule-plugin</classifier>
</dependency>

Navigate through the project’s structure and double-click src/main/app/smc-usecase-create-object.xml.
Search for the HTTP component in the Mule Palette view.
Drag the Listener operation onto the canvas.
Search for Transform Message and drag the component after the Listener.
Search for Salesforce Marketing Cloud and drag the Create entities operation after Transform Message.
Add a Transform Message component after Create.
Double-click on the Listener component.
Click next to the Connector configuration field.
Specify the Host as localhost and Port as 8081, then click OK.
Specify the Path as /create.
Double-click Create.

Specify the required fields with the credentials for your organization and click OK.
From the Object type drop-down select List.
Double-click Transform Message (to the left of Create in the flow) and configure as shown below:
Double-click Transform Message (to the right of Create in the flow) and configure as shown below:
Deploy the app.
Use a REST client to make a POST request to x-www-form-urlencoded to localhost:8081/create with the following parameter payload: listName=testlist.

For example, curl -d listName=MyName-Test localhost:8081/create.
Go to your instance and check that the list was created.

You can use a similar flow for other connector operations, such as Upload and Delete, but you must change the Object Type in the Salesforce Marketing Cloud to the name of the object that you are going to create, and remap fields on the Transform Message component as needed.

Known Issues and Limitations

Salesforce Marketing Cloud Connector has some limitations, including when:

Working with subclasses inside complex fields
Trying to retrieve fields from a hierarchy
Attempting to return an Automation object.

Working with Subclasses Inside Complex Fields

Some objects in Salesforce Marketing Cloud have complex fields, such as the Recurrence field, which belong to a base class. DataSense can only bring up fields specific to the base class.

To use additional fields that belong to a subclass of a base class, manually add the desired fields to the Transform Message component. For Salesforce Marketing Cloud to know that you want to work with a subclass and recognize the fields you added, you must also add a field called concreteClassType of type String whose value is the name of the subclass.

See Providing a Subclass as a Type to a Complex Field for an example detailing how to achieve this.

Retrieve Operation Limitations

The Retrieve operation enables you to retrieve records in a SQL query-like fashion. When you use the Retrieve operation, Salesforce Marketing Cloud prevents the retrieval of fields that are part of a hierarchy. For example, the Subscriber object has a complex structure:

The API only allows you to query fields on the first level, such as EmailAddress or SubscriberKey, but not fields such as Attributes.Name.

The Retrieve operation supports filters for querying the data. However the filters do not behave like an SQL filter condition. For example, a clause such as WHERE 1=1 works in SQL, but results in an error in Salesforce Marketing Cloud because the API doesn’t support it. In this example, the operand to the left of the equal sign must be a valid property of the Salesforce data extension (SFDE).

When executing the request with the WHERE 1=1 clause, the filter expects a property. It is transformed into the following request:

<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="SimpleFilterPart"> <Property>1</Property> <SimpleOperator>equals</SimpleOperator> <Value>1</Value> </Filter>.

The response is:

`<OverallStatus>Error: The Filter Property '1' is not a retrievable property.</OverallStatus>`.

When filtering the results of a query, only the following operators are supported in WHERE clauses:

Operator	Salesforce Marketing API equivalent
=	equals
<>	notEquals
>	greaterThan
>=	greaterThanOrEqual
<	lessThan
⇐	lessThanOrEqual
like	like

Operator

Salesforce Marketing API equivalent

equals

notEquals

greaterThan

greaterThanOrEqual

lessThan

⇐

lessThanOrEqual

This connector does not send the SQL query to the Salesforce server as is. Instead, the query is parsed and transformed into an XML object before it is sent. Because of this, any filters that are not included in the table above or any SQL syntax features, such as LIMIT, OFFSET, ALIAS, or JOINs, are unsupported. For more details, refer to the Salesforce API Guide.

Server Results Containing an Automation Object

Server results that contain an Automation object cause an exception to be thrown. When performing an operation, such as Create or Delete, on an Automation object, the returned result contains the structure of the Automation object you acted upon. The server also returns an additional field in the Automation object called isPlatformObject that is not recognized by the WSDL.

To bypass this issue, make all operations that directly use an Automation object asynchronous. If an operation is asynchronous, the immediate response of the operation is Operation Queued.

For more information, see Asynchronous Operations.

Common Use Cases

Use Salesforce Marketing Cloud Connector operations for the following common use cases:

Configure action operation - Calls the Configure method with Create, Delete, or Update as the value of the Action parameter when connected to the Marketing Cloud API SOAP web service.
Create entities operation - Creates new objects on the Marketing Cloud API web server.
Delete objects operation - Deletes existing objects on the Marketing Cloud API web server.
Perform operation - Calls the Perform method with the GetMaxCount, Start, or Stop as the value of the Action parameter when connected to the Marketing Cloud API SOAP web service.
Retrieve entities operation - Retrieves objects from the Marketing Cloud API web server in a SQL query-like fashion.
Schedule start operation - Calls the Schedule method with Start as the value of the Action parameter when connected to the Marketing Cloud API SOAP web service.
Update entities operation - Updates existing objects on the Marketing Cloud API web server.
Upsert entities operation - Creates objects on the Marketing Cloud API web server if the objects do not already exist, or updates existing objects on the server.

Add a Proxy

To use a proxy server, set the following configuration properties on the Advanced tab of your configuration:

Providing a Subclass as a Type to a Complex Field

Suppose you want to schedule an existing Automation that sends emails to a subscriber list once per minute. To do this, add a Schedule Reference to the connector through a flow variable:

Use the Recurrence field in ScheduleDefinition to provide information such as how much time to pass between sending emails. The Recurrence field is a complex field that has no structure.

To specify a MinutelyRecurrence instead of a Recurrence:

Manually add the fields belonging to the MinutelyRecurrence class.
Add an additional field called concreteClassType of type String whose value is the name of the subclass.

The mapping for the ScheduleDefinition looks like this in the example:

This map has a field called minuteInterval that belongs to a subclass of Recurrence called MinutelyRecurrence.

For the connector to use the MinutelyRecurrence object, you must also add the concreteClassType field with MinutelyRecurrence as the value.

Asynchronous Operations

Most operations are synchronous by default, meaning that the connector waits for the result of the operation. For more details regarding the operations of the Marketing Cloud API, access the Salesforce Marketing Cloud Methods documentation.

To specify that you want an operation to behave asynchronously, use the Options parameter for the operation.

The following example creates a list of Automation objects to provide in the payload. Because the result of any operation that works directly with Automation objects throws an exception caused by the presence of an unknown field, the example uses the CreateOptions parameter to make the call asynchronous. In this example, the CreateOptions value is provided in a variable called vars.

This mapping for CreateOptions in vars looks like this:

The requestType field determines the type of call (SYNCHRONOUS or ASYNCHRONOUS).
The conversationID field assigns a unique identifier to the asynchronous call.

You can group asynchronous calls together using the conversationID, callsInConversation, and sequenceCode fields. For example, suppose you want to make five asynchronous calls to the server, execute the calls together, and specify their execution order. To do this:

Assign the same conversationID to each call.
Set the callsInConversation field to 5.
Use the sequenceCode field to order the calls.

The following example has a single call, so it passes a value of 1 to callsInConversation and sequenceCode.

The Options parameter has more functionality than shown in this example. For more information, see the Salesforce Marketing Cloud Objects documentation.
