Using Anypoint Studio to Configure Twilio Connector 4.2 - Mule 4

Anypoint Studio (Studio) editors help you design and update your Mule applications, properties, and configuration files.

To add and configure a connector in Studio:

Create a Mule project.
Add the connector to your Mule project.
Configure a source for the connector’s flow.
Add a connector operation to the flow.
Configure a global element for the connector.
Configure the Other Connector Fields.

When you run the connector, you can view the app log to check for problems in real time, as described in View the App Log.

Create a Mule Project

In Studio, create a new Mule project in which to add and configure the connector:

In Studio, select File > New > Mule Project.
Enter a name for your Mule project and click Finish.

Add the Connector to Your Mule Project

Add Twilio Connector to your Mule project to automatically populate the XML code with the connector’s namespace and schema location and to add the required dependencies to the project’s pom.xml file:

In the Mule Palette view, click (X) Search in Exchange.
In the Add Dependencies to Project window, type twilio in the search field.
Click Twilio Connector in Available modules.
Click Add.
Click Finish.

Adding a connector to a Mule project in Studio does not make that connector available to other projects in your Studio workspace.

Configure a Source

A source initiates a flow when a specified condition is met. You can configure one of these sources to use with Twilio Connector:

HTTP Listener
Initiates a flow each time it receives a request on the configured host and port
Scheduler
Initiates a flow when a time-based condition is met

For example, to configure an HTTP Listener source, follow these steps:

In the Mule Palette view, select HTTP > Listener.
Drag Listener to the Studio canvas.
On the Listener configuration screen, optionally change the value of the Display Name field.
Specify a value for the Path field.
Click the plus sign (+) next to the Connector configuration field to configure a global element that can be used by all instances of the HTTP Listener source in the app.
On the General tab, specify the connection information for the connector.
On the TLS tab, optionally specify the TLS information for the connector.
On the Advanced tab, optionally specify reconnection information, including a reconnection strategy.
Click Test Connection to confirm that Mule can connect with the specified server.
Click OK.

Add a Connector Operation to the Flow

When you add a connector operation to your flow, you are specifying an action for that connector to perform.

To add an operation for Twilio Connector, follow these steps:

In the Mule Palette view, select Twilio Connector and then select the desired operation.
Drag the operation onto the Studio canvas and to the right of the source.

Configure a Global Element for the Connector

When you configure a connector, it’s best to configure a global element that all instances of that connector in the app can use. Configuring a global element requires you to provide the authentication credentials that the connector requires to access the target Twilio API. Twilio Connector supports Basic authentication, which uses the Twilio Account SID as the username and Auth Token as the password.

To configure the global element for Twilio Connector, follow these steps:

Select the name of the connector in the Studio canvas.
Select the operation in the Studio canvas.
In the configuration screen for the operation, click the plus sign (+) next to the Connector configuration field to access the global element configuration fields.

You can reference a configuration file that contains ANT-style property placeholders (recommended), or you can enter your authorization credentials in the global configuration properties. For information about the benefits of using property placeholders and how to configure them, see Anypoint Connector Configuration.
On the Advanced tab, optionally specify an expiration policy.
Click Test Connection to confirm that Mule can connect with the specified server.
Click OK.

Configure Additional Connector Fields

Depending on the operation, configure the following fields on the operation’s properties window:

Field Description

Field	Description
Account sid	Unique ID of the account that sent this message
Message sid	Unique ID for the message
Media sid	Unique ID for the media
Date Created	Date on which the target media was created on Twilio, formatted as `YYYY-MM-DD`
Date Sent	Date on which the target message was sent from Twilio, in RFC 2822 format
From	Phone number or sender ID that initiated the message, in E.164 format
To	Phone number that received a message, in E.164 format

Account sid

Unique ID of the account that sent this message

Message sid

Unique ID for the message

Media sid

Unique ID for the media

Date Created

Date on which the target media was created on Twilio, formatted as YYYY-MM-DD

Date Sent

Date on which the target message was sent from Twilio, in RFC 2822 format

From

Phone number or sender ID that initiated the message, in E.164 format

Phone number that received a message, in E.164 format

For more information about each format, see the See Also section at the end of this document.

View the App Log

To check for problems, you can view the app log as follows:

If you’re running the app from Anypoint Platform, the output is visible in the Anypoint Studio console window.
If you’re running the app using Mule from the command line, the app log is visible in your OS console.

Unless the log file path is customized in the app’s log file (log4j2.xml), you can also view the app log in the default location MULE_HOME/logs/<app-name>.log.
