# Using Anypoint Code Builder to Configure A2A Connector 1.0

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Cloud IDE (Beta) is scheduled for retirement on August 31, 2026. August 30, 2026 is the last day you
can access Cloud IDE (Beta). Download your projects to work from Desktop IDE. Learn more in
[Migrate a Project from Cloud IDE to Desktop IDE](https://docs.mulesoft.com/anypoint-code-builder/int-import-mule-project#migrate-cloud-to-desktop).

To use Anypoint Code Builder to configure a connector or module, create a basic integration project
in Anypoint Code Builder, add connectors and other components to your Mule application to process
your business logic, and configure the attributes.

## Before You Begin

Before creating an integration project, you must:

- [Set up and access the Anypoint Code Builder web or desktop IDE](https://docs.mulesoft.com/anypoint-code-builder/start-acb)

- Have credentials to access the connector’s API

- Ensure that the Visual Studio Code Extension Pack for Java is installed.

To use this connector, you must be familiar with:

- The connector’s API

- Anypoint Connectors

- Mule runtime engine (Mule)

## Create a New Integration Project

To create a new integration project:

1.  In the activity bar of the IDE, click the
    ![Anypoint Code Builder icon](/mulesoft/current/en-us/connectors/_images/acb-icon-ms-logo.png) (**Anypoint Code
    Builder**) icon.

2.  From **Quick Actions**, click **Develop an Integration**:

    ![Develop an Integration link highlighted in the Getting started section](/mulesoft/current/en-us/anypoint-code-builder/_images/develop-integration-option-mat.png)

3.  Complete the following in the **Develop an Integration** form:

    <table><colgroup><col> <col></colgroup><thead><tr><th>Attribute</th><th>Value</th></tr></thead><tbody><tr><td><div><div><p><strong>Project Name</strong></p></div></div></td><td><div><div><p>Unique name for your project.</p></div><div><p>This name is used as the title and name of the integration project file. For example, if the project name is "Salesforce Integration," the project file name is <code>salesforce-integration</code>.</p></div></div></td></tr><tr><td><div><div><p><strong>Project Location</strong></p></div></div></td><td><div><div><p>Your home directory or another directory you create. Click <strong>Browse</strong> to select a different directory for the integration project.</p></div><div><p>Don’t create the project within another project directory.</p></div><div><p>See <a href="https://docs.mulesoft.com/anypoint-code-builder/start-add-folders">Adding Folders to Your Home Directory</a>.</p></div></div></td></tr></tbody></table>

4.  Select the type of project to create by selecting either the **Empty Project** or **Template or
    Example** card.

5.  Select the **Mule runtime** and **Java Version** for your app.

6.  Click **Create Project**.

## Add the Connector to Your Integration Project

Anypoint Connectors provide operations for retrieving, modifying, and sending data to and from
systems.

In addition to the
[built-in connectors](https://docs.mulesoft.com/anypoint-code-builder/acb-reference#builtin-connectors) that Anypoint
Code Builder provides, you can download many other connectors from Anypoint Exchange.

To import a connector from Exchange and add it to your configuration:

1.  In the Explorer view, open the configuration XML file for your project, such as
    `my-project-name.xml`.

2.  Click the
    ![Show Mule graphical mode icon](/mulesoft/current/en-us/anypoint-code-builder/_images/icon-tree-view.png) (**Show
    Mule graphical mode**) icon in the activity bar to open the canvas UI if it doesn’t open
    automatically.

3.  Add the connector the same way you added other components from the canvas UI:

    1.  In the canvas UI, click the
        ![Add component icon](/mulesoft/current/en-us/anypoint-code-builder/_images/icon-plus.png) (**Add component**)
        icon.

    2.  In the **Add Component** panel, click **Connectors**.

    3.  Click the connector name and then click the operation to add, such as **Publish**:

        ![Add Publish operation from Anypoint MQ Connector](/mulesoft/current/en-us/anypoint-code-builder/_images/int-add-connector-operation.png)

        If the connector is not available locally, click the
        ![Search in Exchange icon](/mulesoft/current/en-us/anypoint-code-builder/_images/icon-search-exchange.png)
        (**Search in Exchange**) toggle:

        ![Search in Exchange toggle](/mulesoft/current/en-us/anypoint-code-builder/_images/int-connector-search-exchange.png)

        <table><tbody><tr><td><i data-value="1"></i><b>1</b></td><td>Search locally</td></tr><tr><td><i data-value="2"></i><b>2</b></td><td>Search in Exchange</td></tr></tbody></table>

    4.  Select the connector to add to your project.

    5.  Select the operation from the **Add Component** panel.

Adding a connector to an integration project does not make that connector available to other
projects in your Anypoint Code Builder workspace.

## Configure the Source For the Flow

A source (trigger) starts the flow when specified conditions are met. You can configure these
sources for A2A Connector:

- **A2A Server - Task Listener**

  Listens for and receives incoming A2A protocol-compliant requests from other AI agents, enabling
  the Mule-based agent to act as an A2A server and respond to tasks.

- **A2A Server - On Task Stream Listener**

  Server-side listener for streaming task requests. Activates when clients send streaming requests
  to trigger server-side flows and enable real-time SSE event delivery. Use this source in
  conjunction with **A2A Server - Task Listener**.

- **A2A Server - On Push Notification Set Listener**

  Validates the push notification configuration before routing the request to the **A2A Server -
  Task Listener** source.

For example, to configure an **A2A Server - Task Listener** source, follow these steps:

1.  Click the **Task Listener** component on the canvas.

2.  (Optional) Click the edit icon to change the name of the **Task Listener** component.

3.  In the **General** tab, configure the connection for the A2A Server. See
    [A2A Server Configuration](https://docs.mulesoft.com/a2a-connector/1.0/a2a-connector-reference#Server).

4.  Select the **Advanced** tab to configure these attributes:

    <table><colgroup><col> <col> <col></colgroup><thead><tr><th>Attribute</th><th>Description</th><th>Required</th></tr></thead><tbody><tr><td><p>Primary node only</p></td><td><p>Select this option to execute the <strong>Task Listener</strong> source on the primary node only when running in a cluster.</p></td><td><p>No</p></td></tr><tr><td><p>Redelivery policy</p></td><td><p>Configures the redelivery policy for executing requests that generate errors. You can add a redelivery policy to any source in a flow.</p></td><td><p>No</p></td></tr><tr><td><p>Reconnection strategy</p></td><td><p>Retry strategy in case of connectivity errors. When an operation in a Mule application fails to connect to an external server, the default behavior is for the operation to fail immediately and return a connectivity error. You can modify the default behavior by configuring the reconnection strategy for the operation.</p></td><td><p>No</p></td></tr><tr><td><p>Response</p></td><td><p>The response payload to return. Defaults to <code>#[payload]</code>.</p></td><td><p>No</p></td></tr><tr><td><p>Response Headers</p></td><td><p>HTTP response headers to include with the response.</p></td><td><p>No</p></td></tr></tbody></table>

## Add Components to Your Project

Add components to your integration project to build a flow:

1.  In the **Explorer** view, open the XML file for your project, such as `my-project-name.xml`.

2.  Select **Build a Flow** from the start card to create an empty flow:

    ![Anypoint Code Builder canvas with starting cards with the options to start from scratch, build a flow, or build a subflow](/mulesoft/current/en-us/connectors/_images/acb-build-flow.png)

3.  Change the name of the flow:

    1.  Click **Flow**.

    2.  Click the edit icon.

        ![Arrow pointing to the flow name edit pencil icon](/mulesoft/current/en-us/connectors/_images/acb-change-flow-name.png)

    3.  Enter the flow name, and click the checkmark.

    4.  In the canvas UI, click the
        ![Add component icon](/mulesoft/current/en-us/anypoint-code-builder/_images/icon-plus.png) (**Add component**)
        icon.

    5.  In the **Add Component** panel, search for and select your component from the results. The
        following example shows the **Listener** component from the **HTTP** search results:

        ![Listener component highlighted in the Add Component section](/mulesoft/current/en-us/anypoint-code-builder/_images/main-tutorial-add-first-listener.png)

        The configuration XML file now includes the XML for the HTTP Listener into the `<flow/>`
        element, for example:

        ```XML
        <flow name="getFlights" >
          <http:listener path="" config-ref="" doc:name="Listener" doc:id="ojzfry" />
        </flow>
        ```

## Configure the Component Attributes

After you add components to your integration project, configure the attributes in the component UI,
or configure the attributes directly in the XML code editor.

Connector XML tags start with a namespace followed by an operation, following the syntax
`namespace:operation`, such as `<db:select/>` for a **Select** operation in Anypoint Connector for
Database (Database Connector).

You can use autocomplete from an expression (**fx**) field for a component to select DataWeave
functions from the Core module and other values accepted in this field.

## Create a New Configuration XML File

Anypoint Code Builder creates the initial Mule configuration XML file in `src/main/mule` within the
Mule project. This file contains global configurations and flow structures.

You can create additional configuration files, for example, to store global configurations.

To create a new XML configuration file:

1.  In the Explorer view, right-click the **mule** folder (`src/main/mule`) and select **New File**.

    Alternatively, use the menu.

    Show me how

    Select the `mule` folder, and then:

    - In the desktop IDE, select **File** > **New Mule Configuration File**.

    - In the cloud IDE, click the ![](/mulesoft/current/en-us/anypoint-code-builder/_images/icon-menu.png) (menu)
      icon, and select **File** > **New File**.

2.  Enter a name for the new file with the `.xml` extension.

3.  In the Editor view for the new file, press Ctrl+Space to display available options.

4.  Select **Empty mule configuration**:

    ![New Mule configuration option in auto-correct](/mulesoft/current/en-us/anypoint-code-builder/_images/int-new-mule-config.png)

    This command adds the following code to the file:

    ```xml
    <?xml version="1.0" encoding="UTF-8"?>
    <mule xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
        xmlns:ee="http://www.mulesoft.org/schema/mule/ee/core"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsd
        http://www.mulesoft.org/schema/mule/ee/core http://www.mulesoft.org/schema/mule/ee/core/current/mule-ee.xsd">

    </mule>
    ```
