# Create a Configuration File for Slack and Salesforce
Cloud IDE 
Desktop IDE 
**Open Beta Release** : The **cloud IDE is in open beta**. Any use of Anypoint Code Builder in its beta state is subject to the applicable beta services terms and conditions, available from the IDE.
A configuration file is a YAML file that can reference different configurations and specify different values for your connector properties. Configuration files enable you to define specific properties depending on the environment to which you are deploying your application.
To start configuring your Slack and Salesforce connectors in your escalation API, create a configuration file.
## Before You Begin
Complete Integrate Salesforce Data into Slack and Email Notifications.
## Create a Configuration File
  1. In your Explorer view, right-click the **resources** folder (`src/main/resources`) and select **New File** :
  2. Name the file `config.yaml`.
  3. Populate your file with your Salesforce, Gmail, and Slack configurations:
```
salesforce:
 username: "yourUserName"
 password: "yourPassword"
 token: "yourToken"
email:
 host: "smtp.gmail.com"
 username: "yourGmailEmail"
 password: "yourEmailAppPassword"
slack:
 token: "yourSlackToken"
```

  4. Navigate to your `new-case-salesforce.xml` file, add a new line before the `</mule>` tag, type `configuration` and select **mule:configurationProperties** :
  5. Scroll through the attributes and set the value of `file` to `config.yaml`:
```
<configuration-properties file="config.yaml" doc:name="Configuration properties" />
```



## Configure Your Salesforce Connector
Use the values in your `config.yaml` file to connect the Salesforce Connector to your Salesforce environment:
  1. In your `new-case-salesforce.xml` file, create a new line after the `<configuration-properties/>` element, type `salesforce`, and select **salesforce:sfdc-config** :
  2. Set the **name** field to `Salesforce-Config`.
  3. Create a new line, type `basic` and select **Salesforce:Basic** :
  4. Configure the `username` and `password` properties to use your configuration file values:
```
<salesforce:basic-connection username="${salesforce.username}" password="${salesforce.password}" securityToken="${salesforce.token}" />
```

When you move your cursor over the `${salesforce.username}` and `${salesforce.password}` elements, Anypoint Code Builder shows the values from the configuration file.  
---  
  5. Verify your connection to Salesforce by clicking **Test Connection** for the `<salesforce:sfdc-config/>` element:
Anypoint Code Builder returns a **Connection is valid** message.
If you get an error, verify the error message to troubleshoot further.


## Add a Salesforce Trigger
  1. Add a new flow on your canvas.
  2. In the code editor, name the flow `​NewSalesforceCaseFlow`:
```
<flow name="​NewSalesforceCaseFlow">
</flow>
```

  3. On your canvas, click the (**Add component**) icon after **Flow** , type `new object`, and select **On new object** after **Salesforce**.
  4. In the code editor, set the following values of the `<salesforce:new-object-listener/>` element:
     * `objectType`: **Case**
     * `config-ref`: **Salesforce-Config**
     * `name`: **On New Case**
  5. In the `<salesforce:new-object-listener/>` element, replace `<scheduling-strategy/>` with the following snippet:
```
<scheduling-strategy >
 <fixed-frequency frequency="1000"/>
</scheduling-strategy>
```



## Test Your Salesforce Integration
  1. Add a logger at the end of your flow:
A `logger` component is added to the `flow` snippet in the code editor.
  2. Replace the `logger` component in the code editor with the following:
```
<logger level="INFO" doc:name="Log Case Object" message="{#payload}" />
```

  3. Add a breakpoint to this line by clicking the red dot at the line number:
Alternatively, add a breakpoint to the `logger` component by right-clicking on the component in the canvas UI and selecting **Add Breakpoint**.
  4. Select **Run** > **Start Debugging (F5)**.
  5. After your application deploys successfully, log in to your Salesforce account.
  6. From **App Launcher** , select **Service** :
  7. Select **Cases** > **New Case** :
  8. Ensure that the **Status** of the new case is **New**.
  9. Create a new case and save it.
  10. In Anypoint Code Builder, your application stops at the logger. Inspect the payload in **Variables** :
The payload contains information about your newly created case.
  11. Step over your Logger component.
  12. Proceed to Extract Payload Information to Variables to learn how to extract your case information to a variable to use it later in the flow.
