The Salesforce connector establishes a connection to the Salesforce system using a SOAP web service (provided by Salesforce). Almost every operation that can be done via the Salesforce API can be done through this connector. This connector will also work if your Salesforce objects are customized with additional fields, or even if you are working with custom objects. The connector supports the option to configure Salesforce connection details, connection pooling, and max limit of active connections.

• Configuration: This element must be placed outside of your flows and at the root of your Mule application. You can create as many configurations as you deem necessary as long as each carries its own name.

• Connection Pool: The Salesforce connector offers automatic connection management via the use of a connection pool. The pool will act as a storage mechanism for all the connections that are in use by the user of this connector.

• Reconnection Strategies: Reconnection strategies specify how a connector behaves when its connection fails. You can control how Mule attempts to reconnect by specifying a number of criteria.

Prerequisites

1. Create a Salesforce account if you don't have one.

2. Reset the Security Token. Go to My Settings > personal > reset my security token. Click "Reset Security Token" and it will send a security token to your registered email.

3. Create an Accounts View with Postal Code in Salesforce.

4. Create a new object as per the requirement, or use an existing one.

5. Create a Mule Flow to perform business logic and integration.
