What Is Callout In Salesforce
A callout in Salesforce refers to the process of making an HTTP request to an external service from Apex code. Callouts are essential for integrating Salesforce with external systems, allowing you to fetch or send data between the platforms. This capability is particularly useful for automating business processes, updating records in real-time, or fetching information from third-party applications. Salesforce provides various options for making callouts, such as RESTful services, SOAP web services, and external systems connected through Salesforce Connect. By leveraging callouts, organizations can enhance the functionality and connectivity of their Salesforce instance, streamlining operations and improving overall efficiency.
