    hi Anurag,

    An Apex callout enables you to tightly integrate your Apex code with an external service. The callout makes a call to an external web service or sends an HTTP request from Apex code, and then receives the response.
    Apex callouts come in two flavors.

    • Web service callouts to SOAP web services use XML, and typically require a WSDL document for code generation.
    • HTTP callouts to services typically use REST with JSON.
