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.
