Hello 
 
 Integrations can be called like any other expression rules on interfaces, if it is a GET method integration you can call it in local variables or anywhere else on the interface. 
 Example 
 a!localVariables(
 /* Call the integration to query the external system */
 local!externalQuery: rule!GetUnsettledTransactionList(),
 
 /* Handle the response depending on the outcome */
 local!value: if(local!externalQuery.success,
 local!externalQuery.result,
 local!externalQuery.error
 )
) 
 
 If it is a POST method integration, it can be called only in the saveinto parameter on the interface. 
 
 Example 
 a!buttonWidget(
 label: "Place Your Order",

 /* Call the integration to update the external system when the button is pressed */
 saveInto: rule!AuthorizeCreditCardPayment(
 cardNumber: local!cardNumber,
 expirationDate: local!expirationDate,
 ccv: local!ccv,
 amount: local!amount,
 onSuccess: {
 /* Handle the successful response */ 
 a!save(local!result, fv!result)
 },
 onError: {
 /* Handle the error response */ 
 a!save(local!paymentErrorMessage, fv!error.message)
 }
 )
) 
 
 For detailed explanation please refer to the following documentation link
