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)
    }
  )
)
