# Handle referrals

[View source](/point-of-sale/classic-library-deprecation/classic-library-integrations/ios-integration/key-steps-ios/process-a-basic-transaction-ios/handle-referrals-ios.md)

## Delegate

The `transactionRequiresReferral` delegate is called when a transaction requires referral.

After this method has been called, transaction-processing will be paused until `submitReferralWithCode` is called on the given `referralRequest`.

This method must be implemented to ask for referral authorization code.
