API Reference
Complete API reference for the Bolt iOS SDK — delegates, result types, callbacks, and data models.

This page provides the complete reference for all delegate protocols, result types, and data models in the Bolt iOS SDK (BoltInternal).

BoltSimpleCheckoutDelegate

Implement this delegate when using startCheckout(config:delegate:) or BoltCheckoutViewController(config:delegate:).

Callback Parameters Description
onCheckoutSuccess(result:) result: BoltCheckoutResult Called when the user completes checkout and payment is authorized. Use result.cart?.orderReference, result.reference, and result.merchantOrderNumber to reconcile with your backend.
onCheckoutError(errorReason:) errorReason: String Called when checkout fails due to a network error, payment decline, validation failure, or other unexpected issue.
onCheckoutCancel() (none) Called when the user dismisses the checkout UI. The order token remains valid for a subsequent attempt.

BoltCheckoutResult

onCheckoutSuccess receives a BoltCheckoutResult that mirrors Bolt’s ClientTransactionView. All fields are optional where the type allows nil.
