Changing `rawData` triggers this callback. Some time after this is called, `primerRawDataManager(_:didReceiveMetadata:forState:)` will be called with the relevant metadata for the state. Use this method to indicate to the user that metadata is being fetched; for example, by showing a loading spinner or other UI until the metadata has been returned. ```swift SWIFT theme={"dark"} func primerRawDataManager(_ rawDataManager: PrimerHeadlessUniversalCheckout.RawDataManager, willFetchMetadataForState state: PrimerValidationState) ``` #### Parameters **Parameters** **rawDataManager** `PrimerHeadlessUniversalCheckout.RawDataManager` The instance of the raw data manager calling this delegate method. **state** `PrimerValidationState` An object containing the state that triggered the metadata fetch. For example, for card number entry, this will be an instance of `PrimerCardNumberEntryState` **Implementations** **class PrimerCardNumberEntryState** Used when `rawData` is set to `PrimerCardData` **Properties** **cardNumber** `String` *required* The card number set on `rawData` that triggered the metadata fetch ### primerRawDataManager(\_:didReceiveMetadata:forState:) Called when new validation metadata relating to the current validation state is received. This will always be called some time after `primerRawDataManager(_:willFetchMetadataForState:)` is called. Use this method to query new validation metadata, add informational UI, or allow the user to add additional payment information required to make a payment. ```swift SWIFT theme={"dark"} func primerRawDataManager(_ rawDataManager: PrimerHeadlessUniversalCheckout.RawDataManager, didReceiveMetadata metadata: PrimerPaymentMethodMetadata, forState state: PrimerValidationState) ``` #### Parameters **Parameters** **rawDataManager** `PrimerHeadlessUniversalCheckout.RawDataManager` The instance of the raw data manager calling this delegate method. **metadata** `PrimerPaymentMethodMetadata` An object containing metadata for the relevant `state` also returned with this method. **Implementations** **class PrimerCardNumberEntryState** Used when `rawData` is set to `PrimerCardData` **Properties** **cardNumber** `String` *required* The card number set on `rawData` that triggered the metadata fetch **state** `PrimerValidationState` An object containing the state that triggered the metadata fetch. For example, for card number entry, this will be an instance of `PrimerCardNumberEntryState` **Implementations** **class PrimerCardNumberEntryMetadata** Card network metadata including selectable card networks and detected card networks. **Properties** **source** `PrimerCardValidationSource` *required* Enum value indicating the source of the validation. **cases** **.remote** Indicates that remote validation occurred using Primer APIs. **.localFallback** Indicates that remote validation was attempted but could not be completed, causing a fallback to local validation. **.local** Indicates that the validation occurred locally, usually leveraging the first few digits of the card number. **selectableCardNetworks** `PrimerCardNetworksMetadata?` Card networks for the given card number that can be selected by the user prior to payment. This will be null in the case that a network is co-badged, or we are unable to remotely validate the given card number. **Properties** **items** `[PrimerCardNetwork]` *required* **Element** **cardNetwork** `PrimerCardNetwork` Represents a card network and includes metadata about that network relative to a specific card BIN. **network** `CardNetwork` *required* An enum value for the card network (e.g. `.visa`, `.mastercard`) **displayName** `String` *required* The human-readable name of the card network (e.g., Visa, Mastercard). **allowed** `Bool` *required* A boolean indicating whether this card network is allowed. **preferred** `PrimerCardNetwork?` The preferred card network. Use this to pre-select a network if there are multiple. **network** `CardNetwork` *required* An enum value for the card network (e.g. `.visa`, `.mastercard`) **displayName** `String` *required* The human-readable name of the card network (e.g., Visa, Mastercard). **allowed** `Bool` *required* A boolean indicating whether this card network is allowed. **detectedCardNetworks** `PrimerCardNetworksMetadata` All detected card networks for the given card number. This will include networks even if they are not merchant-supported. **Properties** **items** `[PrimerCardNetwork]` *required* **Element** **cardNetwork** `PrimerCardNetwork` Represents a card network and includes metadata about that network relative to a specific card BIN. **network** `CardNetwork` *required* An enum value for the card network (e.g. `.visa`, `.mastercard`) **displayName** `String` *required* The human-readable name of the card network (e.g., Visa, Mastercard). **allowed** `Bool` *required* A boolean indicating whether this card network is allowed. **preferred** `PrimerCardNetwork?` The preferred card network. Use this to pre-select a network if there are multiple. **network** `CardNetwork` *required* An enum value for the card network (e.g. `.visa`, `.mastercard`) **displayName** `String` *required* The human-readable name of the card network (e.g., Visa, Mastercard). **allowed** `Bool` *required* A boolean indicating whether this card network is allowed. ### primerRawDataManager(\_:didReceiveBinData:) Called when the SDK detects BIN data from the card number entered by the user. This callback provides detailed information about the card including issuer details and card attributes. It delivers BIN data independently from the metadata state callbacks and has a default no-op implementation, so overriding it is optional. ```swift SWIFT theme={"dark"} func primerRawDataManager(_ rawDataManager: PrimerHeadlessUniversalCheckout.RawDataManager, didReceiveBinData binData: PrimerBinData) ``` #### Parameters **Parameters** **rawDataManager** `PrimerHeadlessUniversalCheckout.RawDataManager` The instance of the raw data manager calling this delegate method. **binData** `PrimerBinData` **Properties** **preferred** `PrimerCardNetwork?` The recommended card network to use, based on the order specified in `orderedAllowedCardNetworks` in the Client Session. `nil` if no network is allowed or data is not yet resolved. **PrimerCardNetwork Properties** **network** `CardNetwork` *required* An enum value for the card network (e.g. `.visa`, `.mastercard`). **displayName** `String` *required* A human-readable name for the card network (e.g., "Visa", "Mastercard"). **issuerCountryCode** `String?` The ISO 3166-1 alpha-2 country code of the card issuer. **issuerName** `String?` The name of the card issuer (e.g., bank name). **accountFundingType** `String?` The type of account funding (e.g., "CREDIT", "DEBIT", "PREPAID"). **prepaidReloadableIndicator** `String?` Indicates whether a prepaid card is reloadable. **productUsageType** `String?` The usage type of the card product (e.g., "CONSUMER", "BUSINESS", "GOVERNMENT"). **productCode** `String?` The product code assigned by the card network. **productName** `String?` The product name assigned by the card network (e.g., "Visa Signature"). **issuerCurrencyCode** `String?` The ISO 4217 currency code associated with the card issuer. **regionalRestriction** `String?` Regional restrictions that apply to the card. **accountNumberType** `String?` The type of account number (e.g., "PAN", "TOKEN"). **alternatives** `[PrimerCardNetwork]` *required* All detected card networks, including ones that are not allowed. For co-badged cards, this list contains multiple networks. Each element has the same properties as `preferred` above. **status** `PrimerBinDataStatus` *required* The status of the BIN data retrieval. **Cases** **.complete** This happens when 8 digits or more are entered in the card number field. The SDK retrieved the BIN data using Primer's BIN data service, providing the most accurate information including issuer details. **.partial** This happens when fewer than 8 digits are entered in the card number field, or when the SDK fails to contact Primer's BIN data service. The SDK retrieved the card networks using static information bundled with the SDK. This can only identify international card networks and does not include issuer details. **firstDigits** `String?` The first digits (BIN prefix) of the card number, when available. ### primerRawDataManager(\_:metadataDidChange:) > [!WARNING] > > This method is deprecated. Please use `primerRawDataManager(_:willFetchMetadataForState:)` and > `primerRawDataManager(_:didReceiveMetadata:forState:)`. Returns validation metadata for the current validation state, triggered by using `rawData`. Check the section below for the metadata types that can be returned. ```swift SWIFT theme={"dark"} func primerRawDataManager(_ rawDataManager: PrimerHeadlessUniversalCheckout.RawDataManager, metadataDidChange metadata: [String: Any]?) ``` #### Parameters **Parameters** **rawDataManager** `PrimerHeadlessUniversalCheckout.RawDataManager` The instance of the raw data manager calling this delegate method. **metadata** `Dictionary\` The metadata associated with the validation state.
