# provideNolPayLinkCardComponent

This method allows you get a new instance of `NolPayLinkCardComponent` that can be used to link new
nol Pay cards.

```swift SWIFT theme={"dark"}
  func provideNolPayLinkCardComponent() -> NolPayLinkCardComponent
```

## Returns

An instance of `NolPayLinkCardComponent`.

**NolPayLinkCardComponent**

**start**

Initialize the component by calling the start function. This method should be called only once.

**updateCollectedData(collectableData: NolPayLinkCollectableData)**

Update component with collected data by passing an enum representing collectable data for linking a nol Pay card. This method can be called at any point, even if you have only partially collected data.
To validate the partially collected data, you can refer to the [validationDelegate](https://primer.io/docs/sdk/ios/v2.x.x/primer-headless-checkout/nol-pay-manager/provideNolPayLinkCardComponent.md#param-validation-delegate)

 

**enum NolPayLinkCollectableData**

**phoneData**

Enum member representing nol Pay phone data collected during the linking
process.

**Properties**

**mobileNumber** `String`

The mobile number in
[E.164](https://www.twilio.com/docs/glossary/what-e164) format for which
linked cards are to be retrieved.

**otpData**

Enum member representing nol Pay OTP (One-Time Password) data collected
during the linking process.

**Properties**

**otpCode**

The OTP code required for card linking.

**submit**

Call `submit` function in order to process collected data and move component to next state.

> [!NOTE]
>
> For `LinkCardComponent` you must call this function as a first step, to start NFC scanning of the card.

**stepDelegate** `PrimerHeadlessSteppableDelegate`

`NolPayLinkDataStep` is a enum class holding different output data
for specific steps. Whenever [submit](https://primer.io/docs/sdk/ios/v2.x.x/primer-headless-checkout/nol-pay-manager/provideNolPayLinkCardComponent.md#param-submit) will trigger the next step in case
the call to the mentioned method was successful.

**enum NolPayLinkDataStep**

**collectTagData**

Enum member representing the step of collecting tag data for nol Pay card linking.
This is a default/first step for linking flow. To start the linking flow you will have to call `submit` function after you called `start` function.

**collectPhoneData**

Enum member representing the step of collecting phone data for nol Pay card linking.

**Properties**

**cardNumber**

The card number associated with the nol Pay card scanned in `collectTagData` step.

**collectOtpData**

Enum member representing the step of collecting OTP (One-Time Password) data for nol Pay card linking.

**Properties**

**phoneNumber**

Phone number used for sending of OTP SMS.

**cardLinked**

Enum member representing the step of successfully linking a nol Pay card

```swift SWIFT theme={"dark"}
  func didReceiveStep(step: PrimerHeadlessStep)
```

**validationDelegate** `PrimerHeadlessValidatableDelegate`

Validation delegate will be triggered every time collected data is updated.

```swift SWIFT theme={"dark"}
  func didUpdate(validationStatus: PrimerValidationStatus, for data: PrimerCollectableData?)
```

**PrimerValidationStatus** `Enum`

`PrimerValidationStatus` is an enum that represents the different validation statuses in the Primer SDK. It helps to communicate the state of validation for a particular process, providing clear categorization of validation states.

**enum PrimerValidationStatus**

**validating**

Enum case representing the ongoing validation state.
This indicates that the validation process is currently in progress.

**valid**

Enum case representing a successful validation state.
This indicates that the validation process has completed successfully and the data is valid.

**invalid**

Enum case representing an unsuccessful validation state due to validation errors.
This indicates that the validation process has completed but has found one or more errors in the data.

**Associated Value**

**errors** `[PrimerValidationError]`

An array of `PrimerValidationError` representing the specific validation errors found.

**error**

Enum case representing an error state due to an unexpected issue.
This indicates that an unexpected error has occurred during the validation process.

**Associated Value**

**error** `PrimerError`

A `PrimerError` representing the unexpected error that occurred.

**errorDelegate** `PrimerHeadlessErrorableDelegate`

Error delegate will be triggered every time an error is thrown in the process.

```swift SWIFT theme={"dark"}
  func didReceiveError(error: PrimerError)
```
