class Fidel

This class is designed as a facade, used to configure the card enrollment process, via many of its static properties, and start the card enrollment flow. It's also the class that provides callbacks that might be useful for your application.

Properties

Mandatory properties

These are properties that must be set correctly. In the case where one of these properties are not set or they are set incorrectly, the SDK will return an error in the onResult callback (of type: FidelErrorType.SdkConfigurationError).

sdkKey: String

This key is used to authenticate your Fidel API account. Get it from your Fidel API dashboard -> Account Settings -> SDK Keys section.

Important note: For security reasons, please DO NOT store the SDK Key in your codebase. Follow our SDK security guide for detailed recommendations.

Note: If you use a test SDK Key, your users can only enroll test card numbers.

programId: String

The program ID indicates the Fidel API program in which the cards will be enrolled. Get the program ID by navigating to the Fidel API dashboard -> Programs section -> Click on the ID of the program you want to use. Clicking on it will copy the ID in your pasteboard.

companyName: String

By setting this property we customize the consent text, that the cardholder needs to read and agree with, before enrolling a card.

The maximum number of characters allowed for this property is 60.

termsAndConditionsUrl: String

You need to set your terms and conditions URL if you would like to:

  1. support all the countries that Fidel API supports

  2. set a specific allowedCountries set of countries AND include US or Canada in it.

By setting this property we add a link to your Terms & Conditions in the consent text. The cardholder needs to read and agree with your terms, before enrolling a card.

Optional properties

supportedCardSchemes

Type: Set<CardScheme>

Default value: setOf(CardScheme.VISA, CardScheme.MASTERCARD, CardScheme.AMERICAN_EXPRESS)

Sets a list of supported card schemes. If a card scheme is supported, cardholders will be able to enroll their card. If a card scheme is not in the list, then the cardholders will see an error message while typing or pasting the unsupported card number.

If you set a null value, you will not be able to start the Fidel SDK enrollment flow. In this case, immediately after attempting to start the flow, you will receive an error in the onResult callback (of type: FidelErrorType.SdkConfigurationError).

enum class CardScheme

Cases:

  • VISA, MASTERCARD, AMERICAN_EXPRESS

allowedCountries

Type: Set<Country>

Default value: setOf(Country.CANADA, Country.IRELAND, Country.JAPAN, Country.NORWAY, Country.SWEDEN, Country.UNITED_ARAB_EMIRATES, Country.UNITED_KINGDOM, Country.UNITED_STATES)

Sets the list of countries that cardholders can pick to be the card issuing country. When two or more countries are set, cardholders will be able to select the card issuing country with our country selection UI.

If you set a value with only one country (size of this set == 1), the country selection UI will not be displayed in the card enrollment screen. The country that you set will be considered the card issuing country for all cards enrolled in your Fidel API program using the SDK.

If you set an empty value, you will not be able to start the enrollment flow. Instead you will receive an error in the onResult callback (FidelErrorType.SdkConfigurationError), immediately after the attempt to start.

enum class Country

Cases:

  • CANADA, IRELAND, JAPAN, NORWAY, SWEDEN, UNITED_ARAB_EMIRATES, UNITED_KINGDOM, UNITED_STATES

deleteInstructions: String

Default value: "going to your account settings"

This text informs the cardholder how to opt out of transaction monitoring in your program. It is appended at the end of the consent text. The maximum number of characters allowed for this property is 60.

defaultSelectedCountry: Country

Default value: UNITED_KINGDOM

Sets the Country that will be selected by default when the user opens the card enrollment screen. If the defaultSelectedCountry is not part of the allowedCountries list, then the first country in the allowedCountries list will be selected.

privacyPolicyUrl: String?

Default value: null.

If you provide a value for this parameter, the card enrollment consent text will include a phrase that will provide the user with more privacy related information at the URL that you provide.

When the value of this parameter remains null no such phrase will be displayed in the card enrolling consent text.

If you provide an invalid URL string, you will not be able to start the card enrollment flow. Instead you will receive an error in the onResult callback (FidelErrorType.SdkConfigurationError), immediately after attempting to start the card enrollment flow.

metaData: org.json.JSONObject?

This is a JSONObject that you can use to associate custom data with an enrolled card.

We advise setting an "id" key -> value pair in this JSONObject. Later, it might be useful for you to use our List Cards from Metadata ID API Endpoint to query for cards using this ID.

Example of meta data that you can set:

123456
val jsonMetaData = JSONObject()
jsonMetaData.put("id", "this-is-the-metadata-id")
jsonMetaData.put("myUserId", "123")
jsonMetaData.put("customKey", "customValue")
Fidel.metaData = jsonMetaData

You would receive a JSONObject that is equal to this one, after successfully enrolling a card, in the onResult callback, in the EnrollmentResult object.

bannerImage: Bitmap?

Default value: null.

Will display the banner image that you set in this parameter at the top of the card details screen.

The banner image will take the device's width, but it has a fixed height of 100 dp. The image view has the android:scaleType="centerCrop" attribute, which means that the banner image that you set will fill its entire predefined area.

For the banner image that you can set, we suggest to use the aspect ratio of the smallest devices that you support. On wider devices, the banner image will be cropped from top and bottom sides. This is because of the android:scaleType="centerCrop" attribute that we set for the image view.

If a device that opens the SDK has 320dp in width, the aspect ratio of the image view would be 320 : 100. If a device that opens the SDK has 475dp in width, the aspect ratio of your banner image would be 475 : 100.

You need to provide the image for all screen densities.

Depending on what you want to display in the banner image, you might need to experiment a bit to make sure that nothing important from the image is hidden. The most important information should be displayed in the centre of the banner image.

programName: String

Default value: "our"

This value is used in the consent text when enrolling a card issued in a United States or Canada.

programType: ProgramType

Default value: ProgramType.TRANSACTION_SELECT

It specifies the type of program you want to enroll cards into. The ProgramType influences the flow that the SDK will show to cardholders when enrolling cards.

Note: For your Loyalty application, you need to use a Transaction Select program, so you can either explicitly set the value to TRANSACTION_SELECT or not set this property (because its default value is TRANSACTION_SELECT).

thirdPartyVerificationChoice: Boolean

Default value: false.

Not useful for Loyalty/Select Transactions use cases, at the moment.

Methods

start(context: Context)

Starts a card enrollment flow. If you set the programType to:

  1. TRANSACTION_STREAM, a card enrollment flow will be started, for a Transaction Stream program (usually used by Stream applications).
  2. TRANSACTION_SELECT, a regular card enrollment flow will be started, for your Transaction Select program (usually used by Loyalty applications).

Parameters

  • context: Context: the Context that will start the card enrollment flow. This is a mandatory parameter.

verifyCard(context: Context, cardVerificationConfiguration: CardVerificationConfiguration)

Not useful for Loyalty/Select Transactions use cases, at the moment.

onMainActivityCreate(context: Context)

Not useful for Loyalty/Select Transactions use cases, at the moment.

Callbacks

The SDK provides the following callbacks:

onResult: OnResultObserver

The OnResultObserver interface has a single function.

12
fun onResultAvailable(result: FidelResult)

It will be called when a FidelResult is available, during the card enrollment process. It can be called multiple times with different types of results.

sealed class FidelResult

Types of results:

  • Enrollment(val enrollmentResult: EnrollmentResult): Received after successfully enrolling the card in your Fidel API program. Please find details about EnrollmentResult below.
  • Verification(val verificationResult: VerificationResult).Not useful for Loyalty/Select Transactions use cases, at the moment.
  • Error(val error: FidelError). An error occurred either during the card enrollment process. Please find details about FidelError below.

data class EnrollmentResult
