iOS SDK - User Enrollment Module

Use the endpoints of this module to create and manage a wallet user's profile, including contact information, login credentials, secret questions, etc.

Initialize User Enrollment Facade

Prior to invoking any user enrollment module endpoints:

  1. Create a new request object for the relevant coordinator.
  2. Implement the delegate for the coordinator to handle responses.
PDUserEnrollmentCoordinator *tempUserEnrollmentCoordinator = [[PDUserEnrollmentCoordinator alloc] init];
self.userEnrollmentCoordinator = tempUserEnrollmentCoordinator; [tempUserEnrollmentCoordinator release];

retrieveMfaQuestionsWithMetadata

Gets the set of multi-factor authentication (MFA) questions and requirements configured for the wallet by its issuer.

Note: If the enrollment is canceled or expires before completion but after MFA questions are retrieved, you must clear the retrieved questions from the app's memory cache. Since registration was not completed, the user is not logged in and the cache-clearing that you implement as a logout step is not invoked. If enrollment is abandoned prior to MFA retrieval, no action is required. Likewise, if MFA retrieval is invoked after login (such as for secret question reset), proper logout cache-clearing is sufficient.

Element Value
Method Signature -(void) retrieveMfaQuestionsWithMetadata;
Success void (^RetrieveMFAQuestionsWithMetadataCompletionBlock)(PDRetrieveMFAQuestionsWithMetadataResponse*response);

response - Contains the set of MFA questions available for selection as secondary authentication questions. Depending on the issuer configuration, the questions may be returned as a set of strings or as a set of PDMFAQuestionWithMetadata that also specify requirements, such as the number of questions the user must answer, whether any questions are mandatory, etc.
Failure void (^RetrieveMFAQuestionsWithMetadataFailureBlock)(PDPaydiantError*userEnrollmentError);

Configure user error messages for this call with the key kUserErrorFetchMfaQuestionsWithMetadataDomain.

Error Description
500 An unknown error occurred internally in the server.

retrievePasswordConfigurations

Gets the issuer-defined requirements for the user password, such as minimum length, capitals, lowercase, numbers, symbols, etc.

Note: It is the app's responsibility to validate the password field input based on the requirements returned in this call. Registration will fail if the password set does not meet the issuer's requirements.

Element Value
Method Signature -(void) retrievePasswordConfigurations;
Success void (^RetrievePasswordConfigurationsCompletionBlock)(PDUserPasswordConfigurations*passwordConfigs);

passwordConfigs - The complete set of password validation rules as defined during issuer onboarding.
Failure void (^RetrievePasswordConfigurationsFailureBlock)(PDPaydiantError*userEnrollmentError);

Configure user error messages for this call with the key kUserErrorRetrievePasswordConfigsDomain.

Error Description
500 An unknown error occurred internally in the server.

retrievePasscodeConfigurations

Gets the issuer-defined requirements for the user PIN, such as minimum length.

Note: The app must validate the PIN field input based on the requirements returned in this call. Registration will fail if the PIN set does not meet the issuer's requirements.

Element Value
Method Signature -(void) retrievePasscodeConfigurations;
Success void (^RetrievePasscodeConfigurationsCompletionBlock)(PDUserPasscodeConfigurations*passcodeConfigurations);

Success void (^RegisterUserCompletionBlock)(PDRegisterUserResponse*response);

response - Contains the newly created user profile, plus status information related to the outcome of the call and a temporary nonce that, when passed with the loginByNonce method within the time period configured by the issuer, allows the app to automatically log the user in without requiring the user to re-enter credentials.

500 An unknown error occurred internally in the server.

registerCustomer (SSO)

Registers a new wallet for a user where the profile is managed and authenticated by an external system repository, such as the issuer's existing user database or a third-party identity provider (IDP).

Note: Before invoking registration, call retrieveCustomerProfileMetaData to obtain the profile properties relevant to the external repository and a one-time session token required to call that system.

Element Value
Method Signature -(void)registerCustomer:(PDRegisterCustomerRequest*)request;

request - Passes a new user profile populated with profile data and the nonce returned in the retrieveCustomerProfileMetaData response.
Success void (^RegisterCustomerCompletionBlock)(PDRegisterCustomerResponse*response);

updateUserProfile

Submits changes to one or more properties of the user profile on record, observing the conventions defined below.

Note: If email verification in enabled by the issuer, updating the email address value triggers an email to the new address containing a verification link and a notification email to the prior address on record. The new address will not be activated until verification is completed.

Method Overview

Updates to additionalCustomerInformation values are applied according to the following conventions:

  • Properties that specify a value in the update object are modified with the new value. If the new value is the same as the existing value, the ModifiedDate still reflects that the property was changed.
  • Properties that are omitted from the request remain unchanged.
  • Properties that are included in the object with a null value are deleted from the record.

Updates to MFA question selection and/or responses on record are applied according to the following conventions:

  • The app must populate the mfaAnswers attribute of PDUserProfile with the exact number of required MFA question/answer values, as specified in the PDRetrieveMFAQuestionsWithMetadataResponse returned in the retrieveMFAQuestionsWithMetadata call.
  • If the mfaAnswers attribute contains fewer or more than the specified required value, the update operation will fail.
  • Once updated, previously selected question/answer values are deleted from the profile.

If the externalId attribute is defined for the profile, the updated PDUserProfile object must be populated with the same value. Otherwise, the value will be deleted.
