Note

In Azure Active Directory B2C, custom policies are designed primarily to address complex scenarios. For most scenarios, we recommend that you use built-in user flows. If you've not done so, learn about custom policy starter pack in Get started with custom policies in Active Directory B2C.

The Localization element allows you to support multiple locales or languages in the policy for the user journeys. The localization support in policies allows you to:

  • Set up the explicit list of the supported languages in a policy and pick a default language.
  • Provide language-specific strings and collections.
<Localization Enabled="true">
  <SupportedLanguages DefaultLanguage="en" MergeBehavior="ReplaceAll">
    <SupportedLanguage>en</SupportedLanguage>
    <SupportedLanguage>es</SupportedLanguage>
  </SupportedLanguages>
  <LocalizedResources Id="api.localaccountsignup.en">
  <LocalizedResources Id="api.localaccountsignup.es">
  ...

The Localization element contains the following attributes:

Attribute Required Description
Enabled No Possible values: true or false.

SupportedLanguages

The SupportedLanguages element contains the following attributes:

Attribute Required Description
DefaultLanguage Yes The language to be used as the default for localized resources.
MergeBehavior No An enumeration values of values that are merged together with any ClaimType present in a parent policy with the same identifier. Use this attribute when you overwrite a claim specified in base policy. Possible values: Append, Prepend, or ReplaceAll. The Append value specifies that the collection of data present should be appended to the end of the collection specified in the parent policy. The Prepend value specifies that the collection of data present should be added before the collection specified in the parent policy. The ReplaceAll value specifies that the collection of data defined in the parent policy should be ignored, using instead the data defined in the current policy.

Examples

ClaimsProvider

The ClaimsProvider value is used to localize one of the claim providers display name.

<OrchestrationStep Order="2" Type="ClaimsExchange">
  ...
  <ClaimsExchanges>
    <ClaimsExchange Id="FacebookExchange" TechnicalProfileReferenceId="Facebook-OAUTH" />
    <ClaimsExchange Id="GoogleExchange" TechnicalProfileReferenceId="Google-OAUTH" />
    <ClaimsExchange Id="LinkedInExchange" TechnicalProfileReferenceId="LinkedIn-OAUTH" />
  </ClaimsExchanges>

  <DisplayName>Email Address</DisplayName>
  <DataType>string</DataType>
  <UserHelpText>Email address that can be used to contact you.</UserHelpText>
  <UserInputType>TextBox</UserInputType>
</ClaimType>

The following example shows how to localize the DisplayName, UserHelpText, and PatternHelpText attributes of the email claim type.

<LocalizedString ElementType="ClaimType" ElementId="email" StringId="DisplayName">Email</LocalizedString>
<LocalizedString ElementType="ClaimType" ElementId="email" StringId="UserHelpText">Please enter your email</LocalizedString>
<LocalizedString ElementType="ClaimType" ElementId="email" StringId="PatternHelpText">Please enter a valid email address</LocalizedString>

ErrorMessage

The ErrorMessage value is used to localize one of the system error messages.

<TechnicalProfile Id="AAD-UserWriteUsingAlternativeSecurityId">
  <Metadata>
    <Item Key="RaiseErrorIfClaimsPrincipalAlreadyExists">true</Item>
    <Item Key="UserMessageIfClaimsPrincipalAlreadyExists">You are already registered, please press the back button and sign in instead.</Item>

  ...
</TechnicalProfile>

The following example shows how to localize the UserMessageIfClaimsPrincipalAlreadyExists error message.

<LocalizedString ElementType="ErrorMessage" StringId="UserMessageIfClaimsPrincipalAlreadyExists">The account you are trying to create already exists, please sign-in.</LocalizedString>

FormatLocalizedStringTransformationClaimType

The FormatLocalizedStringTransformationClaimType value is used to format claims into a localized string. For more information, see FormatLocalizedString claims transformation

  <InputClaims>
    <InputClaim ClaimTypeReferenceId="email" />
  </InputClaims>
  <InputParameters>
    <InputParameter Id="stringFormatId" DataType="string" Value="ResponseMessge_EmailExists" />
  </InputParameters>
  <OutputClaims>
    <OutputClaim ClaimTypeReferenceId="responseMsg" TransformationClaimType="outputClaim" />

<LocalizedString ElementType="Predicate" ElementId="Uppercase" StringId="HelpText">an uppercase letter</LocalizedString>

PredicateValidation

The PredicateValidation value is used to localize one of the PredicateValidation group error messages.

<PredicateValidations>
  <PredicateValidation Id="CustomPassword">
    <PredicateGroups>
      <PredicateGroup Id="LengthGroup">
        <PredicateReferences MatchAtLeast="1">
          <PredicateReference Id="LengthRange" />
        </PredicateReferences>
      </PredicateGroup>
      <PredicateGroup Id="CharacterClasses">
        <UserHelpText>The password must have at least 3 of the following:</UserHelpText>

          <PredicateReference Id="Number" />
          <PredicateReference Id="Symbol" />
        </PredicateReferences>
      </PredicateGroup>
    </PredicateGroups>
  </PredicateValidation>
</PredicateValidations>

The following example shows how to localize a predicate validation group help text.

<LocalizedString ElementType="PredicateValidation" ElementId="CustomPassword" StringId="CharacterClasses">The password must have at least 3 of the following:</LocalizedString>

UxElement

The UxElement value is used to localize one of the user interface elements. The following example shows how to localize the continue and cancel buttons.

<LocalizedString ElementType="UxElement" StringId="button_continue">Create new account</LocalizedString>
<LocalizedString ElementType="UxElement" StringId="button_cancel">Cancel</LocalizedString>

DisplayControl

The DisplayControl value is used to localize one of the display Control user interface elements. When enabled, the display control localizedStrings takes the precedence over some of the UxElement StringIDs like ver_but_send, ver_but_edit, ver_but_resend and ver_but_verify. The following example shows how to localize the send and verify buttons.

<LocalizedString ElementType="DisplayControl" ElementId="emailVerificationControl" StringId="but_send_code">Send verification code</LocalizedString>
<LocalizedString ElementType="DisplayControl" ElementId="emailVerificationControl" StringId="but_verify_code">Verify code</LocalizedString>

In the Metadata section of a self-asserted technical profile, the referenced ContentDefinition needs to have DataUri set to page layout version 2.1.0 or higher. For example:

<ContentDefinition Id="api.selfasserted">
  <DataUri>urn:com:microsoft:aad:b2c:elements:selfasserted:2.1.0</DataUri>
  ...
