Hey @Grégory D ,
There is currently an Azure doc being written up and will be released as soon as possible,
Here is a small sample on how to do this using a b2c claims transformation policy,
Copies localized strings into claims.
| Item | TransformationClaimType | Data Type | Notes |
| OutputClaim | The name of the localized string | string | List of ClaimType that is produced after this ClaimsTransformation has been invoked. |
The following example looks up the email subject, body, your code message, and the signature of the email, from localized strings. These claims later used by custom email verification template. You first need to define a localization string and associate it with a self-asserted technical profile. The following code snippet defines the string collection for English (default) and Spanish. The
ElementType of the
LocalizedString element is a reference to your claims transformation Id (see following sample).
Then in the claims transformation you specify the list of claims ot be set with localized string. "ClaimTypeReferenceId" is a reference to a ClaimType already defined in the ClaimsSchema section in the policy. The "TransformationClaimType" is the name of the localized string as defined in the "StringId" of the "LocalizedString"
Please let us know if this is helpful, and keep a look out for the official document for further help.
