Sending Dynamic Query string based on the locale to the oAuth technical profile authorization endpoint

[ihabdamen]

Hi All

We are working in a project using AAD B2C where we have a custom identity provider to integrate with, we are integrating with it using the OAuth2.0 technical provider. The identity provider authorization endpoint support two language (English and Arabic)

We need to send a query string called (ui_locales) to the authorization endpoint with the current local (en or ar) to allow the page to be loaded with the correct language.

Is there a way to achieve this from the OAuth 2 technical profile?

Many Thanks
