WPML & Error code”: 422, “message”: “Unauthorized

Hello,

I encountered a problem and then I found a solution that could help other users. In the combination of WPML & Elementor Form & FluentSMTP and Outlook or Office 365 connection, sending emails from the web form only works on the original domain and language, if the other languages ​​are in the directories. If you try to send a request via the web form in other languages, you will get an error:

"code": 422,
"message": "Unauthorized",
"errors": [
"Unauthorized"

The solution to the problem is to add paths for each language in the Microsoft Entra admin center:

Home > Enerprise application > All applications > FluentSMTP domain.com | Properties > App registrations > FluentSMTP domain.com

Under "Authentication" Web - Redirect URLs, you should add the other languages ​​in addition to the basic domain in the main language. For example:

https://domain.com/wp-json/fluent-smtp/outlook_callback (main language - original record)

https://domain.com/it/wp-json/fluent-smtp/outlook_callback (Italian language)

https://domain.com/de/wp-json/fluent-smtp/outlook_callback (German language)

etc...for all languages ​​used on the site.

I assume that the same problem occurs with all WP plugins for sending emails through forms that do not solve the path change for callback URLs themselves.

Best regards
