Thank you for reading this post.

I am currently trying to call a "BOX" JWT authentication application from an OutSystems application via REST.

However, the following error occurs and I cannot call it.

Status Code BadRequest: {"error":"unauthorized_client","error_description":"The \"box_subject_type\" value is unauthorized for this client_id"}

Please refer to the attached image for the setting status.

I think I have set it up correctly, but I don't know why the error occurs.

I can't even guess where the cause is.

I checked the official reference, but I couldn't find a concrete solution.

If anyone knows the correct way to call the BOX API using an access token, please let me know.

Also, if there is a concrete reference on how to implement it, please let me know.

Can someone help me?

Thank you in advance.
