How can my customers log in and see the licenses they have ? (Authentication, Personal token)

Hi all,
I am working on a third web client with angular to enable my customers to renew their licenses.
How can they log in ?
I am using this endpoint : https://api.cryptlex.com/v3/accounts/login
but it is keep sending me 400 Bad request

Hi,

It must also be sending a response json, which should contain the error message.

it is ok now I corrected it.
