How to use?

At first, you have to create your account.

curl -X https://mailway.com/api/users/register
    -H "Content-Type: application/json" \
    -d '{
        "username": "Gumar",
        "password": "Somepassword2134123"
    }'

Then get your access token:

curl -X https://mailway.com/api/users/login
    -H "Content-Type: application/json" \
    -d '{
        "username": "Gumar",
        "password": "Somepassword2134123"
    }'

You will get a JSON like this:

{"data":{"created_at":"2026-01-05T12:21:57.240362177Z","expires_at":"2026-01-06T12:21:57.240362104Z","token":"ARandomTokeJWTTokennassdfasdfs8e8i8","username":"creator"},"message":"token generated"}
