   curl --location --request POST 'http://127.0.0.1:8000/api/token/' \
   --header 'Content-Type: application/json' \
   --data'{
   "email": "email",
   "password": "password"
   }'

2. retrieve access token and refresh token

   {
   "refresh": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoicmVmcmVzaCIsImV4cCI6MTYyOTAwMDU1MywianRpIjoiMTc4MjMzZjBjZmY1NGIyNmIxZjRjNzJiYzZjMTI1ZmIiLCJ1c2VyX2lkIjoxNDczMjAyNjg3MzU1OTEyMTk0fQ.tzUPzWf0YTGzz7np9Pn6P_pmTkADioZZHaMuLpzbDcA",
   "access": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwiZXhwIjoxNjI4OTE0NDUzLCJqdGkiOiJmOTdmNzM2NmI2OTE0MzdlOWIxMDljMDhjNGFhZTJmYyIsInVzZXJfaWQiOjE0NzMyMDI2ODczNTU5MTIxOTR9.Nvcn420emlxgT_tIyqQXaFu84npe9XVVTZO9UL-RAqY"
   }

3. verify access token with header Authorization: Token <access-token>

   curl --location --request GET 'http://127.0.0.1:8000/api/sponsors' \
   --header 'Authorization: Token eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwiZXhwIjoxNjI4OTA4Njc2LCJqdGkiOiI0YWJkNjY1ZTUyMTI0ZWE0YmQxM2Y4MmNkMDFlOGQ1YyIsInVzZXJfaWQiOjE0NzMyMDI2ODczNTU5MTIxOTR9.sTVkLAAfNKNyit6kwB069czVbYEqQtIwFSp7zZHVrUk' 

access token has expired ↓↓↓

{
    "detail": "Given token not valid for any token type",
    "code": "token_not_valid",
    "messages": [
        {
            "token_class": "AccessToken",
            "token_type": "access",
            "message": "Token is invalid or expired"
        }
    ]
}

refresh token has expired

{
    "detail": "Token is invalid or expired",
    "code": "token_not_valid"
}

---

Refresh an expired access token

1. send GET request to api/token/refresh/ to refresh access token

   curl --location --request POST 'http://127.0.0.1:8000/api/token/refresh/' \
   --header 'Content-Type: application/json' \
   --data '{
   "refresh": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoicmVmcmVzaCIsImV4cCI6MTYyODk5MDQyNCwianRpIjoiOWQyZjdjYjFmOTkxNDExNDg0NzU5MTFhZTNhYmU2ZjAiLCJ1c2VyX2lkIjoxNDczMjAyNjg3MzU1OTEyMTk0fQ.i7hNgCJQ3taPkBj8f7fA4y0enC32Ff_t52q3PV3um_0"
   }'

   response

   {
   "access": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwiZXhwIjoxNjI4OTE0NzQ4LCJqdGkiOiI4Y2IyNTM1OTAwZDE0NmRjOTUwN2YwNTUzMjM0ZDI4NiIsInVzZXJfaWQiOjE0NzMyMDI2ODczNTU5MTIxOTR9.HwYx-me_X7jwMMVOsB8d9Fd_bn3gYayoPetMo_JrMCo"
   }

Expected behavior

• call api/token/ to retrieve access token and refresh token
• call api/token/refresh to refresh access token when expired
• the access token is expected to expire after 5 mins
• the refresh token is expected to expire after 1 day
