+
+    """Token issuing endpoint.
+
+    The token endpoint is used by the client to obtain an access token by
+    presenting its authorization grant or refresh token.  The token
+    endpoint is used with every authorization grant except for the
+    implicit grant type (since an access token is issued directly).
+
+    The means through which the client obtains the location of the token
+    endpoint are beyond the scope of this specification, but the location
+    is typically provided in the service documentation.
+
+    The endpoint URI MAY include an "application/x-www-form-urlencoded"
+    formatted (per `Appendix B`_) query component,
+    which MUST be retained when adding additional query parameters.  The
+    endpoint URI MUST NOT include a fragment component::
+
+        https://example.com/path?query=component             # OK
+        https://example.com/path?query=component#fragment    # Not OK
+
+    Since requests to the token endpoint result in the transmission of
+    clear-text credentials (in the HTTP request and response), the
+    authorization server MUST require the use of TLS as described in
+    Section 1.6 when sending requests to the token endpoint::
+
+        # We will deny any request which URI schema is not with https
+
+    The client MUST use the HTTP "POST" method when making access token
+    requests::
+
+        # HTTP method is currently not enforced
+
+    Parameters sent without a value MUST be treated as if they were
+    omitted from the request.  The authorization server MUST ignore
+    unrecognized request parameters.  Request and response parameters
+    MUST NOT be included more than once::
+
+        # Delegated to each grant type.
