-Format of the Wallet Instance Attestation Request
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Wallet Instance Attestation Request
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 To obtain a Wallet Instance Attestation from the Wallet
 Provider it is necessary to send a Wallet Instance Attestation
 Request from the Wallet Instance containing the associated public key
 , the ``nonce`` value previously requested and a ``jti`` value.
 
-Header
-^^^^^^
+The Wallet Instance MUST do an HTTP request to the Wallet Provider `token endpoint`_,
+using the method `POST <https://datatracker.ietf.org/doc/html/rfc6749#section-3.2>`__.
+
+The **token** endpoint (as defined in `RFC 7523 section 4`_) requires the following parameters 
+encoded in ``application/x-www-form-urlencoded`` format:
+
+* ``grant_type`` set to ``urn:ietf:params:oauth:grant-type:jwt-bearer``;
+* ``assertion`` containing the signed JWT defined in the Section `Wallet Instance Attestation Request`_.
+
+Below a non-normative example of the HTTP request.
