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.
