The client makesa call to theendpoint / authorize of the IN,
providing its client_id andits callback url asparameters.
The client makesa call tothis API todisconnect the user, by
providing set the user'saccess_token
The client makesa call tothis API toretrieve user data,
providing the user'saccess_token as aparameter
The client makesa call toretrieve the access_token and the
id_token, providing the authorization code received during
the 1strequest as aparameter.
After authenticating (1FA and 2FA), the user
is redirected to
the partner site (customer) via a 302 redirection. An
authorization code is provided as aparameter of the URL
• Access_token : authorization token linked to the user to
accessthe variousresources & APIs of L’identité
Numérique
• ID_token: signedtoken containing the user'sidentity data
in the form of a JWT (
Json WebToken).
Return ofuser identity data and other information (claims)
requested / authorized in the form of a json response
Code 204, the useris loggedout

22. 2. User data recovery
2.1.Two methods to recover data - JWT
TheOpendIDConnectprotocol offered by L’Identité Numériqueallowsthe partner to
retrieve the identity data of theauthenticated user in theform of aJson WebToken.
The J WTis a signed token which means:
• That the data transmitted has not beenmodified
• That the data has beentransmitted by L’Identité Numérique
Two signature algorithms available HS256and RS256
.
Once decoded using tools or libraries available on the internet, the identity data and user
information are exposed in the J SON payload, as well as the token metadata
The La Poste public keyto verify the signature of the J WTis available at this address:
• Sandbox: https://integration.compte.laposte.fr/key/public.pem
• Production: https://compte.laposte.fr/key/public.pem
User datawill bethoserequestedin theclaims duringthe first call to theendpoint/

access_token.

Theseclaims canconstitute :
○ Theuser’s« pivot » identity data
○ Variousinformation about the user
○ Authentication context data
• At the start of the authentication sequence, whencalling GET to
/ authorize, the client mustspecify the claims they wish to
recover
• Thenumberand type of claimsrequested may be different in
the id_token and in the API
