Si vous allez sur les `/docs`, vous verrez que le champ `data` attend des octets encodés en base64 :

Vous pourriez envoyer une requête comme :

# Authentification HTTP Basic { #http-basic-auth }

Pour les cas les plus simples, vous pouvez utiliser l'authentification HTTP Basic.

Avec l'authentification HTTP Basic, l'application attend un en-tête contenant un nom d'utilisateur et un mot de passe.

Si elle ne le reçoit pas, elle renvoie une erreur HTTP 401 « Unauthorized ».

Et elle renvoie un en-tête `WWW-Authenticate` avec la valeur `Basic`, et un paramètre optionnel `realm`.
