Je souhaiterais intégrer la nouvelle API Ecowatt ([Catalogue API - API Data RTE](https://data.rte-france.com/catalog/-/api/doc/user-guide/Ecowatt/4.0)) dans Gladys.  
Cette API est accessible via un bearer token éphémère qu’il faut renouveler toutes les 2 heures.

En passant par Node-red on peut récupérer le token grâce à une requête http, puis réinjecter manuellement ce token dans une nouvelle requête http pour obtenir le payload de l’API.  
Cette solution marche bien mais n’est pas très pratique !

J’ai donc cherché (sans succès) une solution pour automatiser cette 2ième requête en injectant une variable correspondant au token actualisé toutes les 2 heures.  
Je pense qu’il faut passer par une fonction mais je n’arrive pas à fournir les bons headers de la requête.

Si un spécialiste Node-red a la solution, je suis preneur.  
Merci d’avance.

C’est une authentification oauth2, y’a des palettes pour gérer ce protocole.

EDIT: Je viens de tester ça avec succès
