Decoding a user access token generated by Firebase

Kris Jack

Hello all,

I'm using Firebase for user management and Xano for all other backend functionality.

I am failing to decode a Firebase access token in Xano.

• created function Security -> JWS Decode
• set the token to a valid token generated by Firebase
• set the key to be an object with path and value found via Firebase (https://www.googleapis.com/robot/v1/metadata/x509/securetoken@system.gserviceaccount.com)
• set the signature_algorithm to be RS256

When I run the function, it fails, giving the error 'Invalid key format.'.

Can anyone please help?

Best,

Kris
