To locate the device certificate’s serial number, you have two options:

 

1.** Response of createSigner endpoint**: The serial_number is included in the response when you use the createSigner endpoint.

 

2.** fiskaly Dashboard**: You can also find the serial number by navigating to the fiskaly Dashboard. Once there, go to the Spain section and select Signers. The serial number will be listed alongside the Signer.
