I'm trying to generate Apple Wallet pass for one of my client but for some reasons related to Certificate signing I cannot generate a valid pass file. I've tried to use public key and private key for generating the Wallet pass but no success.
I might be missing the correct files here, can someone please guide me through the file generation process here?
There is no issue with my Web service to generate the .pkpass file by using an old certificate file (Issued by WWDR bak in 2020).
I'm using this pass file validator to validate the file.
