Apple Pay Payment certificate is not trusted

Question

I am working on implementing Apple Pay in my ios app, For that I tried to create certificates on the apple account.

I followed this setting_up_apple_pay_requirements link.

and followed the exectly these three steps

1.) Create a merchant ID.

2.)Create a Payment Processing certificate.

3.) Enable Apple Pay in Xcode.

But in my key chain when i added the created certificate, then it is showing "Apple Pay Payment Processing:"merchent id" certificate is not trusted"

Thanks in advance

Answer 1

I followed this trust error in key cain certificates

where it says "If you see a warning in Keychain Access that the certificate was signed by an unknown authority or that it has an invalid issuer, make sure you have the WWDR intermediate certificate - G2 and the Apple Root CA - G2 installed in your keychain. You can download them from apple.com/certificateauthority."

After downloading and adding "Worldwide Developer Relations - G2 Certificate " certificates into key chain. Now its is saying "This certificate is valid"

Download certificate from here
