Where is Google pay Developer account and how to generate public key to upload in it?

Question

No One on Whole of Stack overflow no one has answer to this, I dont know why , has no one worked with Google pay on android?? . According to google :

Follow this link :

https://developers.google.com/pay/api/android/guides/resources/payment-data-cryptography#key-rotation

it talks about key rotation which is mandatory when using DIRECT integration in your App , means if you are not using a payment processor directly/explicitly.

here is what it says :

Key rotation : If you decrypt a payment method token directly on your servers with direct integration, then you must rotate the keys annually.

To rotate encryption keys:

Use OpenSSL to generate a new key pair.

Open your Google Pay Developer Profile while signed in with the Google Account used to manage your app in Google Play Console Under the "Public encryption keys" section, select the Add an encryption key button. Then, select the "Public encryption key" text input field and add your newly generated public key Base64-encoded in uncompressed point format. Click Save.

See the screenshot below from the above link . Can any one click on this link and tell me why it takes you to support page instead of Google pay developer account ?

How to create a google pay developer account?

You need to sign up for production access: https://developers.google.com/pay/api/web/guides/test-and-deploy/request-prod-access

Do i need to pay?

No, you do not need to pay.

My company already has a google pay console account ( Where you manage and upload apps to goole play store )

The Google Pay Developer Profile is different from the Google Play developer console. If you don't have a Google Pay Developer profile you will need to sign up for one.

Where and how will i generate public key?

The following link provides details on how to generate a public key using OpenSSL: https://developers.google.com/pay/api/android/guides/resources/payment-data-cryptography#using-openssl

Important bits:

# generate private key
openssl ecparam -name prime256v1 -genkey -noout -out key.pem

# generate a base64-encoded public key
openssl ec -in key.pem -pubout -text -noout 2> /dev/null | grep "pub:" -A5 | sed 1d | xxd -r -p | base64 | paste -sd "\0" -

Where and how will i upload this public key in google pay developer profile?

The public key needs to be added to both the Google Pay Developer Profile and included as part of the payment request: https://developers.google.com/pay/api/android/reference/request-objects#direct

Note that you need to be registered with Google Pay for DIRECT integration.

Example:

"tokenizationSpecification": {
  "type": "DIRECT",
  "parameters": {
    "protocolVersion": "ECv2",
    "publicKey": "BOdoXP1aiNp.....kh3JUhiSZKHYF2Y="
  }
}

Can any one click on this link and tell me why it takes you to support page instead of Google pay developer account?

If you are logged in with a Google account with access to the Google Pay Developer Profile, you see the Google Pay Developer Profile details. If you are not logged in or do not have access to the profile you will be redirected to the support page.

You need to be signed into your Google Account which has access to the Google Pay Developer Profile.

EDIT: Corrected information about uploading the public key.

UPDATE: Google Pay has recently launched the Business Console to sign up and manage Google Pay integrations.
