Seller ID, Merchant Key and Seller Identifier

Seller ID

Your Google Wallet Seller ID is a unique, numeric code assigned to your business by Google.

Merchant Key

Your Merchant Key is a unique code that helps secure your communications with Google. Both you and Google will use this key to authenticate and verify the integrity of any messages you exchange. You'll need your key to use the Google Wallet for digital goods API.

For your security, we strongly recommend that you do not share your Merchant Key with anyone.
