A Merchant ID identifies you as a merchant who can accept payments via Apple Pay.
  1. Sign in to your Apple Developer Account.
  2. Go to Certificates, Identifiers & Profiles > Identifiers.

  5. Enter a description and a unique identifier (e.g. merchant.com.example.yourbusiness).

2. Verify Your Domain

Apple requires your domain to be verified before Apple Pay can be used on it.
  1. Go back to your Merchant ID page in the developer portal.

  3. Enter the domain name (e.g. example.com).
  4. Download the Apple Pay Verification File (apple-developer-merchantid-domain-association).
