LINE Pay Developers

Channel ID & SK

You need a Channel ID and a Channel SecretKey for integration, and you can check them on Merchant Center after merchant registration.

- When a merchant links a payment through LINE Pay, LINE Pay uses the key value provided from this process for the second round of verification process.
※ These key values are unique and are not changed.

1. Email Verification

• 1) Click “View” button to search Channel ID and Secret Key.
  - Email verification pop-up will be displayed when you click 'View' button.

• 2) Email with verification code will be sent to merchant administrator’s email address. (For sandbox account, the email address of the Representative)
  ※ Since linking information is a security information, you need 2nd authentication.
• 3) Input verification code in pop-up screen and click 'Confirm' button.
  ※ Verification code is only valid for 10mins.
• 4) You can resend email code in case code is expired or you haven’t received email.
  ※ If you resend email, previous code will be expired and no longer able to use.
  ※ Page will be unavailable if you try too many failed attempts. (Max. 5times in 30mins)

2. Link key Search
