Sandbox

The sandbox is a LINE Pay server where you can test the LINE Pay API if you are considering implementing LINE Pay or adding new features to a service already running with LINE Pay. Follow the steps below to create a sandbox account and use the sandbox API.

  1. Create a sandbox account
  2. Obtain credentials for the sandbox
  3. Test the sandbox API

Create a sandbox account​

In order to use the sandbox, you must first create a sandbox account. Click Apply for a sandbox account to create a sandbox account. You can only create one sandbox account per email address.

If you've already joined as a merchant, you can use sandbox without separate application. Skip to Obtain credentials for the sandbox.

Obtain credentials for the sandbox​

If you have created a sandbox account or joined as a merchant, you can request the necessary credentials to call the sandbox API from the merchant center. To obtain your credentials, follow these steps.

  1. Log in to the merchant center.

  2. Select [Payment Integration Management > Manage Link Key] from the menu on the left.

  3. Click the View button on the Manage Link Key page. A verification code will then be sent to the email you entered when you created your sandbox account (or joined as a merchant).

  4. In the Email verification window that appears, enter the verification code you received by email in the Verification code input field and click the Confirm button.

Once you complete these steps, you will see the channel ID and channel secret key as shown below. These values are entered in the request header when calling the Online API or Offline API, or used when generating the required values in the request header.

Test the sandbox API​

Once you have obtained credentials to call the sandbox API, refer to the following documents to call the sandbox API depending on the type of API you want to use.
