Guide Overview

We will link NP deferred payment with Sanka and prepare to start synchronizing company and order data.

Advance preparation

  • NP deferred payment contract is valid and Merchant Code, SP Code, and Terminal ID have been obtained.
  • Privilege for linkage settings in Sanka's workspace
  • Registration policy for basic information (company name, address, telephone, email) used for collaboration target companies/orders has been decided.

Step 1. Open the linked service screen

  1. Open the target workspace in Sanka.
  2. Open Cooperation Service from Workspace.

Step 2. Add NP deferred payment

  1. Open the Add Linkage Service screen.
  2. Select NP deferred payment from the list.

Step 3. Enter merchant information and save

  1. Enter the Merchant Code, SP Code, and Terminal ID that you confirmed on the NP deferred payment management screen.
  2. If you are connecting in a test environment, check Staging environment.
  3. Click Update to save.

Step 4. Check the connection

  1. Confirm that NP deferred payment is displayed in the list of linked services.
  2. If an error occurs, check the code for typos and the environment (production /staging).

Step 5. Operational points

  • It is safe to try a small amount of data in a staging environment before production operation.
  • First, determine only the minimum necessary items for companies and orders, and add them according to the operation.
  • If the connection fails, please check whether the issuing information on the NP postpaid side is up to date.
  • If company or order sync fails after setup, review the required fields in NP Payment field mapping.
