Overview

Connect your K4G seller account to Keysender to automate order fulfillment and inventory management for K4G orders. K4G issues an App ID and Secret for the connection; once entered, paid K4G orders are delivered from the inventory you map and the K4G stock count follows your inventory. Apply at k4g.com/sell if you do not sell there yet.

TL;DR

  • Email K4G for an App ID and Secret, then add K4G under Integrations in Keysender with them.
  • Create and publish your offers in the K4G seller panel.
  • Refresh under Sale Channels, K4G in Keysender and assign each offer to an inventory.

Before you start

Make sure you have:

  • Access to your Keysender vendor account.
  • An active K4G seller account. If you do not have one, email [email protected] and ask to sell on K4G.
  • Your K4G App ID and Secret. Request these from K4G before you integrate.

To get your App ID and Secret, email [email protected] and ask for the API credentials needed to integrate with Keysender. Include your K4G account email. K4G can take a few business days to issue the credentials.

Steps

Add the K4G integration in Keysender

  1. Open Integrations in Keysender.
  2. Click + Add New.
  3. Select K4G from the dropdown.
  4. Enter a Store Name for your own reference.
  5. Enter the App ID and Secret provided by K4G.
  6. Click Save. Keysender generates an Access Token when the integration is saved.

Create your offers on K4G

  1. Log in to your K4G seller panel.
