Step-by-step guide

1

Open JTL-Shop Admin

Go to https://your-shop.com/admin and log in as administrator.

2

Enable REST API

The REST API is built in to JTL-Shop 5 but must be manually enabled. Open the JTL-Shop configuration file or enable the API via the shop settings.

The REST API is currently in beta. In future JTL-Shop versions it will likely be enabled by default. See the official JTL documentation at guide.jtl-software.de for activation details.
3

Open API settings

After activation you will find the API settings in the JTL-Shop Admin.

4

Generate API key

In the API settings, create a new API key.

Copy the generated key and store it securely.

Depending on configuration you can create multiple API keys and assign them different permissions.
5

Enter in ProductPolish

Go in ProductPolish to Dashboard→Integrations→New connection.

  1. Select JTL-Shop as the platform
  2. Enter your shop URL – without /admin
  3. Paste your API key
  4. Click "Save connection"
Done! ProductPolish can now create and edit products in your JTL-Shop via the REST API.

Good to know

  • JTL-Wawi sync: Products created via the API are automatically transferred to Wawi at the next sync.
  • JTL-Shop 4: Not supported as JTL-Shop 4 has no REST API. Please upgrade to JTL-Shop 5 (at least version 5.4).
  • Beta status: The REST API in JTL-Shop 5 is still in beta. We recommend monitoring the JTL roadmap for production use.
  • Images: Product images are uploaded via the API and automatically assigned.
  • SEO: SEO fields (title, meta description, URL slug) are automatically populated.
