General Questions

Shift4Shop (formerly 3dcart) migrations with Cart2Cart use the store REST API. Enable it in the Shift4Shop control panel before connecting the Migration Wizard.

1. Log in to your Shift4Shop (3dcart) admin.

Shift4Shop Admin Panel - Modules Section

2. Go to Modules (or Settings → Modules, depending on your theme/build).

Shift4Shop REST API Settings - Adding Public Key

3. Find REST API / Advanced API and open its settings.

Shift4Shop REST API Authorization for Cart2Cart

4. Enable the module / API access.

5. Create or copy the API credentials (token / key) the module displays.

6. Paste those credentials into the Cart2Cart Migration Wizard when prompted for Shift4Shop / 3dcart API details.

If your control panel still shows “3dcart” branding, the same Modules → REST/Advanced API path applies under the Shift4Shop product.
