Lightspeed Retail (R-Series) API Connection

Lightspeed Retail (R-Series) API Connection

Lightspeed Retail (R-Series) uses an application authorization flow that returns the API Key required for the Source connection. If the edition is not yet confirmed, use the Lightspeed Overview to compare all supported Lightspeed editions before continuing.

Get the connection details

1. Sign in to the intended Lightspeed Retail (R-Series) administrator account.
2. Open the NC-Migration authorization link.
3. Click Authorize Application to authorize NC-Migration.
4. Download the generated lightspeed_api_key.txt file.
5. Open the file and record the API key.

Enter the values in Next-Cart

Next-Cart field	Value to enter

R-Series has no Source Store URL field

Do not add or substitute a Source Store URL for this edition. Store identity behavior for no-URL Source setups is governed by Store URL Locking and Store Identity.

Verify this connection

Use Test Platform Connections for optional access verification. A successful test shows Connected.

Check	Pass condition
Store or account identity	Authorization was completed with the intended Lightspeed Retail (R-Series) administrator account.
Credential or value	API Key is the value obtained for this same intended Lightspeed Retail (R-Series) store, account, or authorization setup.

A Connected result confirms that Next-Cart can access Lightspeed Retail (R-Series) with the supplied connection values. It does not confirm migration configuration, mappings, or final migrated data; validate those separately during the Configuration step and post-migration review.

If the platform remains Not connected, repeat authorization with the intended administrator account and confirm the downloaded API Key is the value entered in Next-Cart, then use the shared recovery checks.
