CoreCommerce API Connection

CoreCommerce API Connection

A valid CoreCommerce API connection gives Next-Cart the authorized platform access required by the selected migration path.

Next-Cart may ask for CoreCommerce API credentials so it can access the supported data needed for migration. Prepare the values in CoreCommerce first, then enter them in the Next-Cart connection setup screen.

Use only the setup shown in Next-Cart

Follow this guide only when the Next-Cart interface asks for CoreCommerce API credentials. Do not use API setup as a substitute for another setup path shown for your migration path.

When to use this guide

Use this guide when:

• CoreCommerce is the Source Platform or Target Platform in your selected migration path;
• Next-Cart shows API setup for CoreCommerce;
• you have permission to enable API access and create external access keys in CoreCommerce.

Prerequisites

Before you begin, confirm that:

Requirement	Why it matters
CoreCommerce admin access	You need access to settings where API access and external keys are managed.
Permission to enable API access	API access may need to be enabled before credentials can be used.
Permission to create external access keys	Next-Cart may require a generated API Key.
Data scope is known	The credential must support the data types included in the migration scope.
Credential storage is secure	API credentials should be copied once and stored safely until setup is complete.

Required values

Required value	Where to prepare it	Notes
API Username	CoreCommerce API Settings	The username may be shown after API access is enabled.
API Key	CoreCommerce External Access Keys	Generate a new key for the migration service setup.

Set up CoreCommerce API credentials

1. Sign in to the CoreCommerce Admin Dashboard.
2. Go to Settings.
3. Open API Settings.
4. Enable API access if it is not already enabled.
5. Note the API Username shown in the API Settings area.
6. Save the API Settings page.
7. Under Settings, open External Access Keys.
8. Create a new external access key.
9. Use a clear name, such as Next-Cart Migration.
10. Save the key.
11. Copy the generated API Key and store it securely.

Enter the values in Next-Cart

In the Next-Cart connection setup screen for CoreCommerce, enter the values requested by the interface.

Next-Cart field	CoreCommerce value
API Username	API Username from CoreCommerce API Settings.
API Key	Generated key from External Access Keys.

Expected result

The CoreCommerce API values are ready to test in Next-Cart.

Verify the connection

After entering the values, run the connection test in Next-Cart.

Check	Pass condition
Authentication	The API Username and API Key are accepted.
Permission access	Next-Cart can access the data types required for the migration scope.
Environment	The credentials belong to the intended CoreCommerce store.
Data preview	If a preview is available, sample Products, Customers, or Orders can be read.

If the connection fails

Issue	What to check
Authentication error	Re-copy the API Username and API Key. Check for extra spaces.
API disabled	Return to CoreCommerce API Settings and confirm API access is enabled.
Missing permission	Confirm the admin account can enable API access and create external access keys.
Wrong store	Confirm the credentials were created in the CoreCommerce store used for the selected migration path.
Key no longer works	Create a fresh external access key and replace the value in Next-Cart.

Security cleanup

After migration work is complete and verified:

• remove or disable the external access key if it is no longer needed;
• keep only the credential records required for support or audit purposes;
• rotate any temporary admin password used to create the key.
