Linking codes are short-lived for security, so an old code may stop working.

Step-by-step fix

1. Generate a fresh linking code

In Peak PIM, go to Settings > Stores and generate a new linking code.

2. Use it right away

Copy the new code and paste it on the Shopify store you're connecting, immediately.

Still failing?

• Make sure Peak PIM is installed on the second Shopify store
• Confirm you are signed in to the correct Peak PIM account
