# Why am I getting an error saying I need to use a different store Public Token when connecting Shopify stores in Stock Sync?

This error appears when the Public Token you enter belongs to the **same Shopify store** you are trying to connect. In a Shopify‑to‑Shopify connection, the Public Token must come from the **source store**, and you must enter it in the **receiving store’s feed setup**.

If both stores are yours, double‑check that you copied the token from the correct store’s **Manage Account** page. Using the same store’s token will trigger the error. Once the receiving store uses the token of the correct source store, the connection will work.
