Hi @Rohit Joshi Our developer team has mentioned this can you kindly help us with this error
"Shopify has deprecated their Private Apps system and now requires a Custom App Access Token for API authentication. Our developer tested both the old Admin API key (which works) and the new Custom App token (which returns HTTP 401 Unauthorized). This suggests your Shopify integration is built on the old credential format and has not been updated to support Shopify's new Custom App authentication method. Can you update the integration to accept the new Admin API Access Token format from Custom Apps?"
