OP
I try to connect Lovable to my existing webshop in Shopify, but fails every time. Shopify Support has confirmed that the Lovable app is correctly installed on my store and the access token is valid. They verified a successful Admin API request was made on 2025-12-02 19:46:28 UTC. However, the Lovable interface continues to show a persistence_failed error during the OAuth flow, preventing the integration from completing. This suggests the issue is on Lovable's side with storing/recognizing the OAuth token, not with Shopify. Can anybody help me?
