share-disabled
403 — share-link creation is turned off for this shop.
https://docs.getenvie.com/errors/share-disabled · 403 — the merchant disabled wishlist sharing, and something called POST /v1/storefront/wishlist/share anyway.
What to do with it
Don't show a share button the shop has turned off: GET /v1/storefront/config returns
shareEnabled, and <envie-share> already hides itself (reflected hidden attribute) when
sharing is off.
Existing share links keep resolving read-only or stop, per the merchant's setting at read time — your integration doesn't need to handle that beyond the normal not-found case.
The setting lives in the merchant's admin under Envie → Settings.
