- How can you compare cart apps without two systems adding the same gift?
Assign one active owner to each reward during evaluation, inventory every system that can mutate the cart and compare candidates separately against the same test contract.
- How should a cart integration sequence gift updates and drawer refreshes?
Give cart changes an explicit sequence: settle the purchase change, reconcile the intended reward, render the resulting state and then allow the checkout handoff.
- What should a headless Shopify storefront verify before choosing a gift app?
A headless storefront needs a documented integration for the reward rule, cart mutations and checkout handoff; a theme widget or generic Shopify compatibility claim is insufficient evidence.
- Why should gift integrations target cart lines rather than product titles?
Use the current cart’s line identity to target the intended gift; product titles and remembered line keys are unsafe shortcuts when paid and promotional quantities coexist.
