I have a few queries regarding a custom Shopify app I am developing:
- Is it possible to inject a UI element into a customer’s storefront using custom Shopify app?
- Can the order amount in the cart be updated when a customer selects to add loyalty points?
- Is it feasible to fire a webhook and make an external API call when a customer logs in to collect their loyalty point data?
I would greatly appreciate it if you could provide any relevant documentation or resources that can assist me in implementing these functionalities.
Thank you for your assistance.
Best regards
