Pick-up points is one of the most popular shipping methods and a flexible delivery form where the customer can chose their own proffered delivery location. Showing pick-up points is a native part of the Smart Send app to Shopify, but Shopify requires you to have CarrierService activated on your Shopify account.
CarrierService is part of the Shopify Advanced subscription but can also be bought separately by contacting Shopifys support. Contact Shopify Support
Shopify charges 20€/month for CarrierService, if you do not have the advanced plan from them.
When you have activated Carrier Service you are good to go. Smart Send has including all other required services in our system, such as google maps api key to lookup closest pick-up point based on the address.
