Thank you for the contact.
my tool basically sends msgs via whatsapp to my user's customer data, so it would be an example. Joao has an online store and has a lot of abandoned cart, joao integrates my tool into his store, so my tool takes data from joao's store like: amandonado cart - customer's name, phone, product that interested him, etc. .. and with this data, joao can create messages inside my tool and schedule them to be sent automatically, thus increasing the chance of converting this potential customer.
there are already tools that do this and that deliver with various ecommerce platforms, I already have integration with woocomerce and I want to expand the tool for shopify...
however I am having trouble creating an api that would do this integration with shopify users, there is a website that basically does what I want to create, but when I do the integration it shows me that this tool was not approved by shopify but it does the integration in myself, I want to know how it can be done
