Blocking checkout if only free products are added- shopify - shopify

We have a free product in our store, the product is supposed to be free if purchased with another product.
Are we able to stop a person checking out with just the free product?
Any help appreciated.

Shopify - custom price for each customer, calculate with external api

I would like to sell a few products on Shopify. The user should be able to select a product and fill a form. Then some of these values will be passed to an external API and the API returns the correct price. How to implement this in Shopify? Are there any Shopify apps that could support the development of this?
The development process has not yet begun, so I'm free to use any other shop builder out there.
There are some apps to make it possible so you can sell at different price for customers.
Shopify appstore app
Bold custom pricing
Wholesale pricing discount
But I don't think these apps will not perfectly satisfy your needs.
If I can suggest something, after customer fills a form and get a price, then you can make price of product show on the store, and at the same time you can make a request to change the price of that product by using Shopify product api. Then everytime customer comes to your store and buy products, the price will change and they will be able to purchage at different price. I think it will work.
In the end, I decided to use Stripe Checkout for this. The design is amazing and the setup is simple. Later I will most likely switch to Stripe.js and Stripe Elements to enable even more customization.

Shopify vendor product invoice emailer

Shopify billing api charges for sellers

New here and i hope i am in the right place to ask my question. We are having problem with submitting our app to Shopify App Store.
We have an app where people can create their own designs on our physical products and sell. So we can produce their products and dropship to their customers. There are many apps to that.
Problem is they forcing us to use Billing API for our product charges. They take 20% of commission which our margin is not that much. We are wholesaler and we our margin is super low. We use (well we were planing to use) Stripe for products charges, which is 2.9 % commission.
And Shopify Apps Team member is keep asking me my margin, and says: "We are requiring that all apps use the billing API, but I might be able to make an exception since it seems like your business model isn't compatible. If an exception is made, you will be required to sign a revenue share agreement based on your margins"
All other App (in our business line)they charge their customers with 3th party payment processors and i have spoken with some of them they say they never heard about it and they don't share any revenue (apart from membership fees) with Shopify.
Any idea about this?
Thank you so much for you help.
Shopify is charging 20% of the cost of the app not 20% of the cost of your finished products. I don't know if your app can be free and still in the app store but from what you have written free would work since you will actually make your money on the goods. Just bill normally for the orders you receive

Is there a way to tell what item someone purchased from your site through Product Advertising API?

Is it possible to see if a user purchased an item you've listed on your site?
I want to be able to keep track of items a user has purchased from amazon through my site. Is this possible?
i think this can be implemented using a remote shopping cart.

Ofcourse it will need some code on your end to relate a user in your site with a shopping cart id.

what are the must have functionalities for a web shop (shopping cart)

what are the must have functionalities for an e-commerce web shop?
e.g.
unlimited categories and sub categories
multiple categories per product
multiple product images
product consumer ratings and comments
payment gateway integration
delivery service integration
Best Sellers
Newest Products List
discount facilities
promotional facilities (buy one get one free)
I know we shouldn't just link to elsewhere, but this link is within stackoverflow. I'll just quote it all here:
Do you need to build one at all? Most of this has been done for you in
various shopping cart packages
including google checkout,
oscommerce, and others, but if
you must take the plunge try to at
least think about the following...
Secure session for users
Storing 'items' in the cart via the session / cookies
Payment processing
what external systems do you interface with
what kinds of payments do you accept
what currencies do you accept
Some kind of dispatching system for when a purchase occurs
If a purchase occurs, who is notified to mail out the items?
where is the purchase logged?
Interaction with an inventory system of some sort
is the item in stock?
what to do when out of stock?
Total / shipping calculations
how much do you charge shipping for different customers/destinations
where do you want to ship / where will you not ship
A shopping cart is far more complex a
concept than it appears to be. The
specific answer to these questions
will depend on what kind of
organization you are working for. Big
company? Small startup? Family
business? High volume vs low volume?
Etc.
