How can I 'inject' a cart line 'custom product' via Hydrogen Shopify

[rattlesnakeMT]

I'm trying to brainstorm my way around this problem. I thought doing this as a draft order was the way, but doesn't look like you can add that as a cart item.

So backing up, I'm trying to create bundle handling. I have two (or more) products with many variants, and I have builders managing attributes and the variants. The problem is that I cannot create a bundle via the Bundle API, because the variants and option counts exceed the limits.

What I want to do is create my own bundle handling via the product builder I have currently working. I want to bundle them (and discount appropriately) and then add the completed bundle item to the cart as a single cart item (you can't remove a particular item of the bundle), you'd have to remove the entire bundle. So there is some heavy lifting that needs to be done - calculating pricing, grabbing the variants/attributes, and inserting single cart line.

Thanks!

You can add arbitrary custom items to draft orders, if your running your own stack present a set of line items however you want then redirect to the draft-order checkout url that will just have the custom line items to represent the merchandise.

Fixed dundles have a 30 component limit and custom bundles a 150 component limit

If your exceeding both the information architecture is probably foundationally flawed.

If the bundle apis don't work for a self prescribed solution use a different approach: https://xyproblem.info/ 

Just create one off products for the customer and reconcile inventory, etc on the backend.

Beyond that there is a lack of detail no one can get past, lower the effort contributors need to understand or see the problem.
