Product added to "Checkout" through API is not persisting

MalipetekMalipetek Member Posts: 5

Hello API team,

I have developed a solution for a client. On checkout page our script sends "checkout id" to our back end, and then our back end makes a POST request to API to add a specific product to checkout.

This functionality used to work. However it started not working. I inspected situation and concluded this is happening. When we send the request it indeed adds the product to "checkout". However when ever anything else is updated, email, shipment method etc. the product is removed.

I am unable to fix this issue. Can someone assist me or point me to a document which would explain why some products would not persist in "checkout" entity.

    Hi @Malipetek, Could you could share an example of a payload (including URL) that would lead to a product being subsequently removed from the checkout, this would be helpful in diagnosing. Could you also PM me the shopID and variantID of any affected products so I can look into this?

    After a long search I found out why it went wrong in the checkout that was because the product you wanted to add the “delivery tip” was a hidden product. It is not possible to work with hidden products hidden is hidden, so they cannot be bought at first. You can add the product to the checkout(via API) but when the checkout is refreshed it recognizes that the product is hidden and it is removed. You can test this easily by set the product(24357492) to visible and test it again.

    I hope this helps.
