line_items
In this field you should enter the price id of a product you have created in stripe.
Your price id should look something like this: price_1PbaGKLpgKvw6WCMvjvexif
metadata[custom_value] (optional)
If you need to pass custom data through the checkout session you can do so by creating custom fields in the metadata, you can create as many as needed, all you have to do is replace "custom_value" with a name that makes sense for your use case.
When a response is returned from a checkout session, you will be able to access these custom values.
As an example, you might create a field called metadata[users_bubble_id], then when a checkout session is created you enter the current users id into this field. When the user completes a checkout session you will get a response and in that response under 'metadata', you will have access to the user id you entered.
