Hi! Not directly possible, but you could use line_items.adjustable_quantity to add an extra line item for the tip. https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-line_items-adjustable_quantity

Ok, Does adding the extra line item require the secret key?

Wait, are you using the client-only Checkout? If so, adjustable_quantity probably won't work.

Any alternatives using publishable?
