Hosted checkout

Redirect customers to a Paysum-hosted checkout created from your own backend.

Hosted checkout lets you keep your own site or app while Paysum handles payment, receipts and delivery. You create a session server-side and redirect the customer to it.

Choosing what to sell #

Pass product_ids to sell products from your catalogue. Prices come from the product or variant, stock is enforced, and the order is delivered like any other store order.

{
  "product_ids": [
    {
      "id": "prod_123",
      "quantity": 1,
      "variant_name_or_id": "Lifetime"
    }
  ]
}

Session lifecycle #

Sessions start as pending and end as completed, cancelled or expired. They expire after 24 hours by default; set expires_in_seconds or expires_in_hours to change that, and expired_url to control where late visitors are sent.

Customising the page #

Use hide_navbar and hide_footer for a focused page, and disable_coupons or disable_gift_cards when the price must not change.

See Create session for every parameter.
