Error message

You can't gift your own product. To give it away for free, create a 100% off discount code under Checkout > Discounts and share the checkout link.

What it means

create_gift rejects a gift when buyer == product.user: a seller buying their own product can only ever be a test purchase, and test purchases were never built for gifts. The message names the supported alternative (a 100% off discount code) because the old internal-capability wording generated support tickets asking Gumroad to 'enable' test gifts.

Solutions

1. Create a 100% off discount code under Checkout > Discounts and share its checkout link with the recipient.
2. To exercise the gift flow end-to-end, purchase from a different, non-seller account.
3. Drop params[:gift] when making a seller test purchase.

Example fix

# before: seller account submits a gift purchase of its own product
params[:gift] = { giftee_email: 'friend@example.com' } # buyer == product.user

# after: self-purchases are test purchases; give the product away via a 100% off code instead
params.delete(:gift)

params.delete(:gift) if params[:gift].present? && buyer == product.user

def self_gift?(buyer, product, gift_params)
  gift_params.present? && buyer == product.user
end

begin
  Purchase::CreateService.new(product:, params:, buyer:).perform
rescue Purchase::PurchaseInvalid => e
  # message already contains the actionable guidance (100% off code); show it verbatim
  render_checkout_error(e.message) if e.message.start_with?("You can't gift your own product")
end

When it happens

Trigger: The authenticated buyer equals product.user and gift params are present (params[:gift] set, so is_gift? is true) when Purchase::CreateService#perform runs.

Common situations: Sellers testing the gift flow on their own product; creators trying to send their own product to a customer as a gift.
