Error message

Cannot create a transaction or open a checkout as no default payment link has been set for this account. Set in the Paddle dashboard, then try again.

Common causes

• All accounts need a default payment link to create a transaction or open a checkout, and none has been set for this account.

Troubleshooting

• Set a default payment link in the Paddle dashboard.
• For sandbox accounts, go to checkout settings. This can be any domain, including localhost.
• For live accounts, go to checkout settings. You must use an approved domain.
