Once the transaction is created, the customer is redirected to the `return_url` you specified, or shown the page's own confirmation screen if you didn't set one. Gr4vy appends `gr4vy_transaction_id` and `gr4vy_transaction_status` to the `return_url`. The redirect happens for every transaction outcome, including declines, so check the status before you treat the order as paid. To confirm the result, [get the transaction](/reference/transactions/get-transaction) or listen for [transaction webhooks](/guides/features/webhooks/overview). ## Statuses The page displays different content based on the status of the payment link. ### Generic error Either the payment link id provided is invalid or some other error occurred when loading the page (for example network error). Generic Error ### Payment link not found The payment link id provided is valid but the resource associated with it could not be found. Not Found ### Redirecting Embed has created the transaction and the page is redirecting the customer to the `return_url` or the internal confirmation screen. Redirecting ### Payment successful (internal) The payment was successful and a `return_url` was not specified. Also displays if the payment link has already been used. Payment Successful ## Expiration By default, payment link expires in 24 hours. This can be configured separately by setting the `expires_at` field in the API. Once expired, a payment link no longer loads and instead shows the following screen.
