# InvoicePaymentLinkState

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

Whether an invoice's payment link still opens the payment page, as reported by
`linkState`.

## Values

| Value | Description |
| --- | --- |
| `None` | The invoice carries no payment link. |
| `Live` | The link opens the payment page and accepts a payment. |
| `Expired` | The link's expiry has passed, so it no longer opens the payment page. |
| `Spent` | A payer's attempt used the link up. It no longer opens the payment page. A referral, a pending or submitted authorization and a partial approval always spend the link, because money may already have moved; a decline spends it once its retries run out, or at once when the link does not reopen after a decline. |
| `Revoked` | The link was withdrawn (revoked or cancelled) and no longer opens the payment page. |
