# InvoicePaymentLinkNotIssuedReason

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

Why an invoice went out with no payment link. Recorded on the invoice's activity timeline so an
operator can tell a misconfiguration from a merchant that simply has no hosted page, without
reading host logs.

## Values

| Value | Description |
| --- | --- |
| `NothingPayable` | The invoice has nothing left to pay. |
| `BillerNotMerchant` | The invoice is not billed by a merchant, so hosted-page ownership cannot be confirmed. |
| `NoDefaultHostedPage` | The invoice names no hosted page and the merchant has no active payment page to default to. |
| `AmbiguousDefaultHostedPage` | The invoice names no hosted page and the merchant has more than one active payment page. |
| `NoPermittedPaymentMethod` | Every payment method the invoice allows is turned off for the merchant. |
| `HostedPageNotFound` | The hosted page the invoice targets was not found for the invoice's merchant. Covers a deleted page and a page that belongs to another merchant alike, by design. |
| `HostedPageInactive` | The hosted page the invoice targets is inactive. |
| `SessionRejected` | The hosted page refused the payment session for another reason; the metadata carries the stable error code. |
