Invoices: Reads the invoice's pay-by-link state.
GET
/api/invoicing/invoices/{id}/payment-link
deprecated
Requires: Invoicing.Invoices, merchant scope.
Returns the absolute hosted-payment-page URL, when it lapses, the QR code URL and the backing session id. This read and the reissue below are the only endpoints that disclose the URL: it embeds a bearer credential, so it is deliberately absent from the invoice read and list payloads. The read never creates or rotates a link; re-send the invoice, or reissue the link, to mint a fresh one.
Example request
Every block below sends the same request. Replace {{BASE_URL}} with the address of the API you are calling and {{API_KEY}} with your own key.

Responses
200 The invoice's link state. An invoice with no payable link answers 200 with `hasPaymentLink` false rather than an error: sending without a link is a designed outcome (no resolvable hosted page, an ambiguous merchant default, a biller that is not a merchant, nothing payable, or every payment-method feature off), as is the invalidation that follows full payment.
Body: InvoicePaymentLinkInfoDto
Each item has these fields.
| Field | Type | Description |
|---|---|---|
invoiceId
required |
string (uuid) | The invoice the link pays. |
hasPaymentLink
required |
boolean | Whether the invoice currently carries a payment link at all. When `false`, every other link property is null and the invoice has no payable link to hand out. |
paymentUrl
required |
string | Absolute, HTTPS hosted-payment-page URL for the payer. Null when `hasPaymentLink` is `false`. nullable |
expiresAt
required |
string (date-time) | When the link stops working. Null when the invoice carries no link. nullable |
isExpired
required |
boolean | Whether `expiresAt` is already in the past. Computed server-side so the caller never has to compare against a client clock. Always `false` when there is no link. |
qrCodeUrl
required |
string | Public URL of the PNG QR code encoding `paymentUrl`. Null when the invoice has no link, or when QR generation was skipped or failed: generation is best-effort and never blocks a send, so a live link with no QR is a normal outcome rather than an error. nullable |
hppSessionId
required |
string (uuid) | The hosted-payment-page session backing the link. Null for an invoice with no link, and for a pre-cutover invoice still on the legacy opaque token. Safe to log and to quote in a support conversation, unlike the URL. nullable |
amountDue
required |
number (double) | Outstanding balance the link collects, in `currency`. |
currency
required |
string | ISO 4217 currency code of `amountDue`. nullable |
linkState
required |
all of InvoicePaymentLinkState | Whether the link still opens the payment page. `Spent` and `Revoked` come from the payment session behind the link; when that session cannot be read, the state falls back to `Live` or `Expired` from `expiresAt` alone. `None` exactly when `hasPaymentLink` is `false`. |
remainingDeclineRetries
required |
integer (int32) | How many more declined payment attempts the link can absorb and still reopen for the payer. Null when the link does not reopen after a decline, or when the payment session could not be read. nullable |
lastAttemptAt
required |
string (date-time) | When a payer last attempted a payment on the link: the attempt that spent it, or the most recent declined attempt the link reopened after. Null when no attempt is recorded, or when the payment session could not be read. nullable |

403 The host has no usable public base URL to build the link against (`WinkPG.Invoicing:PaymentLinkBaseUrlNotConfigured`). A platform misconfiguration rather than an authorization refusal; the status is the historical one this code has always answered with.

default The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. See the error-code reference in this document's description for the values `error.code` can take.

429 The request was refused because a rate limit was exceeded. Wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling.
Body: RateLimitProblemDetails
Each item has these fields.
| Field | Type | Description |
|---|---|---|
type
required |
string | The problem type identifier. Always the same value: the failure is the status code itself, so there is no sub-type for a caller to branch on. nullable |
title
required |
string | A short, human-readable summary of the problem type. nullable |
status
required |
integer (int32) | The HTTP status code, repeated in the body as the problem-details format defines. |
detail
required |
string | A human-readable explanation of this occurrence of the problem. nullable |
retryAfterSeconds
required |
integer (int32) | How long to wait before retrying, in whole seconds, carrying the same figure as the `Retry-After` header. Always at least one: a value of zero would invite an immediate retry that is certain to be rejected again. |
