Mint a payment request's hosted pay page

POST

/v1/payment-requests/{request_id}/pay-link

curl --request POST \
  --url https://api.aerandil.com/v1/payment-requests/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/pay-link \
  --header 'Authorization: Bearer <token>'

• Production API

The page a guest pays a payment request on — a Stripe Payment Link for the request’s amount, limited to one completed payment, holding instead of charging for a preauthorization. The rail’s worker mints it after request_payment commits; this route mints it on demand when the worker has not (or could not), and returns a page already recorded as it is, so it is safe to repeat. The guest’s payment completes the request through the webhook; cancelling or expiring the request switches the page off. Gated on request_payment’s apply scope — whoever may ask the guest for money may mint the page they pay on; the verbs that record the page and its payment are the rail’s own and have no public apply. 501 unless AERANDIL_STRIPE_ENABLED=1.

Parameters

Path Parameters

request_id

required

string format: uuid

The pending payment request.

Header Parameters

Idempotency-Key

string

>= 1 characters

Opaque idempotency token (Stripe-shape). Repeated POSTs with the same key replay the original response within the cache TTL rather than creating a duplicate object.

Responses

200

The page the guest pays on.

Headers

Cache-Control

string

Always no-store. Object and link state is live data and is never cacheable.

403

The bearer authenticated but does not hold the scope this operation requires.

Media typeapplication/json

Structured error wrapper. Every non-2xx response from any Aerandil endpoint serialises to this shape; the HTTP status carries the failure class (4xx/5xx), the body adds a stable code for programmatic dispatch plus a human-readable message.

object

error

required

object

code

required

Stable, programmatic error code (e.g. unauthorized, forbidden, not_found, invalid_body, invalid_url, precondition_failed, no_secondary_key). Clients dispatch on code, not on the message (which may be localised or contextualised in future versions).

string

instance_id

Request-id correlation handle echoed on the request-id response header — support teams correlate without scraping logs.

string

message

required

Human-readable explanation of the failure.

string

parameters

Per-error structured detail. The shape varies by code (e.g. forbidden_action carries {"action": "..."}; precondition_failed carries {"current_version": N}).

Example^generated

{
  "error": {
    "code": "example",
    "instance_id": "example",
    "message": "example",
    "parameters": "example"
  }
