Path parameters

orgIdstringRequired
The opaque organization id issued to you, normally CUID-shaped (for example cmsx…). It is not an org_-prefixed alias. Pass it unchanged in every organization-scoped path.
linkIdstringRequired

Headers

Idempotency-KeystringRequired
A unique value per logical operation, 1-255 chars of A-Z a-z 0-9 _ . : -.
More
Reuse it to retry. Same key with the same body replays the stored response; same key with a different body is a 409, because answering with the first call's result would hand you a receipt for a payout you did not request. A 4xx releases the key, so you can fix the body and reuse it.

Reuse it; do not generate one per attempt. A key minted per attempt defeats replay entirely: every retry looks like a new request, so every retry pays. We also watch for an identical body arriving under a different key within 15 minutes and refuse it with DUPLICATE_REQUEST_DETECTED.

Records are kept for 7 days. That is a retention window only: there is no path where an expired key is re-executed.

Behavior

draft to sent. From here shareUrl serves the page. For a link offering card this also mints the hosted card page behind it, so the two cannot come apart: a page that says "Card" with nothing behind it is a buyer clicking pay and landing nowhere.

Publishing an already-live link is a no-op that returns it. A paused or expired link cannot be published again, and a draft whose expiresAt has already passed is refused with 400 LINK_EXPIRED before any processor call. Idempotency-Key is required on an API key.

If the card processor refuses, the answer is 503 with its reason and the link is unchanged. If it does not answer at all (a timeout or a 5xx) the answer is 500 INTERNAL, and the card page may have been set up: retrying straight away answers 409 ("being changed") until the attempt clears, after which publish again.

Responses

200The live link, status: sent, with shareUrl.

Body · CheckoutLink

idstringRequired
Use this in every /links/{linkId} path.
numberstringOptional
Inherited from the invoice shape. Always CHECKOUT on a link; internal, never shown to a buyer and never the wire reference (that is slug).
paymentReferencestring | nullOptional
Inherited from the invoice shape. Null on a link; a bank payer references the slug.
deepLinkstring | nullOptional
Inherited from the invoice shape: an avvio:// app link to the same page.
fromEmailstring | nullOptional
Inherited from the invoice shape. Your contact email as shown to the buyer, when set.
fromAddressstring | nullOptional
Inherited from the invoice shape. Your address as shown to the buyer, when set.
customerName | nullOptional
Inherited from the invoice shape. Always null; a link is addressed to nobody.
customerEmail | nullOptional
Always null on a link.
customerAddress | nullOptional
Always null on a link.
customerId | nullOptional
Always null on a link.
feeTotalstringOptional
Inherited from the invoice shape. "0" on a link; processing fees are on each payment, not the link.
settlementCurrencystringOptional
Inherited from the invoice shape. The stablecoin the crypto rail settles in when offered; informational on a card link.
settlementAmountstringOptional
Inherited from the invoice shape. The total in settlementCurrency.
dueTypestringOptional
Inherited from the invoice shape. Always on_receipt on a link; a link has no due date.
dueDate | nullOptional
Always null on a link.
paidAt | nullOptional
Always null on a link. A link never closes; each payment carries its own paidAt.
emailedAt | nullOptional
Always null on a link. Links are not emailed to a customer.
slugstringRequired
The public page's path segment (the end of shareUrl), the avvio_link value on a success redirect, and the reference a bank payer types.
statusstringRequired
draft is not publicly readable. sent is live. cancelled is paused and expired is past its expiresAt: both are terminal, and the page answers 410.
Allowed values:draftsentcancelledexpired
shareUrlstring<uri> | nullRequired
The page to send buyers to. Null only when the environment has no public page URL configured.
fromNamestringRequired

The catalog product it was made from; null for an ad-hoc link.
Show 2 properties
- idstringRequired
- namestringRequired
receivedobject | nullRequired
What the link has taken in, summed over its paid and refunded payments. Base units with decimals beside them. Null on the link until the first payment lands, so "never paid" is not a zero.

Errors

400
VALIDATION_ERROR (a field is malformed; errors names each), BAD_REQUEST (a request we understood but cannot carry out, named in detail: editing a published link, deleting one that was live, both productId and items), LINK_EXPIRED (publishing a draft whose expiresAt has passed), or, on a write, IDEMPOTENCY_KEY_REQUIRED / IDEMPOTENCY_KEY_INVALID (the header is missing or malformed).
401
The key was refused. Nothing ran.
- UNAUTHORIZED: missing, invalid or revoked, or a key on a route that does not accept one.
- KEY_EXPIRED: the key passed the expiry it was issued with. Issue a new one; an expired key cannot be rotated.
- KEY_IP_NOT_ALLOWED: the key is pinned to source addresses and this request came from another.
403
A valid key that may not make this write. Nothing was changed.
- FORBIDDEN: the key belongs to a different organization, or your business has not completed verification to accept payments; detail says which.
- ACCOUNT_BLOCKED: API access for your organization is suspended.
- LIVE_KEY_ORG_NOT_APPROVED: a live key, before we have approved your business verification. Use a test key until then.
- INSUFFICIENT_SCOPE: a read-only key.
404
No such link or product in this organization, or the id belongs to another one.
409
CONFLICT: another publish or edit of this link is in flight (retry after a moment), or the draft was repriced after its card page was set up ("Delete this draft and create a new one"). Or an idempotency conflict (IDEMPOTENCY_KEY_CONFLICT, IDEMPOTENCY_KEY_REQUEST_IN_PROGRESS).
429
Too many requests. The default ceiling is 100 requests per minute per API credential on a 60-second window. High-volume payout and reconciliation routes declare a 600/minute override, and batch submission a 30/minute ceiling. A separate 2,000/minute per-source-IP abuse ceiling always applies.

Obey Retry-After; it is in seconds and is authoritative. A 429 means the request was refused before the handler ran. Retry reads normally; retry an idempotent mutation with its same Idempotency-Key.
500
INTERNAL: the card processor did not answer while the card page was being set up. The link is still a draft, but the page may exist; a publish retried at once answers 409 until the attempt clears.
503
INTERNAL (status 503): card payments are not set up on this environment, or the card processor refused to set up this link (its reason is in detail). The link is unchanged and stays a publishable draft.

Error body · Error

typestringRequired
Stable machine-readable code.
detailstringRequired
What went wrong, in a sentence. Always a string, so detail.toLowerCase() is safe.
More
This is the field to read on BAD_REQUEST and PROVIDER_REJECTED, where the type alone does not name the condition.
messagestringRequired
The same text as detail, kept for integrations written before detail existed. Read detail.
resolutionstringOptional
What to do about it, when there is a specific answer. It is not on every error (it is absent on BAD_REQUEST, NOT_FOUND, PAYOUT_NOT_CANCELABLE and DESTINATION_ACCOUNT_NOT_FOUND), so treat it as optional and fall back to detail.
statusintegerRequired
HTTP status, repeated in the body.
statusCodeintegerRequired
The same value as status, kept for integrations written before status existed. Read status.
requestIdstringRequired
Quote this to support and we can find the exact request. Also sent as the x-request-id response header, which is the only place it appears on a successful response. Success bodies do not carry it. Send your own x-request-id on the request and we use it, so your trace and ours share one identifier; otherwise we mint one.
errorsarray of stringOptional
Present on VALIDATION_ERROR; names each field that failed.
originalIdempotencyKeystringOptional
On DUPLICATE_REQUEST_DETECTED only. Send the request again with this to receive the original payout instead of making a second one. Without it there is no way to recover except by risking a double payment.
originalPayoutIdstringOptional
On DUPLICATE_REQUEST_DETECTED only. The payout the first request created.
originalBatchIdstringOptional
On a batch DUPLICATE_REQUEST_DETECTED. The run the first request created.
originalRequestIdstringOptional
On a 409 PAYOUT_OUTCOME_UNKNOWN replay. The requestId of the call whose outcome is unknown; quote it to support.
existingRecipientIdstringOptional
On BANK_ACCOUNT_ALREADY_LINKED. The recipient in your organization that already holds this account.
existingMethodIdstringOptional
On BANK_ACCOUNT_ALREADY_LINKED. The payment method on that recipient.

Branch on type, never on the status or the message. Every error type is listed with what to do about it.
