Create a checkout session
Mint a signed hosted-checkout token (cs_…). The returned url is the page you
send the payer to · the only place a card is ever collected.
mode=payment · a one-time charge.
mode=subscription · opens a subscription and bills its first cycle. Needs a
billingMode: subscription product
(CHECKOUT_SUBSCRIPTION_REQUIRES_RECURRING_PRODUCT), and is required to open one ·
a recurring product sold as payment is charged once and never renews. Renewals
are then driven by Suby.
mode=setup · stores a card without charging, for later off-session debits
(POST /v3/payments/off-session). No Payment is created. Requires a pay_as_you_go
productId, which names what the payer authorises without pricing the page. A
priced product here is refused (CHECKOUT_SETUP_REQUIRES_PER_USE_PRODUCT), a
per-use one on any other mode too (PRODUCT_PRICED_PER_USE).

Optional key (≤255 chars, e.g. a UUID v4) making this POST safe to retry · the response is cached 24h and a retry with the SAME key replays it instead of re-executing. The same key with a different body → 422 IDEMPOTENCY_KEY_CONFLICT; a retry while the first is in flight → 409.

Body
application/json
mode=payment takes exactly ONE pricing intent · productId, lineItems (no recurring product in a basket) or priceCents + currency. mode=subscription takes productId alone. mode=setup takes none and rejects lineItems, priceCents, currency, discountCode and taxBehavior · its productId names, it does not price.
payment one-time charge · subscription opens a subscription and bills cycle 1 · setup stores a card without charging.
Available options:
payment, subscription, setup Redirect after a successful payment.
Redirect if the payer cancels.
Pricing intent A · a single product. Exclusive with lineItems / priceCents. On mode=setup it names rather than prices.
Example:
"pro_abc123"
Pricing intent B · 1–20 product lines charged as one Payment. Exclusive with productId / priceCents.
Required array length:
1 - 20 elementsShow child attributes

Pricing intent C · ad-hoc amount in minor units, string of digits. Requires currency. Exclusive with productId / lineItems.
Pattern:
^[1-9]\\d*$Example:
"1999"

Pattern:
