Create a subscription order from a pre-built checkout session. Returns the PSP checkout URL — redirect the buyer there to complete payment and start the subscription. 
POST /v1/actions/subscription-order/create-order
Authentication: Session Token — see Customer Endpoints (customer or shopper role)

​
Behavior

  • Price snapshot — The subscription price is frozen at order creation (price_snapshot); two-phase pricing (regularPhase + optional specialPhase for trials) is supported.
  • Billing period mapping — weekly -> week/1, monthly -> month/1, quarterly -> month/3, yearly -> year/1.
  • PSP fault tolerance — If the PSP call fails, the local order is canceled and the error is surfaced.
  • Session pre-fill — billingDetail and buyerEmail from the request body override any pre-filled values on the session; if both are missing the request is rejected with 400.
  • Email normalization — buyerEmail is normalized with trim().toLowerCase() before use.
The following fields are sourced from the session and must NOT be sent in the request body: storeId, productId, billingPeriod, currency. They are ignored if provided.
