API ReferenceSubscriptions

Preview a renewal date change

Preview a new renewal date before confirming it.

Use this endpoint when the subscription's billing-date policy requires a preview before confirmation.

Check shift_billing_date in the subscription's capabilities first. The current Stripe and PayPal flows do not support renewal-date changes and return 422. See Handle subscriptions for a guarded example.

POST
/v2/subscriptions/{productSubscription}/actions/change-renewal-date/preview

Authorization

AuthorizationBearer <token>

Provide your SellApp API key as a bearer token.

In: header

Path Parameters

productSubscription*integer

The productSubscription path parameter.

Header Parameters

Idempotency-Key?string

Caller-generated key for safely retrying this operation. The JSON idempotency_key field is also accepted; when both are sent, the header takes precedence.

Lengthlength <= 128
X-STORE?string

Store slug. Required for OAuth access tokens. API keys may omit it to use their current store, or the first accessible store when no current store is selected.

Request Body

application/json

Request contract for a provider that supports renewal-date changes. Current Stripe and PayPal flows reject this operation.

TypeScript Definitions

No successful response is available from the current Stripe, PayPal, or Razorpay integrations. Check subscription capabilities first; unsupported renewal-date changes return 422. The 200 schema describes the provider interface, not currently available provider behavior.
