List plan change products

GET
/products/{product_id}/subscription_change_products

The products a subscriber to this product may switch to on the same subscription plan: the active, not deleted products in the product's subscription_change_product_ids that still have the same plan. All of them come back on one page; offset and limit do not apply. The upgrade and downgrade settings are not applied here; they apply when a customer changes a subscription. Secret, trusted and limited tokens may call it.

Authorization

headerAuthorizationBearer <token>

A secret, trusted or limited token. See Authentication.

Path Parameters

product_id*string

The product id.

Query Parameters

Comma-separated child objects to return in full instead of as a URL, for example customer,payments. Use dot notation for nested objects (items.product), up to four levels deep. A single object takes up to 12 paths; a list takes up to 2, applied to every item. Extra paths are dropped without an error. See Expanding objects.

show?string

Comma-separated fields to return; all others are left out. Use dot notation for child fields (customer.email). You cannot send show and hide together (400). See Customizing output.

hide?string

Comma-separated fields to leave out of the response. Use dot notation for child fields (customer.email). You cannot send show and hide together (400). See Customizing output.

formatted?boolean

When true, the object also has a formatted child with amounts and dates as display text in the shopper's language and currency (for example $19.99 or November 7, 2026). The default is false. See Localized formatting.

The ISO 4217 currency to price the products in. It must be a currency the account can take payment in, or the request fails with 400.
