# POST /api/v2/subscription-products

Create a subscription product

- MCP id: subscription-products.store
- Scope: api:write:subscription_products
- Permission: subscription_products::create
- Needs the billing feature on your organisation
- Rate cost: 1 unit, write bucket. A write costs the same whatever `view` you ask for.
- Cache-Control: private, no-store

Creates a product and returns it in the detail view with a `Location` header.

Names are unique and deleted products count, so a name that matches a soft-deleted product is a `422` `validation-failed` with code unique; restore that product with POST `subscription-products/{subscription_product}/actions/restore` rather than retrying under a different name. `price_interval` is required: it has no default, and the monthly pre-selection in plnnrly's form is a convenience only.

## Parameters
- view (string, optional): Which field set to render.
- X-Request-Id (header, optional): A correlation id of your own. It is recorded in our logs next to the server's request id but never returned: the response header always carries the server's id. A value that does not match the pattern is discarded silently, never rejected.
- Idempotency-Key (header, optional): A caller-chosen key that makes this POST safe to retry. Replaying it returns the original response with Idempotency-Replayed: true.

## Request body
- name (string ≤ 255, required, unique): Product name as shown in the UI and on the subscription line. Must be unique across SubscriptionProduct.
- price_interval (string, required): Interval the sales price is charged per.
- description (string or null, optional): Invoice-line template for subscription lines built from this product. Supports the placeholder tokens {{$domain}}, {{$site}}, {{$server}}, {{$period}}, {{$product}} and {{$customer}}, which are filled in when the line is invoiced; the template itself is kept verbatim.
- is_hosting (boolean, optional): Whether this is a hosting product: one sold against a concrete site or server, which is what lets a subscription line name the infrastructure it covers.
- purchase_price (decimal (2 dp) or null ≥ 0, optional): What the product costs us, as a decimal string. Null when unknown. At least 0.
- sales_price (decimal (2 dp) or null ≥ 0, optional): What the customer is billed per interval, as a decimal string. Null when the line carries its own price. At least 0.
- vat_rate (integer or null 0 to 100, optional): VAT rate as a whole percentage: 21 means 21%, not 0.21. Null when the rate is decided at invoicing time.
- exact_item_id (string or null ≤ 255, optional): Exact Online article this product maps to, by Exact's own external identifier (`exact_items.exact_id`), not by a local id.
- exact_vat_code (string or null ≤ 255, optional): Exact Online VAT code, by code (`exact_vat_codes.code`), not by id.
- exact_cost_center (string or null ≤ 255, optional): Exact Online cost centre, by code (`exact_cost_centers.code`), not by id.

Unknown keys are refused with `422` validation-failed, naming the key.
