# POST /api/v2/subscription-types

Create a subscription type

- MCP id: subscription-types.store
- Scope: api:write:subscription_types
- Permission: subscription_types::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 type and returns it in the detail view with a `Location` header.

`sort_order` is assigned by the server as one past the highest existing position and cannot be sent. Names are not unique, so two types may share one. Template lines are not accepted here: create them one request each through POST `subscription-types/{subscription_type}/items`, so sending items is a `422` `validation-failed` for an unknown key.

## 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): Subscription type name. It is also the name every customer subscription of this type is displayed under, so renaming a type renames what its existing subscriptions read as. Names are not unique.
- description (string or null, optional): What subscriptions of this type cover, as free text.
- default_billing_interval (string, optional): Interval a new subscription of this type is billed at by default. Omitting it on create yields yearly, the stored default, not the monthly that plnnrly's form pre-selects, which is a form convenience the API deliberately does not reproduce.
- auto_renew (boolean, optional): Whether subscriptions created from this type renew automatically by default. The value is stored exactly as sent; nothing forces it to `false`.
- active (boolean, optional): Whether the type is offered in the catalogue. It is a catalogue flag only: nothing in the application filters on it, so deactivating a type does not stop existing subscriptions of that type from being renewed or invoiced.

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

## Response 201
- id (integer, required): Unique identifier.
- name (string ≤ 255, required): Subscription type name. It is also the name every customer subscription of this type is displayed under, so renaming a type renames what its existing subscriptions read as. Names are not unique.
- description (string or null, required, multiline): What subscriptions of this type cover, as free text.
- default_billing_interval (string, required): Interval a new subscription of this type is billed at by default. Omitting it on create yields yearly, the stored default, not the monthly that plnnrly's form pre-selects, which is a form convenience the API deliberately does not reproduce.
- auto_renew (boolean, required): Whether subscriptions created from this type renew automatically by default. The value is stored exactly as sent; nothing forces it to `false`.
- active (boolean, required): Whether the type is offered in the catalogue. It is a catalogue flag only: nothing in the application filters on it, so deactivating a type does not stop existing subscriptions of that type from being renewed or invoiced.
- sort_order (integer or null, required, server-assigned): Position in the catalogue, assigned by the server on create as one past the highest existing position. It is the default sort key, and there is no way to reorder types through the API: dragging types into order in plnnrly has no API equivalent in v2.0.
- created_at (timestamp (YYYY-MM-DDThh:mm:ssZ), required): Creation timestamp.
- updated_at (timestamp (YYYY-MM-DDThh:mm:ssZ), required): Last-write timestamp; use for incremental sync. It also feeds the `ETag` revision, because a subscription type has no `version` field.
- deleted_at (timestamp (YYYY-MM-DDThh:mm:ssZ) or null, required): Soft-delete timestamp, `null` while live.
- items_count (integer ≥ 0, required): Number of template lines on this subscription type.
- links (SubscriptionTypeLinks, required)
  - self (url, required): The canonical URI of this record.
  - items (url, required): Template lines on this subscription type.
