# Create a subscription for a client

`POST /clients/{id}/subscriptions`

## Request

- Base URL: `https://api.hypamoon.com/api/v1`
- URL: `https://api.hypamoon.com/api/v1/clients/{id}/subscriptions`
- Auth: one of:
  - HTTP bearer
  - OAuth 2 (authorization code, authorization URL `https://app.hypamoon.com/oauth/authorize`, token URL `https://api.hypamoon.com/oauth/token`, scopes: `clients:write`)

A subscription on your agency's own payment account, with the client project in the metadata: the payer pays the first period through checkout_url, which also sets up the mandate; after that the payment provider charges every month or year. Not every payment account supports this yet; a 409 says so. Events: client_subscription.active, client_subscription.payment_paid, client_subscription.payment_failed and client_subscription.canceled.
