Authorizations

Authorization
string
header
required

Use a Bouclay secret key (sk_test_..., sk_live_...) or restricted key (rk_test_..., rk_live_...).

A secret key can call every endpoint. A restricted key can only call the endpoints its scopes cover. A scope is {resource}:{access}, for example customers:read or refunds:write, and write includes read. GET requests need read access and everything else needs write, except POST /subscriptions/{id}/items/{item}/preview, which only needs subscriptions:read. A request outside the key's scopes gets 403 permission_denied naming the missing scope, and its Idempotency-Key is not used up.

Publishable keys (pk_...) are rejected by server-side API endpoints. A key's mode scopes what it can see and charge: a test key can never reach a live card.
