}Delete a value
Works for a key the version no longer declares too: that is how an app frees room after dropping a key.
The scope depends on the owner type: business needs none; store needs the read_stores scope (permission stores:read); product needs the read_products scope (permission products:read); order needs the read_orders scope (permission orders:read); customer needs the read_customers scope (permission customers:read).

}Authorizations
An app access token from POST /apps/oauth/token, valid 1 hour. An offline token acts as the app; an online token acts as the app on behalf of one dashboard user (the intersection of both permission sets).
Headers
Makes a write safe to retry: the same key with the same method, path, query and body within 24 hours answers the stored result (Idempotent-Replayed: true) without running the write again. Only a successful answer is stored, so a retry after a failure runs. A key reused for a different request is 422 IDEMPOTENCY_KEY_REUSED; one whose first request still runs is 409 IDEMPOTENCY_KEY_IN_USE.
