Authorizations

​
Authorization
string
header
required

OAuth 2.0 Authorisation Code flow for RTI User authentication and consumer consent. Each supplier operates its own OAuth server. In production, substitute the placeholder host with the relevant url from the Supplier Register. OpenAPI does not permit URI templates in security scheme URLs, so a placeholder is used here.

Response

Consumer-specific tariff pricing detail.
