IESO Registration System Facilities API

aid: ieso:ieso-registration-facilities-api
name: IESO Registration System Facilities API
description: 'A REST API on the Appian-based Online IESO platform for retrieving and maintaining facility
  registration data. SPEC-249 documents the base path https://online.ieso.ca/suite/webapi/ and the facilities
  resource at https://online.ieso.ca/suite/webapi/reg-v1-facilities/, with a sandbox at https://onlinesandbox.ieso.ca/suite/webapi/.
  Authentication is by Appian API key, supplied three ways — HTTP Basic with the key as username-and-blank-password
  (or the reverse), an Appian-API-Key header, or an Authorization Bearer header — over mandatory HTTPS;
  a missing or invalid Authorization header returns 401. There is no self-serve key issuance: the organization''s
  registered IESO Rights Administrator must request an API machine account with "Registration API" access,
  so this is a market-participant-only surface.'
