IESO Retrofit Service Provider API is one of 9 APIs that [IESO](https://apis.io/providers/ieso/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Energy Efficiency, Service Providers, and Retrofit. The published artifact set on APIs.io includes API documentation.

A companion web service API documented in SPEC-232 for service providers participating in the Save on Energy Retrofit program, covering the service-provider side of project submission and management on the Online IESO platform. Participant-only; requires an IESO-issued API account. No public self-serve credential issuance is published. SPEC-232 documents the Appian root endpoint https://online.ieso.ca/suite/webapi/ with eight rft-sp-v1-* resource suffixes (applications, appdetails, appdoc, appcomments, facilities, facdetails, facdoc, persons), GET/PUT/POST/DELETE methods, API-key authentication in three forms, and the only published HTTP status code table in the IESO estate (200, 201, 400, 401, 403, 404, 408, 429). The sandbox and production root endpoint values are themselves redacted to "URL value" in the public PDF.
