Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Contact your SPP customer relations representative to request Data API access, since onboarding is not self-serve
Generate and install the client certificate required for mutual TLS authentication, using separate certs for test and production environments
Reference SPP's Data API Data Exchange Guide for the catalog of available reports and request formats
Pull settlement and marketplace reports per the endpoints defined in the Systems Interfaces Reference Guide
Track SPP's parallel Markets+ RESTful API rollout separately, since it is a distinct, newer system from the legacy Integrated Marketplace API
Known gotchas
The legacy Integrated Marketplace Data API uses certificate-based access provisioned manually by SPP staff — there is no self-service API key signup
Do not conflate the new Markets+ REST API (built for the Markets+ offering) with the existing SOAP-based Integrated Marketplace API — they use separate credentials and separate data models
