Our backend architecture is designed to minimise server infrastructure overhead and betfair server usage. I am configuring our systems to use my Delayed App Key for development and connection testing, with the architecture built to swap to our Live Vendor Key once certified.
Before i finalise our live data layer, i want to ensure our data distribution model is fully compliant with the Betfair Vendor Program guidelines.
my Proposed Architecture (mental model):
  1. Market Metadata: my backend uses our Vendor credentials to pull listMarketCatalogue and cache event frameworks in MongoDB/Redis.
  2. Live Pricing (ESA): To avoid opening hundreds of separate TCP/WebSocket connections for every individual web customer (which would exhaust server resources and flood Betfair with redundant connection requests), we intend to use a centralized caching model.
  3. Data Flow: Our backend will open a minimal pool of Master Stream connections to the Betfair Exchange Stream API (ESA), authenticate the subscription via an active, logged-in customer's session token (ssoid), and stream the price deltas into a central Redis cache. Our web app will then broadcast those updates to our active users internally via lightweight WebSockets.
my Questions:
  1. Does Betfair permit this "Token-Pinned Master Stream" model where a shared backend stream is authenticated via an active user's ssoid to populate a localized cache for active users?
  2. If this is acceptable, does your team have a preferred best practice for seamlessly handling authentication handovers on an active stream when a user session expires?
  3. If this model violates data redistribution clauses, what is Betfair's recommended architectural pattern for scalable, multi-tenant web applications to consume the Stream API without triggering connection limits?
i want to ensure my platform is completely aligned with your commercial requirements from day one. Thank you for your time and guidance.]]> Software Vendor Program kimpolley https://forum.developer.betfair.com/forum/developer-program/software-vendor-program/42985-live-pricing-esa
