A few things people sometimes look for aren't built. Listed here directly so you're not stuck searching for a setting that doesn't exist. Rate limiting and CORS used to be on this list, they aren't anymore, see "Rate limiting, CORS, and authenticating incoming requests" for how those actually work today.
- Scheduling finer than once a day. See "Scheduling an endpoint to run automatically" for why, and for the manual external-cron workaround if you need a tighter interval without upgrading.
- GraphQL, WebSockets, or real-time push. Every endpoint is a synchronous request/response, there's no persistent-connection or subscription model.
- A separate staging environment. Use an endpoint's Enabled toggle to keep it off the public route while you build it, and Test Run to exercise it against real data before flipping that on.
Tip: None of these are accidental oversights we're unaware of, if one of them matters for what you're building, it's worth knowing upfront rather than after you've built around an assumption.
