Built-in Connections and the API key catalog.
Built-in Connections
These are first-class integrations, authorized over OAuth rather than by pasting a key.
A connection can hold multiple accounts — use Add another account when you need
separate identities for separate workspaces or clients.
Alert channels
Telegram and Slack are connected here too, but they carry alerts rather than data. Connect one and you get pinged when a colony stalls — and you can reply in the chat to keep it moving, without opening the app.API Keys
Everything else is an API key. The catalog is large — several hundred entries covering CRMs, enrichment and data providers, warehouses, databases, and email delivery. Each entry lists exactly the fields it needs, from a single key to a full connection (host, port, database, user, password). Sort by Most used to surface the common ones, or search if you know what you want. Several entries link to How to get key, which saves hunting through a provider’s docs.The catalog is broader than what OpenHive can currently complete a connection for.
Entries that aren’t wired up yet show Connect disabled, so you can see what’s
coming without starting a flow that can’t finish.
