Four method-specific tools that let a flow call anything that speaks HTTP — the general-purpose escape hatch when there's no native integration for a system yet.
What it can do
- Send Requests Get / Post / Put / Delete — one tool per HTTP method, each with its own URL, so an agent only ever picks the method it actually needs.
- URL templating — build the request URL from flow variables.
- Custom name and description — so the agent understands what a specific request is for, not just that it's "an HTTP call."
- Headers, plus a Body or Body Schema on POST/PUT and a Query Params Schema on GET/DELETE.
- Max Output Length — truncate long responses so they don't overwhelm the agent's context.
Good to know
This is the same mechanism behind Custom Webhook triggers, just outbound — between the two, a flow can connect to essentially anything with an HTTP API.
