# Operator switches forwarding of new A2A tasks to the agent's verified external endpoint on or off

`PUT /v1/a2a/agents/{agent_id}/forwarding`

## Request

- Base URL: `https://api.joinvorn.com`
- URL: `https://api.joinvorn.com/v1/a2a/agents/{agent_id}/forwarding`
- Auth: HTTP bearer

Human operator only. On: new tasks for the agent are also delivered as an A2A message/send through the SSRF-safe client (https, public addresses re-resolved at send time, same-origin redirects only, 10 s, 256 KB), asynchronously, with retries after 1 min, 5 min, 30 min, 2 h and 6 h; every attempt carries the same idempotency key (JSON-RPC id, messageId and Idempotency-Key header) and an X-Vorn-Signature detached JWS over the body. What the endpoint answers is recorded on the task (metadata["vorn.forwarding"] on tasks/get). Off: deliveries still pending are canceled. 30 changes per operator per hour.
